Making Our Own Moon Craters
Today we looked closely at photos of craters on the moon and the Earth. We recorded our observations. Next we did an experiment called 'Making Our Own Moon Craters'. We filled a pan with bout 5 cm of flour. Next we added a tablespoon of cocoa and mixed this to look like the surface of the moon.. We smoothed out the flour with our hand to create a flat surface. Next we held a marble about 5 cm above the flour and
released it .
We observed what happened and
recorded this on a chart. We n explored different impactor sizes,
weights, distances dropped, or angles of impact. Each group then conducted
an experiment by changing one variable to
see how it affects impact crater size.
Group 1 used different
impactor sizes
Group 2 used different weights
Group 3 used different
distances
Group 4 used different angles
We recorded
our results and reported our findings to the class. These
findings were recorded on a chart and written up on a class chart.
