A group of students is investigating the effects of force when brushing teeth. The students used hard-boiled eggs to represent teeth, the same toothbrush, the same brand of toothpaste, and the same amount of water.
Which hypothesis could be tested in this investigation?
A.Brushing teeth for longer amounts of time will damage teeth.
B.Gently brushing teeth will cause less damage to teeth.
C.Using more toothpaste will cause less damage to teeth.
D.Smaller toothbrushes clean teeth better than larger toothbrushes.

Students design an experiment to determine how much force is needed to move blocks of wood of different masses slowly across a lab table.
Which procedure should students include in their design?
A. Conduct five trials, using a different scale to pull each block of wood
B. Conduct five trials, pulling a different side of each block each time
C. Conduct five trials, using a different table for each trial
D. Conduct five trials, pulling each block of wood in the same way for each trial

A group of students were designing a tabletop bumper car model to test the effects of different forces. They used several of the same toy cars to represent the bumper cars and a cardboard box to represent the bumper car arena. They used a rubber mat, a plastic folder, and paper towel to line the bottom of the box.
Which question is this investigation most likely designed to answer?
A.How does the amount of force affect how many bumper cars will get hit?
B.How does the size of the car affect how much force is needed to move it?
C.How does the material on the bottom of the box affect how far the cars will move?
D.How does the amount of force affect how long the cars will continue to move?

Four different students take turns pushing a large, heavy ball on the school parking lot. What is the best way to determine which student used the most force to push the ball?
A.compare the sizes of the students
B.compare the ages of the students
C.compare the distances that the ball rolled
D.compare the number of times the ball was rolled

Picking up a heavy box is much more difficult than putting it down. What is a likely explanation for this?
A.Pushing force is more difficult to accomplish than pulling force.
B.The force of gravity acts against you when you try to push something to the ground.
C.The action is less difficult because nothing is pulling the object toward the ground.
D.The force of gravity is pulling the box toward the ground which makes the action of putting the box down easier to do.

Two students sit on a seesaw in a way that makes it balance and not move. When a third person pushes down on one side, that side moves down. What caused the seesaw to move?
A.The effect of gravity increased when one side was pushed d
B.The friction between the two sides decreased because of the push.
C.The total force increased on the side that was pushed down.
D.The push on one side of the seesaw decreased the force on the other side.

Two students designed an experiment to test the effects of force on an object. They stood on opposite sides of a large box and then they each applied a push to the box. The box moved to the right.
What can be said about the effect of the force being applied by the above student on the left?
A.The force of magnetism was greater on the left so the box moved to the right.
B.The pull of gravity was greater on the right so the box moved to the right.
C.The pushing force was greater on the left so the box moved to the right.
D.The force of friction was less on the left so the box moved to the right.
