Presentation
Eureka Science Fair was born from the science fair that happened for
years at the Joinville International School. Affiliated to FEBRACE and
MOSTRATEC, the two biggest national science fairs, Eureka aims to develop
and expand the scientific, cultural, entrepreneurial and innovation knowledge in
Elementary School students to High School. The fair that was once only for the
school community of the Joinville International School now receives other guest
schools, widening its influence. In 2017 the fair received its own name, Eureka
Science Fair. The students of Joinville International School elected the slogan
of this edition as "Finding our place in the Science Universe", proposed by the
5th grade student Heloísa Liz Nogueira.
During the months of April and May, students were involved in discussion
and practices on themes proposed by the supervising teachers to investigative
processes that involved a lot of creativity and criteria in the development of
significant projects for individuals and for society as a whole.
More than in previous years, Eureka Science Fair focuses on
interactions between students from different schools, as well as among
teachers, professionals and scientists who exchanged experiences, analyzes,
reflections and discussions that stimulate the development beyond the barriers
of knowledge. Students are led to think on a global scale by realizing different
world realities in a context of diversity in academic and cultural backgrounds.
Eureka Science Fair brings projects developed in the areas of
Engineering, Individuals and Society, Biology, Math, Chemistry and Physics,
presented by students from Elementary to High School, guided by the teachers
of the respective schools.
We believe this to be the first year of many to come for Eureka Science
Fair. We count on the collaboration and appreciation of all those who truly
believe in ideas which motivate talents in the fields of sciences.

A SOCIAL EXPERIENCE ON HONESTY Isabela Bastos Luiza Roggia
Valentina Cavasolla Helena Cristina Máximo (Supervisor)
Escola Internacional de Joinville – Joinville-SC
Our project is based on an investigation on how society reacts to our social
experiment, which is about trust and honesty. We leave a table with candy and
a ticket giving the orders to the client to leave their money in the box. The
objective we tried to achieve was to see if trust and honesty are aspects present
in the region. Our first procedure was to make the sweets, so that they were
presentable for sales. Then we selected places to put the tables where people
passing by could see. We realize that many people are suspicious because
they know that there is cruelty among people. Most sought out some salesman
and some people thought it was a joke. We managed to realize that some
thought of stealing, and others thought it was a project, because something like
this is not very common. Another thing that caught our attention was that people
from smaller cities bought much more than in the center, for example, with this,
it was possible to notice that they have more confidence because they know the
people around them. We can say that our goal has been achieved because it is
not honesty but trust, because to buy something that you do not know where
you came from, you have to trust in society in general and believe that people
practice citizenship.
KEY WORDS: CONFIDENCE, HONESTY, CITIZENSHIP.

BANALIZATION OF OBSESSIVE-COMPULSIVE DISORDER - OCD
Beatriz Soldaini Grieco Cabral De Mello Giuliana Monteiro Pignatiello
Maria Eduarda Fagundes Lemos Adriana Bollmann Soares (Supervisor)
Escola Internacional de Joinville – Joinville-SC
Generalization and normalization are very present in the lives of people who are
diagnosed with psychological illnesses, causing the diagnosed person to end up
denying his condition and not looking for an adequate treatment. In this project
we decided to explain the seriousness of OCD because it has little recognition
as a disease in society, and how this normalization affects the life and treatment
of people. Through questionnaires, we conducted a research with people
around us, we ended up discovering that the banalization of OCD is strongly
implicit in our environment, being most often compared to a simple and
controllable habit. After a great research of data using our questionnaires and
psychology books about the disease, we came to an answer to the problem of
how to make people realize the seriousness of psychological diseases and how
to make them explicit for the population, drawing attention to how this affects
And modifies their lives.
KEY WORDS: OCD, NORMALIZATION, DESEASE

CHILDREN IN THE WAR OF SYRIA Camilli Eduarda Cordeiro Rabello
Julia Franco Zago Sofia Klujszo Utzig
Andréa Gonçalves de Araújo (Supervisor) Escola Internacional de Joinville – Joinville-SC
We chose this topic because we found it very interesting. Besides the desire to
learn more about the subject, we also want to discuss and teach other people
about it. We started by researching and reading about the topic on the Internet.
We read a little about everything, we inspire ourselves to start writing from our
point of view. We wrote about the Syrian war, and how it harmed and is harming
children, primarily affecting their feelings, their future and their health. In
addition to future (serious) consequences to the economy of the country. We
learned a lot from the project, and were encouraged to help. The project's
conclusion was that these children are really being affected, will suffer greatly in
the future and need help. We sent an email to the United Nations to help, but so
far we have not received any answers.
KEY WORDS: CHILDREN, SYRIA AND WAR.

