Daniel is playing pool. The diagram shows two balls on the pool table.

To get the 3-ball to fall into the corner pocket of the pool table:

Daniel uses the pool stick to push the white ball in the direction of the 3-ball.

The white ball makes contact with the 3-ball.

The 3-ball rolls toward the corner pocket of the pool table.

Daniel sees that the 3-ball stops before it goes in the pocket. What should he do differently next time to get the 3-ball to go into the pocket?

• He should push the white ball with more energy.

• He should move the white ball further away from the 3-ball.

• He should push the white ball in a different direction.

• He should push the white ball with less energy.

Daniel uses the pool stick to push the white ball in the direction of the 3-ball.

The white ball makes contact with the 3-ball.

The 3-ball rolls toward the corner pocket of the pool table.

Daniel measures the distance from the 3-ball to the corner pocket. His friend uses a stopwatch to measure how long it takes from when the 3-ball is hit until it goes in the pocket. What question are they trying to answer?

• What is the energy of the 3-ball after the collision?

• What is the speed of the 3-ball after the collision?

• What is the energy of the white ball before the collision?

• What is the speed of the white ball before the collision?

Alexa wanted to make a solar oven. A solar oven uses energy from the sun to cook food. When food is placed in the box, the sun’s energy reflecting off the aluminum foil helps heat the food.

To make the oven, Alexa could only use materials she did not need to buy. To be useful, the oven needs to get very hot. She used the diagram as a model for the oven she would make.

Alexa investigated liner materials and put her data in a table.

Material A 38 degrees

Material B 40 degrees

Material C 49 degrees

Why did Alexa choose Material C as the oven liner?

• Material C met the constraint of raising the temperature fastest.

• Material C met the constraint of not having to buy it.

• Material C met the criteria of raising the temperature fastest.

• Material C met the criteria of not having to buy it.

Cora has a clap light on her desk. She likes to use it to turn the light on while in bed. Select the correct answer. Cora observes that the clap light doesn’t work when she is behind the microphone. How can she change the design so that she can use the clap light from everywhere in the room?

• Move the microphone closer to the lamp.

• Use a device with a microphone on all sides.

• Use a brighter light bulb in the lamp.

• Unplug the microphone when it is not in use.

Ryan holds on to the railing as he climbs the school steps to get into the building. It’s a cold day, and Ryan does not have gloves with him. Ryan observes that when he touches the metal on the railing, it feels colder than the cloth of his backpack. Ryan does not understand how this is possible, so he decides to perform an investigation. He places his hands on two different objects at a time to determine which feels cooler.

Which question is Ryan most likely able to answer with this investigation?

• How cold are the objects?

• How do materials compare in how cool they feel?

• Why didn't my backpack feel cold?

• Why did the railing feel cold?

Look at the picture.

The answer to which question provides evidence that can help predict the outcome of the collision?

• What is the temperature of each ball?

• How much motion energy is transformed to sound energy?

• What is the speed of each ball?

• How much total kinetic energy is lost as heat?

Mia is investigating energy in collisions. She is using a large rubber band to push a toy car into a large wooden block.

For which claim will Mia’s investigation most likely provide evidence?

• A toy car needs electricity to move a block.

• When toy cars travel, they always go the same distance and in the same direction.

• When objects collide, they push on one another and can change motion.

• The speed of a toy car is the same for every trial.
