DESCRIPTION
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. - PowerPoint PPT Presentation

Impact Crater Lab
Impact Crater Lab1. Place a sheet of butcher paper on the floor and your bin of
flour in the center of the paper.2. Sprinkle a small amount of cinnamon over your flour to make
a very thin layer.3. Hold your “meteoroid” 30 cm above the surface of the flour.4. Drop the “meteoroid” into the flour.5. Measure the diameter, depth, and length of the average ray
in cm and record your data.6. Repeat 3 more times.7. Find the average of each measurment.8. Level the flour and repeat the lab for 60 cm, 90 cm, and 2 m.
Warnings!1. Do not make a mess. Be responsible.2. Do not throw your meteoroid. Gravity is the
only force that should accelerate the meteoroid.
3. Use only a small amount of cinnamon between different height trials. Do not redo the cinnamon between trials for the same height.
4. Any horseplay will result in removal from the lab.

Aristarchus Crater on Moon
Parts of the Crater
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