CLEPSYDRA, THE WATER CLOCK Elena Cereghino Hernandez
Joaquim Rota Vieira Vítor Augusto Hertel Rovaris
Francisco de Paula Oliveira Fernandes (Supervisor) Escola Internacional de Joinville – Joinville-SC
Have you ever stopped to think about how our ancestors measured the time in
the beginnings of humanity? Probably you already think about the “sun watch”,
but this is not the only clock that the humans used to measure the time. We
introduce you Clepsydra, the water clock! We chose this project because we
thought that it would be interesting to know a bit of the past which many people
didn’t know. To make the Clepsydra, we cut in the middle a 2 liter plastic bottle,
and made a hole in the center of the bottle cap. The part with the cap was put
upside-down in the base and water was added. When the water was running,
we counted the time that we wanted, and after this time had passed we
recorded how much the water got up. We have reached our objective, but we
noticed that it is not very precise, sometimes the clock deregulated a bit,
because every time we would count the time it splashed water out of the bottle.
Time wasn´t clear, but we could have a notion about how our ancestors
measured the time. It was a good experience knowing a bit more about the
past.
KEY WORDS: CLEPSYDRA, WATER, CLOCK.

END OF PROBLEMS FOR WHEELCHAIR USERS Arthur Blind Pope
Maria Júlia Amancio Padilha Nicolas Nass
Francisco de Paula Oliveira Fernandes (Supervisor) Escola Internacional de Joinville – Joinville-SC
Our project speaks about the physically handicapped and with the question of
how they were treated over time and how the difficulties faced by the physically
disabled have changed over time. Our hypothesis before researching all this is
that we thought the wheelchairs in the Middle Ages were well, care, and
respected precisely because they have a difficulty affecting their lives that stops
them from doing many things and our methodology is to do a research. After
doing the project and to do the interview to help the handicapped to be more
respected we searched our project and did the logbook and made the model.
The research showed us that the life of the handicapped was very difficult and
the interview showed us that the handicapped still have many problems.

The title of our Science Project Family changed throughout the time came from
our students while studying one of transdisciplinary theme Where we are in the
place and time. One of our indicators were Describe how family changed
throughout the years. Represent on the graph and charts changes which
occurred during the time in the family. In the beginning of the research students
made the hypothesis that There are no many members in their family. After the
investigation of reasons students got very interested in the subject of their
family. They proceed family interviews investigating quantities of member in
their families.

HOW SOCIETY DEALS WITH “HOOKING UP” (BRAZILIAN SLANG “FICAR”) – GENDER
DIFFERENCES Brenda Lopes Thiago Amin
Helena Cristina Máximo (Supervisor) Escola Internacional de Joinville – Joinville-SC
The objective of this project is to find out if teenage girls suffer any kind of
prejudice (by the own teenagers) because they have “physical” relationships
(dates) with many people. The methodology adopted by the group was a
questionnaire with 6 closed questions and 1 open question. The questions were
elaborated in a way in which, by analyzing the answers, it would be easy to
identify if a person is prejudiced. For this, the survey was given to 43 people
who know the members of the group, including 22 girls and 21 boys aged
between 12 and 17 years. This research was also done with 40 other people
(20 boys and 20 girls), still between 12 and 17 years old, but were randomly
chosen in a mall, which the young people attend a lot. The result, as expected,
was that girls suffer more prejudice by relating to multiple people. The most
interestingly, girls proved to be more conservative than boys. While most of the
boys answered in the open question that has relations with a lot of people at a
single party (and/or would like to have more), the girls answered that they only
have relationships with 1 to 3 people on average during a party which for them
is more appropriate.

OW THE CUBAN DICTATORSHIP INFLUENCE THE POPULATION
Arthur Krammel Gustavo Brandao Lacerda
Maria Eduarda Kushino Borges Andréa Gonçalves de Araújo (Supervisor)
Escola Internacional de Joinville – Joinville-SC
We decided to choose this Project for the reason that one of the members of
the group called Gustavo, had two teachers and a friend in his school of Brasilia
that had already lived in Cuba, this is something that can make it easier to make
our Project. Beside that, we are studying about America in Geography, and this
can be an adjunct to our theme. Our methods are search in internet about Cuba
and the Cuban dictatorship and the interviews done by a member of the group
to the Cubans that live in Brasilia. This integrant went to Brasilia and talk to his
knows. All of them said that the conditions of life in Cuba is horrible but mainly
that many children and teens has a proper education but didn’t had the
necessary materials to the classes. For example, in medicine, when you need a
respiratory mask for someone that can’t breathe alone, they didn’t had this
mask. The also said about the scarcity of food, but this isn’t the main cause of
the slump. After we analyzed our interviews, we saw that many people are
suffering in Cuba because of the Socialism and the dictatorship implemented by
Fidel and that Raúl is still using the method of his brother. In this way we saw
that, our hypothesis that say that the Cuban dictatorship is influencing in a
negative way was right, but we discover that is worse than we imagined.

