Question 7

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?

Accepted Answer

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

Answer

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

Answer

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

Answer

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

Question 8

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?

Accepted Answer

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

Answer

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

Answer

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

Answer

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

Question 9

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?

Accepted Answer

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

Answer

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.

Answer

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

Answer

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.

Question 10

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?

Accepted Answer

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

Answer

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

Answer

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

Answer

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

Question 11

Travis is making this chart of examples of actions in which energy has caused change, as shown below. He accidentally added one that should NOT have been listed. Which action should Travis have left off his chart?

Accepted Answer

holding a cup

Answer

dropping a book

Answer

rolling a ball

Answer

opening a door

Question 12

Students want to replace the material that connects the battery and the bulb in the circuit. Which material would be the best choice?

Accepted Answer

Copper, because it is a conductor.

Answer

String, because it is flexible.

Answer

Plastic, because it is an insulator.

Answer

Glass, because light energy can move through it.

Question 13

At noon on a sunny day, Taylor walks barefoot down the street to her friend's house. The pavement is so hot she can barely stand it. After dark, she walks back home and notices that the pavement is much cooler. Which of the following explains why this happened?

Accepted Answer

The pavement lost some of its heat after the Sun went down.

Answer

The heat moved down through the pavement into the soil.

Answer

Taylor's feet got used to walking around on the hot pavement.

Answer

The water in the pavement absorbed the heat and evaporated.

Question 14

Olivia rides her bike to and from school. Sophia's bike has a special tape that reflects energy from the sun to make it easier for cars to see her. She also uses a bell to let other bikers know if she is going to move pass them. Which of the following form of energy does Olivia not use when biking?

Accepted Answer

electrical energy

Answer

mechanical energy

Answer

sound energy

Answer

light energy

Question 15

Students set up the circuit pictured below. How will this circuit need to be changed so that currents can flow from the battery to light the bulb?

Accepted Answer

Close the switch.

Answer

Add one more battery.

Answer

Increase the amount of wire used.

Answer

Place the bulb closer to the battery.

Question 16

Students are experimenting with a simple circuit. They notice that the bulb glows brighter when they add another battery to the circuit. Which statement correctly explains this observation?
