Tina made a snack mix using popcorn, pretzels, and chocolate pieces.
The picture shows Tina’s snack mix.

Before eating, Tina picked out all the chocolate pieces because she didn’t want them.
What does this tell us about her snack mix?

• It was made by heating the ingredients together to form something new. This was a chemical change.

• It was a mixture, and the parts could be picked out by hand. This was a physical change.

• It turned into a solid, so the parts stuck together permanently.

• It caused a reaction that changed the popcorn.

Ethan left a bowl of ice cream on the kitchen counter while he went to take a phone call.
When he came back, the ice cream had turned into a liquid.
Ethan says this happened because of the room temperature.

Which argument best supports Ethan’s claim?

• The air in the room was colder than the freezer and caused the ice cream to freeze.

• The bowl was too small, so the ice cream lost its flavor.

• The room was warmer than the ice cream and caused it to melt.

• The ice cream evaporated because it was in the sun.

A student connects a battery, wires, a light bulb, and a switch to make an electric circuit.
When the switch is closed, the light bulb turns on. When the switch is open, the light bulb turns off.

What does this tell us about the role of the switch in the circuit?

• The switch makes the battery last longer by using less energy.

• The switch changes the amount of electricity going to the light bulb.

• The switch opens and closes the circuit to control the flow of electricity.

• The switch helps the wires stay connected to the light bulb.
