5. 11. 5E Model of Learning E – Engage E – Explore E – Explain E – Extend E – Evaluate
6. 13. What do you know about the moon?
7. 14. Graphical Dictionaries
8. 15. How big is the moon?
9. 16. How far away is the moon?
10. 17. How far?
11. 18. How are craters formed? How do you think lunar craters are formed?
12. 19. <ul><li>How does height affect crater size? </li></ul><ul><li>How does mass of impactor affect crater size? </li></ul><ul><li>How does angle of impact affect crater size? </li></ul><ul><li>How does the material of the surface affect crater size? </li></ul>Impact Craters
13. 20. <ul><li>What do you measure when you measure craters? </li></ul><ul><li>How do you measure the area of an irregular shape? </li></ul>Measuring Craters
14. 23. <ul><li>How can you measure the scale of a lunar image? </li></ul>Measuring Craters From a Distance 700 m (500 pixels)
15. 24. <ul><li>Suppose that over a period of 100,000 years, four asteroids struck the lunar surface. </li></ul><ul><li>What would be the probability that they would strike an already-cratered area, or the lunar mare, where there are few craters? </li></ul>Crater Probability
16. 25. <ul><li>What can we learn from creating our own lunar impacts? </li></ul>LCROSS
17. 26. Exploring the Moon
18. 27. Moon Math Supplemental Guide Students will: 1) approximate the area and volume of a classroom-made crater, 2) calculate and compare the scale of lunar craters to classroom craters, and 3) observe how the size, mass, and angle of impact of a projectile affect the area and volume of a crater. Moon Math: Craters!
