1. A group of students did an experiment to find out if the
angle of impact affects the size of crater formed. They
filled a basin with flour, covered the surface with cocoa, and
dropped marbles along a 100 cm ramp. They recorded the
size of the craters. Look at their data table.

Based on this data, what can students conclude about the effect of drop-angle on the
size of crater formed?
Mark the one best answer)
A The larger the angle the smaller the crater.
OB The larger the angle the larger the crater.
C The angle does not make much difference in crater size
D There is not enough data to draw a conclusion
