1. describe how impact craters are formed when a comet or asteroid hits Earth
based on a simulation; and
2. present observations on simulating a comet or asteroid impact using
drawings.
Materials Needed:
1 rectangular container (aluminum tray or plastic)
1 pebble (1-4 cm in diameter)
colored flour/colored starch
pencil
Procedure:
1. Fill the rectangular tray with colored flour about 3-4 centimeters deep.
2. Place the tray on top of a table (or arm rest of a chair).
3. Throw a pebble to hit the flour in the tray. Do this about four times, hitting
different parts of the flour in the tray.
4. On the space below, draw the shape of the “craters” made by the pebble on the
colored flour as:
