Energy Review Game

Taylor is investigating sound energy by plucking stretched rubber bands. She recorded her data in the table. Which conclusion is NOT supported by the data?

• The rubber bands vibrate when plucked.

• Each of the rubber bands vibrates at the same speed.

• Shorter rubber bands vibrate faster than longer rubber bands.

• The length of the rubber band is related to the pitch produced.

Which statement correctly compares electric charge with electric current?

• They both require a human to make them.

• They both require a battery and a bulb.

• Neither require charged particles.

• They both require a movement of charged particles.

A group of students took a field trip to an old mill. They learned that old-fashioned gristmills depend on water to grind grain into flour. Water is a source of energy for a gristmill. Which statement correctly describes why this is so?

• Moving water produces wind that turns the gristmill, so it grinds the grain.

• Warm water heats the gristmill, causing it to move and grind the grain.

• Water produces electricity to turn the gristmill, so it grinds the grain.

• Moving water turns the gristmill, causing it to move and grind the grain.

Taylor gets tired of waiting for her brothers to finish playing golf. She presses on the pedal of the golf cart and it starts to move. Which of the following explains how the golf cart is able to move?

• Chemical energy stored in the battery is transformed to electrical energy which moves the cart.

• Mechanical energy from Kimberly's foot is transformed to electricity that moves the cart.

• Light energy absorbed from the Sun is transformed to electrical energy that moves the cart.

• Sound energy created by the cart is transformed to heat energy that moves the cart forward.

Olivia is experimenting with two charged objects. She holds the objects close to each other, but she makes sure they never touch. Which is the only hypothesis about the two objects that Olivia would find to be true?

• If the first object has a positive charge and if the second object has a negative charge, then the objects push away from each other.

• If both objects have a negative charge, then the objects pull toward each other.

• If the first object has a negative charge and if the second object has a positive charge, then the objects push away from each other.

• If both objects have a positive charge, then the objects push away from each other.

The picture shows a balloon after it was rubbed with wool. When the balloon touched the wall, it stayed there. What is the best explanation for the balloon staying on the wall?

• The balloon has a positive charge and the wall has a positive charge.

• The balloon has a negative charge and the wall has a negative charge.

• The balloon has a charge that is different from the charge of the wall.

• The balloon has a neutral charge and the wall has a neutral charge.
