  4. 1. WHAT IS SCIENCE? The word science comes from the Latin word scientia, which means “knowledge”. Science is knowledge!

  5. 1. WHAT IS SCIENCE? Dictionary Definition Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.

  7. 1. WHAT IS SCIENCE? Dictionary Definition Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.

  8. 1. WHAT IS SCIENCE? Dictionary Definition Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.

  9. 1. WHAT IS SCIENCE? Dictionary Definition Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.

  10. 1. WHAT IS SCIENCE? Dictionary Definition Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science is based on evidence!

  11. 2. SHAPE OF THE EARTH What shape is the Earth? Based on simple observation, the shape of the Earth is… To answer this question we need… EVIDENCE! FLAT! Flat Earth Theory

  12. 3. FLAT EARTH THEORY What shape is the Earth? A scientific THEORY is a conclusion supported by all known evidence. If NEW evidence is discovered which cannot be explained by our current theory, then the theory is WRONG and it must be changed. Flat Earth Theory

  13. 4. NEW EVIDENCE Alexandria Eratosthenes Shadows are not the same length at all places on Earth. Syene 2,000 years ago in Ancient Egypt

  14. 5. MODIFIED THEORY The Earth is a very large sphere. Spheroid Earth Theory

  15. 6. EVEN MORE EVIDENCE According to modern satellite data, the shape of the Earth is actually… Oblate Spheroid

  16. Science builds knowledge! Flat Earth Theory Spheroid Earth Theory Oblate Spheroid Earth Theory

  17. 7. WHAT IS PHYSICS? The word physics comes from the Latin word physis, which means “nature”. Physics is the scientific study of the natural world.

  18. 7. WHAT IS PHYSICS? Dictionary Definition Physics is a natural science that involves the study of matter and its motion through space and time.

  19. 7. WHAT IS PHYSICS? Dictionary Definition Physics is a natural science that involves the study of matter and its motion through space and time.

  20. 7. WHAT IS PHYSICS? Dictionary Definition Physics is a natural science that involves the study of matter and its motion through space and time.

  21. 7. WHAT IS PHYSICS? Dictionary Definition Physics is a natural science that involves the study of matterand its motion through space and time. Physics is the study of everything!

  22. 8. PHYSICS AND MATHEMATICS The goal of physics is to create mathematical models that explain how the world works. Mathematics is the language of physics.

  23. 8. PHYSICS AND MATHEMATICS Basic Physics Formulas

  24. 8. PHYSICS AND MATHEMATICS Maxwell’s Equations of Light

  25. 9. THREE BRANCHES OF SCIENCE Biology Chemistry Physics plants and animals chemicals and matter the physical world Every science can be explained in terms of physics!

  26. all living things are made from cells Biology cells are made from chemicals Chemistry chemicals are held together by electrical forces Physics

  27. 10. VENN DIAGRAM OF SCIENCE biology physics chemistry Every science is related to physics in some way.

  28. 11. COURSE TOPICS This year in physics we will learn about… force motion gravity momentum energy heat magnetism electricity waves

  29. 12. CHECK FOR UNDERSTANDING a. Where does the word “science” come from? b. What is the goal of physics? c. Why is it important to study physics? d. Write down a question that could be answered by using physics.
