2. “I take this oath in full understanding of the responsibility it bestows upon me.I have a monumental task ahead of me. It will take great perseverance and hard work to achieve. I will not make excuses or quit. I will not waste precious and valuable learning time.I will hustle to learn all I can in the short time I have. I will take responsibility for my actions. I will achieve my goal.I will fulfill my duties to President Obama and to Ms Hilgefort to the best of my ability. I will become an empowered global citizen. I will become a science super star. I will not settle for anything less than 80% mastery.I am smart and I am prepared to prove it to the whole world. “

3. Oh no… Security Clearance Breach!!

4. INSTRUCTIONS for each team: 1. Each table will pick a table captain—table captain will come to the front to collect materials. Table Captain is also the team writer. 2. As a team, read the introduction & study the map of the crime scene. 3. Pick 5 clues out of your envelope. 4. Using the information at hand, try to solve the crime. Do not discourage minority opinions—the team must agree on a theory. 5. Write down your hypothesis—raise your hand to have it checked. 6. Take out 3 more clues from the envelope. 7. Write another hypothesis with the 8 clues your group has now. 8. Draw 3 more clues, discuss and come to a common hypothesis. 9. Draw the last 3 clues, discuss and come to a common hypothesis for what happened, and who was probably responsible. 9. When your group has written a final (4th) hypothesis. Put your pencils and papers down and look to the front to signal completion.

5. Key things to remember: • What is a motive? • What does a hypothesis? What should it contain? • Each table will pick a table captain—table captain will come to the front to collect materials. Table Captain is also the team writer. Set up page: • Hypothesis #1: • Hypothesis #2: • Hypothesis #3: • Final Hypothesis:

6. Group discussion of hypothesis-- Type hypotheses here…

7. What aspects of this “crime scene investigation lab” were scientific? What process did your team go through? What changed your hypothesis each time?

8. Review/Discussion of Catalyst questions—would you change any of your answers now?: 1. Science is primarily concerned with understanding how the natural world works. 2. Science typically provides only temporary answers to questions. 3. Science is most concerned with collecting facts. 4. A scientific fact is absolute, fixed, and permanent. 5. A scientific theory is merely a guess. 6. Science can study and explain events that happened millions of years ago. 7. Anything done scientifically is always accurate and reliable.

9. Science is a Process Scientists ask questions about how the world works We discover pieces of the answer What we know CHANGES

10. Many ideas that were once believed to be true have since been changed.

11. It was once believed that the earth is flat.

12. And that the sun revolves around the Earth.

13. Eight Planet Solar System A few years ago, it was announced that Pluto is no longer considered a planet. Pluto is only about twice the size of its largest moon (Charon). National Geographic

14. Technology is constantly getting better and faster, which improves our methods for scientific discovery.

15. 1867: the modern typewriter

16. 1844: the telegraph

17. 1876: the telephone

18. 1944: Harvard Mark I • Linked adding machines and calculators

19. 1966: the fax machine

20. 1983: first cell phone network in the U.S.

21. 1994: the internet

22. Improving technology also gives scientists newer and stronger tools to investigate their questions.

23. Scientific Inquiry Process used by scientists Way for scientists to answer all those questions about the world

24. Scientific Inquiry Make an Observation Ask a question Construct a Hypothesis Test the Hypothesis Analyze the Data Draw a Conclusion

26. Science & The Inquiry Process (pg. 6) 8/16/11 Process scientists use to try to answer What is scientific Inquiry? questions about the world - Way to investigate how the world work Steps of Inquiry Observation Question Create hypothesis Test hypothesis Analyze Draw conclusions

27. Closing: 1. How is science a process? 2. Why is technology important to science?

28. The Great Debate: Models of Our Solar System • Look under your seat. If you have a card—stand up and come to the front of the room. • Let the show begin!

29. Ptolemy Model of the Solar System:Pg 9 Can I have 2 volunteers? Geocentric Model Geo is Greek for Earth Earth is Center of Solar System

30. Copernicus Model of the Solar System: Can I have 2 volunteers? Heliocentric Model Helios is Greek for Sun Sun is Center of Solar System

31. Galileo’s Proof of the Heliocentric Model Jupiter’s moons revolve around it! Our view of Venus from Earth changes like the phases of the moon.

32. Check for Understanding • What was the first discovery that Galileo made? Why does this suggest that the sun could be the center of the solar system? • What model of the solar system do we now know to be true?

33. Stop and Jot • Connect our last lesson on the Nature of Science with our lesson today on Solar System Theories. • From what you have seen and heard today and from what you saw in your labs the previous class, do scientific theories change over time? Why do they change over time? • Practice: • Complete the next page of your handout silently on your own.