Escola Internacional de Joinville – Joinville-SC
Our Project has the objective of seeing how humans in the past made their
things and take one of this customs and apply to our lives. Were there when the
idea came of make a raft wit materials simple to find, as it would have a little
cost and maybe would help in poor places close to water. To make the raft, we
use a base of bamboo that would be use by the natives that came to America
and we use a string to make the knots. We chose her because it has a small
cost and can help people that live close to rivers.

We will re-make the Baghdad battery to see the number of volts it produces,
and if we can light a led. The Baghdad battery was found in the thirties be the
archaeologist Wilhelm Konig and it is thousands of years old. Because energy
today causes too much pollution, and not all people have access to it, we
wanted to try an energy source that would not pollute much and be accessible.

THE CONFLICT IN SYRIA MAY AFFECT VARIOUS GENERATIONS Eduardo Blind Pope
Felipe Bonilauri Ferreira Maria Isabella Schneider
Andréa Gonçalves de Araújo (Supervisor) Escola Internacional de Joinville – Joinville-SC
The war in Syria is one of the biggest conflicts today. Many generations will be
severely affected, as well as severely damaged. The poor living conditions in
Syria are the main factors behind the recent increase, in the number of Syrians
seeking refuge in Europe. Refugees are adopting negative coping strategies,
such as child labor, school dropout, begging, and prostitution. They need a lot
more support. In this project we want to report to everyone what is the reality for
these generations, and how we can be damaged in the future as a
consequence, with many relevant and conscious research, we will show how
the various generations have been or are being damaged by the War in Syria.
We conclude that, the impact of the conflict in Syria can affect several
generations and threaten security throughout the Middle East. The depth of the
Syrian tragedy is painfully reflected in the number of victims. The atrocious
experiences reported by the survivors reveal violations of human rights, war
crimes and crimes against humanity. The destructive dynamics of the civil war
endangers future generations and threatens peace and security throughout the
region.

THE PAPYRUS Fernanda Grieco Acquati
Leonardo Gayoso Ziemath Kotzias Leandro Odorizzi
Francisco de Paula Oliveira Fernandes (Supervisor) Escola Internacional de Joinville – Joinville-SC
We chose this project because we found it interesting to know how the books
were done back in the past, because nowadays there are machines that already
do this for us, but, at that time, none of these existed. Our project was meant to
recreate an old book, in that our question was about how the books were made
in the past, together with our hypothesis of being easy to make an old book (but
with only one sheet) because the materials are not so difficult to found. We
researched more about books because we felt that more knowledge about
books, paper and their production could help us more in our project. We cut the
tip of the papyrus, cut it into thin strips, we took the strips and put them in a
bowl of water (after waiting 72 hours to follow our project), put the strips on top
of the wooden plank, put the strips also on the felt and cover them with a
second piece of felt. Then we put the "package" between the dough and the
wooden plank to flatten. When it dried, we used the roller to make it flattened
like a sheet. Using materials such as papyrus (paper used in ancient Egypt), felt
and wood, we recreated a one-page book in the style of the ancient books.
Contrary to what we initially thought, it is difficult to make a papyrus book
nowadays, since materials (such as papyrus) are rare.

WAR IN SYRIA THREATENS HISTORICAL AND CULTURAL MILLENNIUM HERITAGE
Breno Portela Alves Leonardo Lussoli
Andréa Gonçalves de Araújo (Supervisor) Escola Internacional de Joinville – Joinville-SC
We did the project because we wanted people to think about how war can affect
the culture and coexistence of others. We have researched the losses of
cultural and historical devastation as dramatic as the current conflict in Syria.
Besides, scientists have had to leave the country because of the war. The
conclusion of the war is the same as we thought. When the war comes to an
end, one must do a colossal job to rehabilitate these monuments that are
suffering damage for other reasons as well.
KEY WORDS: WAR, SYRIA, PATRIMONY.

