1. What is Science?

2. Science  An organized way of studying things and finding answers to questions.

3. What is Physical Science  Physical science is the study of the physical world around you. Learn about electricity, magnetism, energy, periodic table, force, matter, waves and electromagnetism.

4. Critical Thinking  A progress that uses skills to solve problems. Separate important information from unimportant information. This is called a skill.

5. Solving Problem  Requires organization in the form of procedures called the Scientific Method.

6. Scientific Method  Step 1: State the Problem – a question that scientists would try/like to answer. Needs to have an independent variable and a dependent variable. This is always in the form of a question.

7. Step 2: Gather information Background information about the variables is needed to develop a good hypothesis.

8. Step 3: Form a hypothesis A prediction that can be tested.

9. Step 4: Test the hypothesis with an experiment. Your experiment should have an independent variable, dependent variable, and a control variable.

10.  Independent variable- controlled by the scientist.  Dependent variable- the part of the experiment that is being measured.  Control variable- cannot be changed in the experiment. It is the standard of comparison in an experiment. The control variable stays the same.

11. Step 5: Collect and analyze data Organize data in order. Study and explain results.

12. Step 6: Draw conclusion Putting everything together. Accept or reject hypothesis. Repeat experiment.

13. Theory and Laws

14. Scientific Theory An explanation of things or events based on scientific knowledge. It is the results of many observations and experiments. (Ex. The Big Bang Theory)

15. Scientific Law A statement about how things work in nature. Can be proven time and time again. (Ex. Newton’s Law of Motion)

16. International System of Units (SI): Standard system of measurement used by scientist. This is known as the metric system. (EX.) Unites States System Metric System Inches Centimeters Feet yard Meters Cups Milliliters Gallons Liters Fahrenheit Celsius

17.  Why do scientists around the world use the metric system?

18. List three ways physical science has enhanced life? 1. 2. 3.
