1. Physical Science Mr. Bunt Room R-201

2. Classroom Guidelines 1. Use Common Sense at all times 2. Do not give me any more gray hairs 3. Golden Rule Other than that, you’re expected to follow the school handbook guidelines and are subject to consequences that match the offense

3. Grading Homework Policy Homework Policy Content will be divided up into units with a unit test Content will be divided up into units with a unit test Labs will be conducted at least once per unit Labs will be conducted at least once per unit

4. Participation Grade Start with 100 points every quarter (9 wks) Points subtracted for being out of class   Unexcused absence - 10 points   Tardy- 6 points   Restroom use- 4 points   Excused absence- 2 points

5. Sample of a unit grade 1. H-work and Journals 2. Lab 3. Quizzes 4. Unit Test Total Points 100 points 30 points 20 points 50 points 200 points

6. Can you pass this class? Even if you completely fail the test with a zero you can still have a 75% on the unit Even if you completely fail the test with a zero you can still have a 75% on the unit The Semester final is worth 20% of your semester grade. Each quarter is worth 40% of your semester grade. The Semester final is worth 20% of your semester grade. Each quarter is worth 40% of your semester grade. The answer is most likely YES The answer is most likely YES

7. Test Questions (yes these will be on the final) 1. What is the goal of science? To gain knowledge about the world To gain knowledge about the world 2. Define “intelligence” Intelligence is the ability to learn from the world Intelligence is the ability to learn from the world 3. What is the absence of intelligence? Stupidity, which means the inability to learn from one’s world or situation Stupidity, which means the inability to learn from one’s world or situation

8. What’s this class about? Basically a two part course Basically a two part course Fall Semester: Chemistry Fall Semester: Chemistry Spring Semester: Physics Spring Semester: Physics Basics of “Real” Science Basics of “Real” Science

9. Fall Semester: Chemistry Scientific Method & Metric System Scientific Method & Metric System Properties of Matter Properties of Matter Atoms & Molecules Atoms & Molecules Conversions Conversions Chemical Equations Chemical Equations Chemical Reactions Chemical Reactions

10. Spring Semester: Physics Measurement and Motion Measurement and Motion Newton’s Laws Newton’s Laws Work and Energy Work and Energy Simple Machines Simple Machines Electricity and Magnetism Electricity and Magnetism Waves Waves

11. What is “Real” Science? This course will be difficult because it will challenge your reading, writing, and math skills. It is one reason why it traditionally a more challenging class. Real science uses the principles of logic and reasoning to gain knowledge about the world around us.

12. Survive and Thrive The “Bunt Brain”

14. The Scientific Method and the Metric System Unit 1

15. The Scientific Method (Organized common sense) 1. State a question or problem 2. Gather background information 3. Formulate a hypothesis 4. Conduct an experiment 5. Gather Data 6. Write a conclusion

16. 1. Question Statement Must be specific Must be specific Must be testable Must be testable

17. 2. Background Information Gathered in response to the initial question Gathered in response to the initial question Is there an answer to the question in someone else’s experiment? Is there an answer to the question in someone else’s experiment? Leads to the formation of the hypothesis Leads to the formation of the hypothesis

18. 3. Hypothesis “Educated Guess” “Educated Guess” Based on information gathered in previous experiments or researching Based on information gathered in previous experiments or researching Must be tested in the experiment to see if the “guess” was correct (its ok if you’re wrong sometimes ) Must be tested in the experiment to see if the “guess” was correct (its ok if you’re wrong sometimes )

19. 4. Experiment Based on the initial question statement Based on the initial question statement Tests the hypothesis Tests the hypothesis Gives you data Gives you data

20. 5. Results The “Data” section The “Data” section No answers to the initial question are given No answers to the initial question are given Simply lists the results of the testing done in the experiment Simply lists the results of the testing done in the experiment

21. 6. Conclusion A written statement A written statement Answers the initial question Answers the initial question Evaluates the hypothesis Evaluates the hypothesis Sometimes another question is asked and the process starts all over! Sometimes another question is asked and the process starts all over!

22. The Metric System Based on powers of 10 Based on powers of 10 Base Units with prefixes identify the magnitude (size) of the measurement Base Units with prefixes identify the magnitude (size) of the measurement

23. Prefixes K H D M D C M King Henry Died Monday Drinking Chocolate Milk Kilo, Hecto, Deca, Base, Deci, Centi, Milli Biggest          Smallest 1000, 100, 10, 1, 0.1, 0.01, 0.001

24. Converting Units (base units: gram, liter, meter) Kilo, Hecto, Deca, Base, Deci, Centi, Milli 1000, 100, 10, 1, 0.1, 0.01, 0.001 1 kilometer = 1000 meters 1 meter = 1000 millimeters 1 meter = 1/1000 kilometer 1 millimeter = 1/1000 meter

25. Dimensional Analysis Analyze the measurements and simplify 1. Find your question 2. Pick the correct conversion so that you cancel out the unit you don’t want 3. Solve the problem Example: 1,367 meters = km?