WATERWHEEL Matheus Hansenn
Rafael Krüger Senra Vicente da Costa Landowski
Francisco de Paula Oliveira Fernandes (Supervisor) Escola Internacional de Joinville – Joinville-SC
Our group researched and built a water wheel. Our first question is to know if it
could move water, but, because of the difficulty of execution we changed our
objective to investigate the production of hydroelectric energy of the water
wheel. The built wheel was made of simple and accessible materials. We tried

WHY MOVE? Grade 4 students
Dorota Szczepanska Oliveira (Supervisor) Edimara da Luz (Co-Supervisor)
Escola Internacional de Joinville – Joinville-SC The question of our Science project Why move? came from our students while
studying one of transdisciplinary theme Where we are in the place and time.
One of our indicators was Describe and classify reasons why people migrate.
After the investigation of reasons students got very interested in the subject of
migration. They made a connection between the first human migration and
migrations of their family. In the beginning of the research students made the
hypothesis that there are no many migrants in their family and reasons were in
most of the cases economic. They worked with following didactic materials: O
que há de África em nós and documentary movie The first human Odyssey.
One of the biggest impact during our research was the Field Trip to National
Museum of Migration and Colonization in Joinville.

Escola Internacional de Joinville – Joinville-SC
Our project came up with the idea of traffic safety, we wanted to see if the kind
of music (by varying the bpm) we heard can influence driving. So we took the
genre of music most played on the radios (country music) and a genre that we
believe has greater influence during driving, so we choose rock. We put
different people to do a simulation in a game, as long as it played the music.
This way we evaluate if the genre and the bpm of the music influences driving.

HOW THE ELECTRONIC CALCULATOR WORKS AND AN ALGEBRAIC TRICK
Caio Petroncini Manoela Morais Serratto
Sofia Melo Stevens Escola Internacional Unisociesc de Florianópolis – Florianópolis-SC
The initial question was: How does the electronic calculator work and an
algebraic trick? Our initial hypothesis was that all possible operations were pre-
programmed into the calculator in the form of a multiplication, addition,
subtraction, and division table, and that the calculator would just pick up the
operation that the person typed and return the corresponding answer. To find
out how it works we conducted an online research and learned that the
calculator does the calculations and not simply has the information saved in the
form of a table. In order to demonstrate our findings on how the calculator
actually calculates, we constructed wired logic gates, LEDs, and transistors on
an integrated circuit board, which together do logic operations with 1's and 0's.
The binary result is then converted to numbers with base 10. We modified our
initial question to "how the electronic calculator calculates" since our hypothesis
has not been proven. We ended up working with an algebraic trick to show an
application of the calculator usage, which looks like a "magic trick".

MUSIC INFLUENCE ON THE HEART BEATING OF AN INDIVIDUAL

Escola Internacional de Joinville – Joinville-SC
With a marvelous curiosity which knows no limits, we (Marina and Lívia) came
to wonder: could, for any instance, music influence on the heart beating of an
individual? Our group theorized, before the experiments, that music did
influence the BPMs (Beats per minute) of the individuals. This thought is
supported by the fact that, between other factors, the emotion is one of the main
causes of the cardiac frequency; knowing that music has the capacity of
transmit emotions, we want to test how this factor changes the BPM of our
volunteers and if music and bpm have an interrelationship. The methodology
that we chose to use was to submit volunteers to three different songs, two of
which they can choose (as long as they consider one of them cheerful and the
other one depressing) and the third one had to be a constant for all volunteers.
Then, we would measure the cardiac frequency of the volunteers during each
song. It is necessary, for methodology’s sake, that the volunteers hear each
song separately and with a short time break between the hearings, in order to
avoid the influence of a song over the others.

PARAMETERS ANALYSIS OF ROCKETS LAUNCHING FOR MOBFOG
Bernardo Enrique Colossi Gomes Felipe Bastos Santini
Gustavo Gonzaga Petry Escola Internacional Unisociesc de Florianópolis – Florianópolis-SC
This work started with the intention to participate in the Brazilian Rocket Show
(MOBFOG), promoted by the Brazilian Astronomy and Astronautics Olympics
(OBA). G10 students (Escola Internacional / SOCIESC / Florianópolis) were
divided into two groups, one responsible for experimenting the chemical
properties of the project (the best ratio of reagents), and the other for
experimenting the physical properties of the project (better angle for launching a
rocket) - with the technique used it was possible to obtain a range of
approximately 10 meters. The peer work between the two groups composed a
significant part of the theoretical basis for this research, which focused basically
on investigating the factors that can affect the maximum reachable distance by
a PET bottle rocket. They are basically the pressure obtained from the reaction
between Sodium bicarbonate and vinegar, the different types of rocket models,
different models of launch bases, and different ways of starting the reaction.
Changes were made and tests were carried out, of which only one was
successful, obtaining a reach of 77.9m. We concluded that the changes have
greatly improved the rocket's reach that still have possibilities to provide better
results.

We did the project because we wanted to know if our theory was true. We
tested our first tests of balance, intellect and motor coordination in a volunteer,
the volunteer was well in the proposed tests all coordinates widened after a
match of a game (the time was generally ten minutes). However, our first tests
were not successful because the volunteer played daily. The second volunteer
did not play much video games, so the result was that he or she could not
concentrate or he or she would take too long to concentrate. Our final result
unfortunately was negative because the volunteer could hardly concentrate on
the tests proposed because it concentrated too much in the game.

