Introduction to Science Test

A student observes that the craters on the moon are different sizes. The student designs an experiment to study the formation of craters. The materials for the experiment are marbles and a pan of flour. Which is the missing step.

Step 1.) Fill a round pan with flour.

Step 2.) Smooth out the flour in the pan.

Step. 3.) __________________________________

Step 4.) For each trial, measure the size of the crater formed and then smooth out the flour again.

• Drop the same marble from different heights into the pan of flour.

• Drop marbles of different masses from the same height into the pan.

• Drop marbles of different sizes from different heights into the pan.

• Drop a single marble one time into the pan.

A student designs an experiment to test the force of a spring launcher and four spheres with the same diameter but with different masses. What other piece of equipment would be most useful for this experiment?

• A graduated cylinder to measure the volume of each sphere

• A beaker to collect the spheres after they are launched.

• A stopwatch to measure how long it takes to lead each sphere on the spring.

• A meterstick to measure the height each sphere reaches after the sphere is launched.
