Impact Crater Lab

Impact Crater Lab. 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.

  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
