Describing the organization of the universe.
matter and energy
Understanding the natural laws that govern the universe.
belief that all events follow a set of laws that do not change
Deducing and applying natural laws.
science as a process

*We will explore Physics using inquiry through observation.

8. 1.1 Inquiry
Three valuable things are learned by discovering the natural laws through inquiry:
It includes very practical knowledge.
Once you know how something generally works, you can often figure out how to make it work for you.
You will learn to solve real-life problems.

9. Using Problem Solving Techniques
Step 1
Determine what the problem asks you to find out.
Step 2
Identify the information you are given.
Step 3
Identify laws or relationships.
Step 4
Apply the given information and the relationships.

10. Foundations of Physics Units

11. 1.2 Development of Scientific Knowledge
Models, Evidence, Analysis and Theories

12. 1.2 Development of Scientific Knowledge
Importance of Experiments
We use experiments to test and evaluate theories.

13. 1.2 Development of Scientific Knowledge
Scientific Evidence
Graphs and charts
Images and sketches
Measurements and data

14. 1.2 Development of Scientific Knowledge
Scientific Knowledge and the Solar System
Early civilizations believed the Earth was covered by a dome on which the sun, stars and planets moved.
In the Middle Ages, people thought the sun, stars and planets circled the Earth.
Today we know the earth and planets orbit the sun.
