1. Opener #1 - Tuesday, August 16, 2011 Answer these on new sheet of paper in complete sentences. #1. How many unexcused absences can you have before you will be denied credit for a semester class? #2. How many tardies can you have and NOT receive EMD or other punishment? #3. What do you think of when you think of science? Write answers in complete sentences. You do not have to write the questions.

2. What is Science? Science – means “to know” What is a goal? (student responses) Goal of science Is to understand the world around us…

3. Learning About the World Science is a way of learning more about the natural world. Scientists want to know why, how, or when something occurred. This learning process usually begins by keeping your eyes open and asking questions about what you see. 1 1 What is science?

4. Asking Questions Science can attempt to answer many questions about the natural world, but some questions cannot be answered by science. Questions about art, politics, personal preference, or morality can’t be answered by science. Science can’t tell you what is right, wrong, good, or bad. 1 1 What is science?

5. Possible Explanations Science can answer a question only with the information available at the time. 1 1 What is science?

6. Possible Explanations As new information becomes available, explanations can be modified or discarded and new explanations can be made. 1 1 What is science?

7. WEDNESDAY - August 17, 2011 - Opener #2 1. What are some things that you were able to determine about items in your box from yesterday (or today 7th period)? 2. What could you infer or hypothesize about items in the mystery box? 3. What types of experiments and tests could you do to find out more about the items in your box? 4. What is something that you might never be sure about in your box unless it was actually opened? TURN IN STUDENT INFORMATION SHEETS AND TEAM SUPPLIES (TISSUES, BATTERIES, HAND SANITIZER...)

8. Questioning and Observing Investigations often begin by making observations and asking questions. 2 2 Science in Action ACTIVITY

9. Facts, Theories, Laws… Facts – verified by measurement, observation, or other method. Example with and w/o Mystery Boxes… Scientific Theory – logical explanation for events which occur in nature… Examples: Cell theory, theory of evolution,... Sci. theory vs. theory in other apps.

10. Scientific Theories An attempt to explain why a pattern observed repeatedly in the natural world is called a scientific theory. Theories in science must be supported by observations and results from many investigations. They tell WHY... They are the best explanations that have been found so far. 1 1 What is science?

11. Scientific Theories Theories can change. As new data become available, scientists evaluate how the new data fit the theory. If enough new data fails to support the theory, the theory can be changed to fit the new observations better. Scientific theories are always being questioned and examined. To be valid, a theory must: explain observations be repeatable be predictable 1 1 What is science?

13. Scientific Laws A rule that describes a pattern in nature is a scientific law. For an observation to become a scientific law, it must be observed repeatedly. 1 1 What is science? IT TELLS WHAT was observed as pattern - often mathematical equation showing the pattern or formula...

14. Scientific Laws A law, however, does not explain why, for example, gravity exists or how it works. A law, unlike a theory, does not attempt to explain why something happens. It simply describes a pattern. Example: Law of gravitation free fall... Newton’s Laws... 1 1 What is science?

15. Skip - Examples/Illustrations of Laws Examples of Laws: Law of gravity… Illustration with law of conservation of energy with pendulum (tetherball) and/or rotation of chair with weights… Note to me... Next is Phys.Sci.S1.1 clips along with Balloon demo...

16. 1.1 What Is Science? In July 1997, the six-wheeled Sojourner rover became the first robot to explore planet Mars. Sojourner was built to answer questions about the nature of Mars. Science involves asking questions about nature and then finding ways to answer them.

17. 1.1 What Is Science? How does the process of science start and end? Science From Curiosity

18. 1.1 What Is Science? Have you ever checked what was living at the bottom of a pond? Taken off the cover of a baseball to see what was inside? Tried putting more chocolate or less in your milk to find out how much would give the best flavor? These are all examples of curiosity, and curiosity is the basis of science. Science From Curiosity

19. 1.1 What Is Science? Science begins with curiosity and often ends with discovery. Science From Curiosity

20. 1.1 What Is Science? In some experiments, observations are qualitative, or descriptive. (ex. bubbles, makes blue solid ppt...) In other experiments, observations are quantitative, or numerical. (It produced 5 grams, speed was 20 km/hr... Some questions—for example, how the universe began—cannot be answered by direct observations and measurements but only by other kinds of evidence. Curiosity provides questions, but scientific results rely on finding answers. Science From Curiosity

21. 1.1 What Is Science? Science is a system of knowledge and the methods you use to find that knowledge. The goal of science is to expand knowledge. What is the difference between pure science and applied science? Technology is the use of knowledge to solve practical problems. The goal of technology is to apply knowledge, thus applied science... Science and Technology

22. 1.1 What Is Science? The telephone was invented in 1876. By 1927, it was possible to make a phone call from New York to London. The first mobile telephones, invented during World War II, paved the way for modern cellular phones. At each step, new science was applied to improve the technology of the telephone.

23. 1.1 What Is Science? What is the relationship between science and technology? Science and Technology Science and technology are interdependent. Advances in one lead to advances in the other.

24. 1.1 What Is Science? What are the branches of natural science? Branches of Science: Natural vs. social sciences

25. 1.1 What Is Science? Natural science is generally divided into three branches: physical science, Earth and space science, and life science (biology). Branches of Science - Social vs. Natural

26. 1.1 What Is Science?

27. Chemistry is the study of the composition, structure, properties, and reactions of matter. Physics is the study of matter and energy and the interactions between the two through forces and motion. Physical science focuses on nonliving things.

28. 1.1 What Is Science? Geology is the study of the origin, history, structure, and systems of Earth. Astronomy is the study of the universe beyond Earth. The application of physics and chemistry to the study of Earth is called Earth science.

29. 1.1 What Is Science?

30. Biology includes the physics and chemistry of living things, as well as their origin and behavior. Biologists study the different ways that organisms grow, survive, and reproduce. The study of living things is known as biology, or life science.

31. 1.1 What Is Science?

32. Much of biology involves changes that are part of chemistry, while much of chemistry is defined by interactions that are part of physics Biophysics is a growing area of physics that applies physics to biology. There is overlap between different areas of science.
