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

Juju.01) 5 geologic events a group of students designed an experiment in an ice rink to represent the solar system. the steps of the experiment are listed below. 5: geologic events 1. choose a student to represent the sun. the planets are represented by two tennis balls. 2. ask the student to hold the tennis balls in each palm and spin on the ice with arms stretched out. 3. ask the student to draw in the arms after about 10 spins. 4. observe the student's arms rotate faster when they are closer to the body. 05 geologic events enors) the experiment most likely demonstrates that (2 points) 07 discussion-based sessment/module planets exert gravitational force on the sun the sun exerts gravitational force on the planets 3.07 discussion-based ssessment speed of a planet depends on its distance from the sun new version available!
