Students in Mrs. Jividen's class were asked to show balanced and unbalanced forces in the classroom. Some of their investigations are above. Which of the following BEST explains the results of the investigation?

• Investigations 1 and 3 demonstrate unbalanced forces since there was no movement, whereas investigations 2 and 4 demonstrate balanced forces since students caused objects to move.

• Investigations 1 and 3 demonstrate balanced forces since there was no movement, whereas investigations 2 and 4 demonstrate unbalanced forces since students caused the objects to move.

• All the investigations demonstrate balanced forces since there were students and objects involved in each investigation.

• all the investigations demonstrate unbalanced forces since of the investigations involved moving objects.

A fourth grade student wants to investigate how friction affects the motion of a ball rolling on different surfaces after rolling down a ramp. Which of the following best explains the results of the investigation?

• The ball rolling on the carpet shows a balanced force since there was less friction than when the ball rolled on the tile.

• The ball rolling on the tile shows a balanced force since there was less friction than when the ball rolled on the carpet.

• The ball rolling on the carpet shows an unbalanced force since there was less friction than when the ball rolled on the tile.

Marissa grows tow marigold plants in two hanging pots. She plants one marigold upright and she plants the other upside down, as seen in the picture above. Both marigold roots grow downward. What evidence could Marissa use to support the claim that gravitational force affects the motion of an object?

• The roots grow downward because the plants are hanging from a hook.

• The roots grow downward because they are affected by the force of gravity.

• The roots grow downward because they are trying to reach the air below the pots.

• The roots grow downward because the plants are up in the air and the roots are trying to get to the ground.
