Some students attach a balloon to a straw and then they tape the straw to the top of a toy car. The students inflate the balloon and release the car. The car travels 40 centimeters across the floor. What should the students do to determine whether the force of the air from a balloon is enough to push the car 40 centimeters across the the same floor in repeated trials?

• Test the car several times using an identical balloon filled with different amounts of air.

• Test the car several times using different-sized balloons filled with the same amount of air.

• Test the car several times using an identical balloon filled with the same amount of air.

• Test the car several times using different-sized balloons with different amounts of air.

A student uses a spring scale to pull a 50-gram block horizontally across a wood desk. Then the student pulls the block the same distance across surfaces of carpet, sandpaper, and glass. Which question is this investigation most likely designed to answer?

• How do blocks of different sizes react to force?

• How do different surfaces affect the amount of force needed to move a block?

• How do blocks affect spring scales?

• How does the mass of a block change when it is pulled across a desk?

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. The student makes a hypothesis that the size of the craters made on the surface of the flour will depend on the height from which the marble is dropped. Some of the steps in the student's experiment are described. Which of these is most likely Step 3 in the student's experiment?

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

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

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

• Drop a single marble one at a time into the pan of flour
