1. Students placed two sets of identical magnets near each other, as shown in the Before diagram. The After diagram shows that the magnets in the first set moved toward each other. The magnets in the second set did not move toward each other. Which statement best explains the behavior of one of these sets of magnets?

• The magnets in the first set moved toward each other because the opposite poles of the magnets attracted each other.

• The magnets in the second set did not move toward each other because the distance between the magnets was too large.

• The magnets in the first set moved toward each other because the north pole of each magnet was stronger than its south pole.

• The magnets in the second set did not move toward each other because these magnets need electricity to work.

8. A student has four blocks made of the same type of solid wood. The student measured and recorded the mass of each block. Then the student made some predictions about Block C. Which three predictions are best supported by the models?

• The mass of Block C is 3 grams.

• The length of Block C is 3 centimeters.

13. A student builds a circuit with a fan, a battery, and some wire. The battery is being drained to quickly. Which of these should the student add to the circuit so the battery drains more slowly?

• a switch, so the fan can be turned on and off

• a light bulb, to show when the battery is getting low

• a different battery that provides less energy

• a different fan that requires more power

15. A student rolls a ball down a ramp that has a toy car sitting at the bottom. The ball hits the car at the bottom. The car rolls off the ramp and onto the floor. The student wants to make the car roll farther and faster. In which of these ways can the student give the car more energy?

• Use a different ball that weighs less.

• Tape a small weight to the top of the car so it is heavier.

• Use a taller ramp that raises the ball higher off the ground.

• Make the bottom of the ramp longer so the ball has to roll farther before hitting the car.