We chose this project because we wanted to help the kids to learn Science,
specially how happen the evaporation, the growing of plants, the layers of the
soil and show how some animals act in their habitats. We decided to do a
terrarium, so we planned what kind of plants that we were going to use, and
where we are going to construct these habitat, we want something big, so it can
call the attention for learning and help to see better all process. We got some
flower and plants that we found around the school. To do the layers we search
how the soil work, we made four different layers that maintain the plant alive.
We got some insects like ants and spiders. We observed that some plant grew
and create new ones, some of them start to get dry. We could see that some
water evaporates and stay in the plastic that we put above the terrarium and the
oxygen made by the photosynthesis, because the plastic start to fill up. Now we
are going to pick two groups of five volunteers, for group A to learn the lesson
with the terrarium and the group B learning without the terrarium. In the final of
this process, we will make a test with both groups and see with each one is

Our group studied about deforestation; we wanted to identify which soil filters
better the water, with or without plants or with any other material. We believed
that the soil with plants would filter better than any other. Our procedure we
used three empty bottles of water which were cut to make a model. Inside the
bottles, we put soil. There was only soil in one of the bottles, on the other, we
also put grass and on the last one, there was soil and dry leaves. Water was
poured on all the three bottles and soil started to filter the water. A recipient was
placed under each bottle to collect the remaining water. Than we let the
remaining water “resting” during the night. In the other day, we see what bottle
most filter the remaining water. The bottle with grass was the best filter. The
bottle just with soil is the second one that most filter the remaining water and
the last one was the bottle with dry leaves. However, we thought that the bottle
with dry leaves would filter the most. Now we understand why the vegetation is
so important to the soil.

“Hard work is the yeast that raises the dough”- Anonymous (HARING; PLAKKÉ,
2010). Yeast is a single celled organism that grows when combined with
elements such as sugar, amino acids, oxygen, nitrogen compounds and
temperature. Yeast is a fungus that is sensitive to light, a reason to why it is
stored in dark places. Light of moderate intensity inhibits respiration and growth
in yeast. So, how does light affect yeast fermentation? The yeast ferments the
sugar, eliminating the CO2. That´s the reason why in the end of the experiment,
the CO2 needs to be measured, so the amount of CO2 released will show how
much the yeast had grown, making it possible to compare from dark to light.
The objective of the project is to see the difference between the growth of the
yeast in light and in dark, to find the most appropriate place to store it. The
experiment was made in four trials for each type of environment, being they
light and dark. Quantities of sugar, yeast, and water were measured to react
between them and half of bottles were place on the dark and the other half on
the light. Four hours after the group measured the CO2 with the sensor.

experience, we took pictures of different people, doing different facial
expressions (happy, sad, mad, and scared). Then we showed the horses the
pictures of the humans’ expressions and recorded how they react to them, for
later write the results. We discovered that the horses show similar emotions to

the interdependence between men and environment. After being inquered with
the line of inquiry How much garbage do we produce every day, they had a
doubt: where does the garbage go and how much time does it take to
decompose? So after collecting the recyclable waste from the snack for 10
days, we chose some of them to see what would happen if they were left in the
environment for 1 month. And the banana peel was chosen as a parameter of
comparison, which is supposed to be decomposed in a shorter time. In a plastic
bottle with soil, we put paper towels, biscuit pack (BOPP) and banana peel
under sun and rain. After a month, all the material was taken out and it was
observed that: the banana was decomposed and the biscuit pack was still
intact, confirming most of our hypothesis.

spills affect the environment? Are there ways to clean the soil and the water
completely? Based on those questions, this project aims to replicate the effects
of an oil spill and compare the absorptivity of different tools used for cleaning up
an oil spill in water. Oil spills like this are very damaging, but they are not the
only source of oil that is polluting our waters, but it is one of the biggest.
Therefore, cleaning up the ocean is an important issue, not just because of

