1. Impact Crater Lab

2. Impact Crater Lab
Place a sheet of butcher paper on the floor and your bin of flour in the center of the paper.
Sprinkle a small amount of cinnamon over your flour to make a very thin layer.
Hold your “meteoroid” 30 cm above the surface of the flour.
Drop the “meteoroid” into the flour.
Measure the diameter, depth, and length of the average ray in cm and record your data.
Repeat 3 more times.
Find the average of each measurment.
Level the flour and repeat the lab for 60 cm, 90 cm, and 2 m.

3. Warnings! Do not make a mess. Be responsible.
Do not throw your meteoroid. Gravity is the only force that should accelerate the meteoroid.
Use only a small amount of cinnamon between different height trials. Do not redo the cinnamon between trials for the same height.
Any horseplay will result in removal from the lab.

17. Impact Crater Vocabulary
Floor: The bowl shaped or flat area
Central Uplift: Mountains formed due to the increase and rapid decrease in pressure during an impact
Wall: steep sides of the crater area
Raised Rim: Rock thrown out of the crater and deposited in a ring-shaped pile at the crater's edge during an impact
Ejecta: blanket of material surrounding the crater that is thrown out during the impact
Rays: The bright streaks starting from a crater and extending away for great distances
