Preface

In this page, I will say thank you to Allah to gives me life until right now I write

this research paper about my observation of the green beans. I would thank to

my parents who teach me about the world, everything. Also, I would like to

thank to my science teacher, Miss. Dewi Pramesti Kusumaningrum who

teaches me about many things in scientific explanations. She opens my eyes

about the scientific world around us such as cells organism, living creatures,

and many more. And also to my friend, Chika who gave me more green

beans while many of mine are having the bad quality. And to also my friend,

Azzah who helped me when doing this science reports because I had many

struggles to write many new things for me using scientific explanations and

scientific words. Also, this is my first time to write a science research paper

after doing an experiment.

By doing this experiment, I could know how the farmer grows the green beans

in the farm that I would not know if I am not doing this experiment. By doing

this, I could know what kind of materials that I should prepare before planting

green beans and where should I put the pot of the beans to get more high

quality and less timing.

But then, I feel really sorry to my teacher, Miss Dewi cause I could not keep

her trust to me to keep all of those cups properly and put on save place. I was

lost my A cup. I don’t know what was happened that time, but all of I know

about that cup is I have lost all of 5 beans inside it without any cotton layers

anymore.

Anyway, I am really happy to do this experiment because by doing that,

because it can fulfill my curiosity of the growth of the beans. At the first time, I

thought that every single plant would grow faster if they receive high amount

of sunlight, especially when we place it in a place where receive direct

sunlight.

Purpose

To support the topic of ‘From Cells to Organisms’ in our Science class this

term and we are learning about cell organisms and living creatures, we would

do the observation of the green beans growth in 4 different cups that receive

different amount of sunlight. Each cup will contain of 5 green bean seeds, 2 of

the cups will layered by cottons and the others will layered by a hand of soil.

One cup of cottons and one cup of soil will be placed where the amount of the

sunlight is in the high level, such as outside the building. The other 2 will place

where the amount of the sunlight is lower than the outside building, such as in

the guest room or another room that receive low amount of sunlight.

We will observe how the beans grow from the first day of planting until a week

of observation. At the end, we will get the different results for each cup that

we have. Which cup that has the higher green bean tree and how is the

branch looks like. It is hard, big, or thin. And how the leaves look like. By

observing how the plants look like, we can determine what kind of things that

we need. How much the growth for each day and how high the beans will

grow in a different materials that we need to prepare before the plantation and

in the different place. By that, we would know what kind of materials and

where should we put the pots of beans to get the best quality.

Introduction

In this term, we learn about cell organisms and also living creatures in our

world, such as plants, animals, and humans. To help this topic on this term,

we want to observe the growth of the green beans that we think it is more

easier to do because it does not need more space, more maintenance, easy

to find the materials, and we can observe it just once a day. That is why we

chose this experiment.

Green beans also known as string beans or snap beans are also known

scientifically as Phaseolus vulgaris. They are available year around with a

peak season of May to October. It has green and dry skin.

Probably they were derived from their ancestors in Peru, then they spread to

South and Central America by migrating Indian tribes. Then, they entranced

Europe around the 16th century by Spanish explorers.

The best quality of beans that we can measure is from its skin and color. If the

skin is soft, green, and has a firm texture without brown spots and bruises, so

you can know that it is the best quality beans.

Green beans are good to protect your cardiovascular system from blood fats

because it has antioxidant to keep your body save from bad radicals which is

containing viruses that danger for our body. It can through our immune

system and start to attack our inner organs.

Nowadays, the biggest commercial producers of fresh green beans are

Argentina, China, Egypt, France, Indonesia, India, Iraq, Italy, Mexico,

Netherland, Spain, and United States.

Hypothesis

The green beans that putted in a place that receive direct sunlight will grow

faster with the ones that putted not in the direct sunlight because plants

usually need more sunlight to grow up more higher and faster, and also to do

photosynthesis.

Also, the beans that placed in the cups with soil will grow faster and more

greenish than the ones that placed on cottons because the roots of the beans

will grow easily and it will absorbs more water inside the soil. So, the plants

can easily do the photosynthesis and growing up using more water inside the

soil, more place for roots to grow, and receive more sunlight at the day.

So, the beans that placed in the cups of soil and receive more sunlight will

grow more faster and higher that the others. The beans that inside the cups

but not receive more sunlight will grow slowly because they have not much

sunlight to do photosynthesis.

In fact, after we did the observation, the beans that placed on cottons and soil

but not receiving more sunlight grows faster than the ones that receive full of

direct sunlight for 5 days long. The seeds go rotten and it goes dying. The

growth is much more slowly than the other 2 cups.

If we compare the cup with cottons and the one with soil but placed not in the

place where receive more direct sunlight, the growth of the beans on the

cottons are more higher because they have more water to absorb, although

they have not much space to live because the wet cotton layers are much

more thick than the soil that can be separated easily to give more space for

the roots.

Materials and Methods

Materials:

• Green beans seeds

• 4 empty pots

• White cottons

• Soil

• Water

Methods:

• Label your 4 pots that you’ve prepare is before with A, B, C, D

• Put some cotton layers on 2 different pots (ex: A, C) and a hand of soil

into the others (ex: B, D)

• Place 5 seeds of green beans in each of the small pots, but not close

enough for each other

• Put the A and C pots in a place that receive the direct sunlight, and put

the B and D in a place that not receive the direct sunlight.

• Start the observation

Results

After doing the observation of the green beans growth, we will receive the

result that is the beans in the soil and cotton in a place that not receive the

direct sunlight are faster to grow up than the ones which are put in a place

that receive the direct sunlight.

Green beans are considered as warm weather crops which need warmed

temperature soil and a little cup of water to keep the beans moist so it could

grow faster. It likes high temperature above 65° F, around 59.4° C. It will

produce green and healthy beans. Green beans will receive direct sunlight at

least 6 hours to get high quality beans.

That’s why the beans that are located not in the directed sunlight grow faster

and higher than the ones that receive direct sunlight.

The ones placed in a place with full direct sunlight will receive more amount of

sunlight, more than 6 hours. It wills grows as not faster as the ones that put

not in the directed sunlight place. The beans will go dry and the water is going

empty because of the evaporation, so the plants will get rotten cause they had

no water to absorb and help them to grow, and dry space.

Conclusion

If you think that all of plants that receive much sunlight and enough water with

soil can grow faster, I suggest you to do this experiment because it will make

your eyes open in a scientific world. Not all of the plants that receive much

sunlight can grow through the heat and wind. Green beans are warm

weathered crops. It is easily to get rotten if the temperature is too hot.

From this experiment by doing the observation of the green beans growth, I

get the information that green beans need warm watered soil above 65°F and

less sunlight to grow faster and more higher than if we put it in a dry place. It

will cause much evaporation in the cup, so the plant will get rotten because it

receives more than 6 hours of sunlight and almost 2 times of it (12 hours of

sunlight), more than the limit. It will go dying and it could not grow anymore.

The roots will go much long than in the cotton to find water, because it could

not find any water near it to absorb as the energy to keep grow up and still

alive.

Also, we need cottons that trapped the water to keep it stay in the cup, so the

plant will easily to get water from the cottons. It prevents the dying beans

because of much sunlight that it receives. Although, the cottons usage in this

experiment makes the roots have not much space to grow because the layer

is thick enough to get through by it.