PHYSIOLOGICAL RESPONSES CAUSED BY THE USE OF DIFFERENT METABOLIC ROUTES
Gabriela Franzoni Lara Beatriz C. Gomes
Luísa C. Marinho Vinícius Campbell de Lacerda
Escola Internacional Unisociesc de Florianópolis – Florianópolis-SC
The research carried out refers to the differences in the metabolism during the
practice of aerobic and anaerobic exercises. It’s very important to know which
activity triggers each metabolic route, mainly for raising awareness of one's own
personal barriers and limits. The most important requirement for aerobic
respiration is oxygen. Oxygen (O2) and carbohydrates will be drawn into the
mitochondria, one of your cell’s organelles, and will be subjected to the Krebs
Cycle, which is a process that involves over 40 chemical reactions. According to
Neil Campbell in “Biology: Exploring Life” (2006), the result of this combination
is a molecule of carbon dioxide (CO2), which is expelled by the cells, and
Adenosine Triphosphate, better known as ATP, the molecule that energizes
your cells in order to provide all the functions they perform. In anaerobic
respiration, firstly, the stored ATP will be used to provide explosion in short
distance and high intensity exercises, according to the “training design” page of
the “ptdirect” website (link on the references). This phase, known as ATP-PC,
lasts for about 15 seconds, and could be compared to the 1st and 2nd gears of
a car. The next phase of anaerobic exercises is called Glycolytic and includes
the transformation of stored glycogen (C24H42O21) into glucose (C6H12O6)
(ptdirec.com). Then, in order to create more ATP molecules, the glucose is
broken down by a series of enzymes. This breaking down results on the
production of pyruvate (C3H4O3) and positively charged hydrogen ions (H+),
that make your muscles very acid. The binding of both molecules results on the
creation of lactate (C3H5O3), which may provide fatigues and the feeling of
burnt for about 30 or 45 seconds. This phase goes through the supposedly 3rd,
4th and maybe 5th gear of a car. All these processes work in the cellular level,
though, it's possible to observe differences between people who practice
aerobic activities compared to those who practice anaerobic activities, such as
the amount of sweat released, and the tiredness and redness shown on their
faces at the end of workout. Therefore, can these extracellular differences
which are easily noticed in our bodies be measured, confirmed and related to
the kind of activity performed?

We decided to do this project because we wanted to end the problem of don’t
knowing which sunscreen brand to buy. We choose to test the brands by
passing sunscreen in plants. If the plants die is because they stopped to do
photosynthesis that mean that the sunscreen worked. We bought twelve basils
and passes different brands of sunscreen in them respectively. We keep track
of the plants for a week and see the sunscreen effect on them. The plants had
lost many leaves and the majority of them ended black. We concluded that the
sunscreen may have done more than just stop the plants on doing
photosynthesis like don’t letting the plants “breath” or contaminating them with
chemicals. We reached our objective in defining that the best sunscreen brand
in avoiding UVA and UVB rays is the brown one.

generator that would turn on a watch using the sustainable energy of a small,
clean potato. We made some modifications in the design so that the generator
would light a lamp of LED of 200w. When he showed the site to us we thought
the idea was great because we could create a new form of energy that is less
polluting to the environment, unlike the conventional battery whose discharge
causes pollution as it takes a long time to decompose( from 100 to 500 years).
After our third and last experiment, we conclude that 8 potatoes can generate
2.20w of energy. Considering that a small LED bulb needs 200w, we conclude
that approximately 727 potatoes would be needed to it light up.

Nowadays our society is very dependent on petroleum, however petroleum is
one of the principal reasons of the Global Warming and it is almost over around
the world. The polystyrene is made of petroleum and it takes many long years
to decompose, and when it does, a lot of polluting waste remains. We are going
to produce polystyrene of green coconut, the original one is made of petroleum.
Petroleum is a fossil fuel that is provoking an ecological problem that the world
is passing through those days, another reason is that the original Styrofoam
takes a lot of time to decompose; also the industries that produce petroleum
generate a lot of smoke in the air, that contributes for the Global Warming, and
as much we can avoid using the petroleum we also avoid the Global Warming.
To do our prototype we are going to use green coconut, mix it with homemade
glue, and shape it into a box. We are trying to make it waterproof and thermic.

Our project is based on avoiding fires on the forests that are caused by the São
João Balloon (Balão de São João), that is a balloon utilized in an event here in
Brazil, called “festa junina” or “festa julina”. We choose this project because we
have concerns in the Brazilian environment and we want to keep doing our
traditions. To keep the original tradition of the balloon, which means that we
have to use fire as the source to make the balloon fly (the fire can cause burns
in the forest in contact with the normal paper that we make the balloon with,
when it is already on the ground but the fire can be turned on again), we
decided to use a nonflammable tissue. After researching, we found a “manta de
Teflon”, which does not catch fire and have the needed weight for the balloon.

We had this idea through our theme this year: sustainable energy. Our project
aims to demonstrate that sunlight can light a mini LED light showing this in a
dollhouse so that people can use a way to demonstrate solar energy without
damaging nature. Our idea came through an inspiration to help preserve nature.
We have decided to put the title '' light for everyday '' so people can see a
project that will generate enough energy to light up a dollhouse, but our goal is
for people to use it in their homes on a day-to-day basis. Nowadays many
people already have solar energy in their homes, but the system is connected to
CELESC and other energy companies. We think this idea of the house is
creative because if you have a solar plate at home your account may decrease
about 90% in the Ecoa they do not pay only the consumption at night. The eco
is a place where they provide solar panels and we went there to visit as a
school trip we learned a lot about sustainable energy.

