Students wanted to see if the distance the marble rolled down a ramp changed the force it had. They allowed a marble to roll down the ramp from different starting points and strike a second marble. To determine if the force of the rolling marble changed, what should the students measure?
The mass of marble #2 before and after being struck by marble #1.
The distance marble #2 moves after being struck by marble #1.
The time it takes marble #2 to move after being struck by marble #1.
The direction marble #2 moves after being struck by marble #1.
Students are investigating motion with a rubber band car. They want to know how the number of winds of the rubber band affects how the car moves. They will record the number of winds of the rubber band. What other data will they need to collect?
The distance the car travels when released
The length of the rubber band during each trial
The amount of time it takes to wind the propeller
The width of the surface on which the car moves
If a student has two magnets, how might it be determined which magnet is stronger?
Count how many paper clips each magnet can lift.
Submerge each magnet in a bowl of water.
Examine each magnet to determine the north pole.
Measure the length and the mass of both magnets.
Students conducted an investigation in which they rolled a soda can down a ramp that was 30 cm high and one that was 40 cm high. Which question were the students most likely trying to answer?
How does mass of a soda can affect the distance it will roll?
How does surface friction affect the distance a soda can will roll?
How does the size of a soda can affect the distance it rolls?
How does ramp height affect the distance a soda can rolls?
Students create balloon rockets by taping drinking straws to balloons and running a thick string through the straw. The ends of the string are held tightly apart. When the balloon is inflated and released, it moves along the string. What should the student do to change the amount of friction that slows the motion of the balloon rocket?
Try different color balloons.
Use a different type of tape.
Replace the string with thin wire.
Hold the string ends closer together.
Students conducted an investigation in which they measured the distance a toy car traveled after rolling down a ramp covered with sandpaper or wax paper. Which of these questions can the students answer by analyzing the results of their investigation?

How does changing the surface of a ramp affect the distance a toy car rolls?
How does mass affect the distance a toy car moves after rolling down a ram?
How does the design of a toy car affect its movement after rolling down a ramp?
