Earth 2.2 Minilab Craters Procedure: names_______________________________________ Period _______ Date _________ 1. Place flour – the amount given by Mrs. Dennis – in your dish and carefully even it out. 2. Shake cocoa in a thin layer over the flour either by sprinkling with a spoon or using a sieve. 3. Carefully carry the dish outside as directed. Place the dish on the ground or sidewalk where it is level. 4. Take one rock or piece of gravel. Holding it knee-high over the dish, simply drop it into the dish. On the back of this paper, RECORD your observations, including a sketch (or send a picture) of the crater and its rays. 5. Carefully remove the rock. Holding it knee-high, toss it into the dish at an angle, trying to hit a different spot than the first crater. On the back of this paper, RECORD your observations, including a sketch (or send a picture) of the crater and its rays. 6. Dump your used flour & cocoa into the garbage bag before returning the dish and rock. Wait for Mrs. Dennis’ instructions to go back to the classroom. Questions: 1. List at least 2 differences between the 2 craters. 2. Which drop or throw do you think is more realistic of how craters on the moon were formed? Why?