We carried out this project to help people who need help to feed themselves the
robot is powered by rechargeable batteries that cannot charge with solar
energy. So we decided to build a robot that goes through this task, and that
robot will lessen that need. And while the robot feeds like people need, other
people work to support the family. To contribute to our project, each member of
the group brought materials to carry it out. All the members of our group help to
assemble, prepare and test the prototype so that we can achieve our goal. So
we made our first project that did not work because it glued a spoon with tape.
In the second experiment we set up a Lego robot and the third column with
spoon with hot glue and left the pot at an appropriate height and tested. And in
this experiment (third) it worked because the spoon did not fall and the jar did
not move.

HOW DO FACIAL EXPRESSIONS AFFECT THE
PERCENTAGE OF SIMILARITIES USING FACIAL
RECOGNITION Lucas William Pscheidt
Daniel Schlickmann Bastos
Anderson Madruga dos Santos (Supervisor) Escola Internacional de Joinville – Joinville-SC
Why do we have to abstain from smiling at any document photo? These genre
of questions, to be more specific, facial recognition and its variables, was the
topic explored by this project. In order to achieve this, our group built a simple
program with the help of Microsoft Cognitive Services Face API. This API gives
us to freedom to use Microsoft Face Recognition algorithms, therefore, our
group wrote scripts that, when executed, would connect to their server and
return us, for example, the similarity between the train photos and the test one.
6 emotions were chosen to be part of the sample size, these were the following:
happy, sad, angry, mad, surprised and a control one, the neutral face. The first
step consisted on recognizing the facial landmarks and features in 9 neutral
photos that would be used as the independent variable. Then, we would train
the dataset with the neutral photos and, for last, each of the expressions was
tested against the train data, thus, returning the similarity between the person
with a neutral facial expression and, for example, a smiling one. The results
found were that, when compared to the similarities between the neutral face,
facial expressions do indeed impact the resemblance percentage. The control
variable had a mean confidence of match of 87%, while the 5 emotions do not
vary much their percentage, they do differ against the neutral face by
approximately 17% less. Therefore, it can be concluded even though the type of
emotion does not affect the final result when compared against other emotions,
it does if contrasted with the neutral face, as it is seen with its percentage of
recognition/match.
KEY WORDS: FACIAL EXPRESSION, FACIAL RECOGNITION, AND

Our objective doing this project is to desalinate water. It is known that the
majority of population don´t have access to drinking water, because it is scarce
in many countries and places; in addition to that, desalination is expensive,
unaffordable for many social classes. We made two different experiments:
distillation and freezing. To do the distillation of salt water we will put a bowl
covered with plastic film with an empty cup in the middle, and let it catch sun.
After some hours the cup on the middle will be with drinking water, the salt will
stay in the bowl while the steam will not come out of the bowl because of the
plastic. To do the freezing, we will need to freeze the water in a low
temperature, then we will need to defrost, then make this more times, and then
it´s ready.
KEY WORDS: DESALINATION, FRESH WATER AND LOW COST.

Sometimes we need a way to make our plants survive through long-lasting
periods, like when we travel or do things really time consuming. We designed a
way that is efficient and easy to maintain our plants while not worrying too
much, being able to leave the plants alone for some time. In this project, we
decided to produce cheap and relatively easy way to take care of plants, aiming
to help people with little budget needing to take care of either big quantity of
plants or plants that require a lot of water. We used simple materials such as
plastic bottles and strings to produce a plant vase that can keep a plant humid
for more than 2 weeks (depending on the initial amount of water and the type of
plant). We believe that our prototype worked very well because our plant
survived more than 2 weeks without replenishing water. We used very
accessible materials making it easy to construct.

Our project consists in a natural sunscreen. You can choose the factor that you
want, and it is less expensive. You can save money, and have a great result at
your skin. We decided to make a sunscreen because many people, due to
financial conditions, can´t afford the product and are at risk of being burned or
even getting skin cancer. The group aimed to produce an affordable sunscreen.
To make it, we used coconut oil, zinc oxide, Hipoglós cream, and liquid soap.
Then we mixed all the ingredients together to form our sunscreen. We used
some plants to test our project, if the plant died it would mean that the
sunscreen had worked, because the plant wouldn´t have been able to make
photosynthesis, meaning that the human skin would block the sun. We
observed that our sunscreen worked, because our plant had died.

