Jamie built a circuit to light a bulb. When she closed a switch, the bulb did not light, but she noticed that the wire was getting hot. When she opened the switch again, the wire cooled off. Which provides evidence that energy transfer was occurring in the circuit?

• Jamie set up the circuit to light a bulb.

• She noticed that the wire was getting hot.

• When she closed a switch, the bulb did not light, but she

Two students were experimenting with magnets during science class. Which of the following statements could be a relationship they observed? ​Select two answers.

• The greater the distance between two magnets, the weaker the force of attraction.

• One pole of a magnet is always stronger than the other pole.

• The permanent magnets were losing their magnetic properties over time.

• A magnetic field can create magnetism in a piece of iron or an iron alloy when the iron interacts with the magnetic field of a magnet.

In a parallel circuit, what would happen if one bulbs goes out?

• The rest will go out too.

• The rest will stay lit.

A student drops a book to the floor to investigate how energy changes into sound. When the book hits the floor, it makes a loud sound.

Which statement best explains how the sound was produced?

• The motion of the book falling transfers to sound when the book collides with the floor.

• The sound of the book falling transfers to sound when the book collides with the floor.

Which of the following would light a bulb?

A

• A series circuit with an open switch

• A parallel circuit with a closed switch

• A series circuit with a break in the wire.

• A parallel circuit with a wire and battery only.

Don and Annie investigate whether materials other than a steel rod and flint can be used to start a fire. They push a stick of wood against a groove in a board made of a softer type of wood, as shown in the figure. ​ ​

Which question could Jon and Ana investigate to determine whether this method can start a fire?   

• Does the stick absorb energy from the air to create a spark?

• Which question could Jon and Ana investigate to determine Does the stick create heat energy when it is pushed against the board?

• Does the stick react with the oxygen in the air to create a spark?

• Does the stick create heat and light energy when it first touches the board?
