A plate falls off the kitchen counter and makes a loud breaking noise. Which of the following statements best describes what happens?

• The moving plate makes the noise and uses energy.

• The sound is made because the plate is made of glass.

• The plate collides with the floor, and the floor makes the noise.

• The plate collides with the floor, and the energy is transferred from the moving plate to the floor and the air.

• solar panels on the roof of a house

• sunlight heating up a lake

• hearing thunder during a storm

• seeing stars in the night sky

A student is toasting bread in a toaster. Which of the following describes what is happening to the energy?

• some energy is destroyed

• thermal energy is created

• the electrical energy is transformed to thermal energy in the toaster, which toasts the bread

A vibration is

• a strong sound

• a back-and-forth motion

• a wave that transfers energy through a material and spreads outward in all directions from a vibration

Which observations are evidence that energy was transferred? Select THREE that apply.

• a girl clapped her hands, and it startled her mother

• the faucet was difficult to turn on

• a woman turned on her hair dryer, and warm air came out

• the room was dark until the boy switched on the light, and then he could see

A student is planning and carrying out an investigation about energy using a model airplane. They need a voltage source to make the propeller spin. They screw two tiny lightbulbs onto each wing, but the propeller does not turn. The student inserts a battery into the plane and connects wires from the battery to the propeller. Suddenly the propeller begins to spin. Based on the evidence of energy transfer, which item is a voltage source?

• the lightbulb

• the battery

• the airplane itself

• the wire