Our Project consists in Rainwater recollection. The Project was carried out with
the intention of saving water, we made that project because nowadays the
people spend a lot of water, and in our project, we are saving the water. We
constructed a model of a house that uses water from the rain to flush the toilet
and to water the plants. We used simple materials such as cardboard, ink, hot
glue, straw, and biscuit.

REPLACING PET BOTTLES FOR BIODEGRADABLE PACKAGES

Escola Internacional de Joinville – Joinville-SC
PET bottle’s pollution cycle is initiated by the extraction of petroleum, production
of the preform and the bottle, cleaning, and distribution of the product. It is only
possible to recycle 50% of the PET bottle, based on this information we can
estimate that the bottle produces eight times its own weight in residues. It has
been analyzed that PET bottles are the greatest cause of pollution on Earth.
Recycling the bottle is an option, but we need to consider the impacts caused
by this procedure, like taxes (2% higher than in industries that produce regular
PET bottles in Brazil) and the higher cost of such production. In this project, we
present you a solution for the environmental problems caused by the improper
use of the PET bottle, aiming to insert edible and biodegradable materials in
people’s life. We intend to make a bottle prototype, it is made of water, Calcium
Chloride and Sodium Alginate. To comprehend our project, it is necessary to
understand the following key terms: Biodegradable, edible and PET.

Our Project consists in a belt that could turn 360o degrees for you to sleep on
the back seat of the car calmly and comfortably. The first idea was to create a
platform for you to be straight and comfortable but we realized that this would
not work. So we went on to another idea that consisted of a cross belt coming
from under the seat but we realized that it was not going to work either.
Therefore, we decided that we could do a type of vest that turned 360 degrees
that you could lie down and still be comfortable. To make the prototype we used
a car, felt and a doll. We hit the car twice in low speed and the doll didn’t crash
against the car seat, one time in medium speed and twice in high speed and in
none of them our doll was in danger on the contrary, our doll remained safe and
comfortable on the back seat of our car. Our group concluded that the 360o seat
belt is safe can be used in real life situations.

When we started creating the idea for the project for Eureka, we decided to
make this boat powered by solar energy because traveling is part of tourism
and creates jobs. But the conventional method, with oil fuel, pollutes the seas
and the air, so we chose this project. When the purpose of the engine works,
we are happy and excited, however, when there is no sun, we were very
disappointed with the result, as we expected the solar plate would work. For
some time our boat did not sail because of the lack of sun, but the solar panel is
powerful and on sunny days, the boat moved as expected. The second time, we
made the model of the boat with Styrofoam and pet bottle, but our solar panel
ended up spoiling, because if you get too busy with the wires, the board and the
motor do not work, so we could not test that day that there was Sun. The last
time we decided to make a Lego boat, we decided because this was the best
option we had at the moment, compared to the models produced earlier,
however the sun did not appear, and the solar plate was still damaged. Our
conclusion is that we did not get to do our initial idea, but over time we were
changing our mind from some videos, but our actual conclusion is, that we did a
Lego boat, and another day, we'll see If our boat really works.

The dirty water problem has provoked so much sicknesses all over the world
expired us to realize a water-cleaner, that is basically a pyramidal machine that
uses solar energy to evaporate the dirty water and clean even salty water. The
main idea was discovering if the sun can clean the water by it heat. We used
acrylic to build an acrylic pyramid. The dirty water is going to be introduced and
it will fill the pyramid 1cm of water per time used. After that, the water is going to
evaporate because the acrylic material that the pyramid is made to widen the
solar rays. We decided to paint the pyramid base black, this way, the ambient
inside the pyramid gets hotter and hotter, this way, it evaporate faster. After
evaporating, little drops of water will appear in the top of the machine, drain on
the surface and fall clean and “drink” out of the pyramid.

The Project’s intention was to make an easy-to-carry umbrella that features the
ability to retain the Rainwater that pours over it; so the individual can later filter it
for daily house-hold activities, and even ingestion. Though this will require a
specific filtering procedure, to eliminate present pathogens. The Water
Recycling Umbrella is divided into two structures: the umbrella, and a water
catching and transporting potable hexagon made with PVC tubes, it is to be put
over the umbrella, it also meant to serve as thorough, sanding and cutting the
tubes as a necessary step to be able to correctly put and glue them together.
Transparent hoses were attached to the structure, to lead the water to the
through secured at the bottom of the umbrella’s handle.
As a team, we believe that this Project can and will have a positive impact n
water efficiency.

people who live in places with storms that leave people without light. We use a
wooden box, a propeller, a wheel, a motor, a led lamp and an incandescent
lamp. We can light a LED light, make the base of the design (the box), paint it,
put decorations, and find a motor. We managed to have a positive result by
lighting a led and incandescent light.
