What is Science?
Science Defined
Science is the process we use to learn information and a body of information Science is a process we use to learn
information. The process involves using the scientific method
Science is the body of knowledge we build through our investigations.
What Do Scientists Do?
Scientists.. Study any aspect of
the world, solar system, and universe
gather new information and modify prevailing theories and develop new theories that help us understand old observations in a new way
Qualities of a Good Scientist
What do you think?
Good scientists practice accurate record keeping, openness, and replication essential to investigator’s credibility with other scientists and society
Scientist Qualities Explained
Record keeping: (note taking, data collection) is very important because it is very easy to for get small details that may turn out to be very important.
Openness and honesty: is absolutely essential for conducting good science. Scientists are trained to always try to remain unbiased and report the results of an experiment as they are and not how they “were supposed to turn out”.
Replication: is the process of repeating an experiment several times. It is important because the more times an experiment is repeated with the same result the more confidence we have in that result. If an experiment is done only once the result may be due to random chance.

Why is Studying Science Important?What do you think?
In your science journal, write why you feel studying science is important
The Scientific Method
Steps of The Scientific Method
1. Problem/Question2. Observation/Research3. Formulate a Hypothesis4. Experiment5. Collect and Analyze Results6. Conclusion7. Communicate the Results
Develop a question or problem that can be solved through experimentation.
Question/Problem
Make observations and research your topic of interest using reliable sources.
Make Observations/Conduct Research
Formulate a Hypothesis
Predict a possible answer to the problem or question. Example: If soil temperatures rise, then
plant growth will increase.
Experiment
Develop and follow a procedure. Include a detailed materials list. The outcome must be
measurable.
Do you remember the next step?
Collect and Analyze Data
Modify the procedure if needed. Confirm the results by retesting. Include tables, graphs, and
photographs.
Draw a Conclusion
Include a statement that accepts or rejects the hypothesis.
If possible, make recommendations for further study and possible improvements to the procedure.
Share Your Results
Be prepared to present the project to an audience.
Expect questions from the audience.

The Metric System
Measurement In Science
MEASUREMENT
Measure length to the nearest millimeter,
mass to the nearest gram,
volume to the nearest milliliter,
force (weight) to the nearest Newton,
temperature to the nearest degree Celsius,
and time to the nearest second.
By the end of this unit you
must be able to:
Length

UNIT: Meter (m) Centimeter
(cm) Millimeter (mm)
What is it used to measure?• How long is the line?• How tall is the tree?• How far did they run?
INSTRUMENTBalance
UNIT:Gram (g)Kilogram (kg)Milligram (mg)
Mass

What is the Metric System?
The metric system is a system of weights and measures that was first implemented in 1795 in France. Scientists around the world use it as the international standard to clearly communicate data.
The Metric System provides…. Simplicity Consistency
Length
The basic unit of length in the metric system is the meter and is represented by a lowercase m.
Metric Units
1 Kilometer (km) = 1000 meters
1 Meter = 100 Centimeters (cm)
1 Meter = 1000 Millimeters (mm)
Mass
Mass refers to the amount of matter in an object.
The base unit of mass in the metric system in the gram and is represented by g.
Metric Units 1 Kilogram (km) = 1000 Grams (g)
1 Gram (g) = 1000 Milligrams (mg)
Volume
Volume is the amount of space an object takes up.
The base unit of volume in the metric system is the liter and is represented by L or l.
Metric Units 1 liter (L) = 1000 milliliters (mL)
1 milliliter (mL) = 1 cm3 (or cc)
Note: Liquid volume should be measured in liters or milliliters while solid volume should be measure in cm3
Read the measurement based on the bottom of the meniscus or curve. When using a real cylinder, make sure you are eye-level with the level of the water.
What is the volume of water in the cylinder? _____mL
What causes the meniscus?
A concave meniscus occurs when the molecules of the liquid attract those of the container. The glass attracts the water on the sides.
Measuring Volume
We can measure the volume of
irregular object using water displacement.
Amount of H2O with object = ______
About of H2O without object = ______
Difference = Volume = ______
Volume of Irregular Objects
