simulate the impacts of asteroids and comets on Earth; and • present observations on simulating the impacts of asteroids and comets using drawing/ illustrations. Materials: old newspaper, pan/tray/any container with flat surface, rocks of different sizes (small, medium, and large), sand, ruler Procedures: 1. Lay the old newspaper on the floor. 2. Put the container in the center of the old newspaper. 3. Fill the tray 10 centimeters high with sand. 4. Measure the diameter of all three rocks in centimeters (cm). Rock 1 is ____ cm Rock 2 is ____ cm Rock 3 is____ cm 5. Drop the first rock from the first height. 6. Remove the rock carefully and draw the shape of the “crater” made by the rock on the sand in the chart. 7. Repeat procedure for the next height. 8. Repeat procedure for the next impactor. Table 1. Crater-making Rock Diameter Height Crater drawing Rock 1= ____ cm 1st throw 30 cm 2nd throw 60 cm Rock 2= ____ cm 1st throw 30 cm 2nd throw 60 cm​
