METEORITE HOLE DATA

For Further Investigation
Since meteoroids come from different celestial bodies, they are made of different materials. Iron meteorites contain about 90 percent iron and are almost three times as heavy as stony meteorites. Do heavier meteorites make bigger holes? A project question might be, How would the composition of a meteorite affect the size of its impact crater?
Clues for Your Investigation
- Demonstrate the difference in the impact of a heavier meteorite by repeating the experiment using a heavier piece of clay. Make a second clay ball the same size as the first, but make it heavier by wrapping the clay around three to four metal washers. Be sure to drop the second clay ball from the same height as the first. Use a different color pen to mark the results on the toothpick. Compare the depth of the impact holes of the two types of meteorites.
- Photograph the sand before and after impact. Display the photos to represent the results.
