How Meteor Size Affects the Size of CratersPhysics
Damon My topic is meteor impact. I became interested in the impact of meteors when my teacher, Mrs. Z., told me about an experiment. Things went running through my mind like, "Wow, I will get messy in this experiment," and "I would like to see how meteors and meteorites impact our moon and Earth. Mrs. Z. suggested that the question be, "Can meteor size be determined by the length of the rays and the size of the crater?" My research on meteors and meteorites uncovered that meteors are pieces of matter that get pulled in by Earth's gravity and burn up in the Earth's atmosphere. Meteorites are pieces of matter that are pulled in by Earth's gravity but don't burn up in the atmosphere. Prediction: I will be able to measure the size of the meteors and get the size of the crater. The experiment showed my prediction to be right. Materials: Lasagna pan When my investigation started, I filled a roasting pan with flour and cocoa. After I filled the pan, I dropped a golf ball in the pan. Then I measured the length of the crater and rays (the distance the debris flies). I did the same thing with large aquarium marbles, plastic marbles, and aquarium pebbles. When I finished with that, I looked through my results and added the length of each ray and the depth of the crater. I discovered that the golf ball was the object with the largest total. The smallest total of all was the aquarium pebble. The pebble test had a 7-cm. crater and didn't have a single ray! The golf ball really surprised me! It had a ray total of 179 cm.! The next question that comes to my mind that I would like to determine is, "Would the height of the distance from the mud impact the size of the crater?" Bibliography: http://www.nasa.gov
