Science B3 S1 Test Review

Students built an electrical circuit like the one shown in the diagram. Which of the following explains what happens when the light bulb lights up? When the switch is closed–

• energy moves through the wires and is changed into light energy in the bulb.

• the bulb reflects sunlight until it shines brightly and makes heat energy.

• the physical properties of the battery are changed by the chemicals inside it.

• the wires that connect the parts stop heat energy from flowing.

Students are using a hand-held generator to produce light energy. The light only lights up when the handle is turned. What can the students do to change the amount of energy that enters the bulb?

• Place a filter over the light bulb.

• Turn the handle at different speeds.

• Change the handle to a smaller one.

• Use a different bulb.

Which of the following is evidence that electrical energy can be moved from place to place? Power plants that make electricity–

• cost quite a bit of money to build and run.

• are often very far from the places that receive the electricity.

• sometimes use moving water to make electricity.

• need people and materials in order to make electricity.

The illustration below shows a lamp that is plugged into an electrical outlet. When the lamp is turned on and the bulb is lit, it shows that electrical energy–

• moves in straight lines.

• is produced by moving water.

• can be changed into light energy.

• is the fastest moving form of energy.

Which of the following provides evidence that light energy can move from place to place?

• A flashlight turns on when the switch is moved.

• A light bulb gets hot when it is left on for a while.

• The deepest parts of the ocean are very dark.

• Very distant stars can be seen in the night sky.

Why does a fan spin when you plug it into an electrical outlet?

• The air makes the fan spin.

• Electrical energy is changed into mechanical energy.

• The fan uses its own energy to spin.

• Heat energy makes the fan spin.

Which part of an electrical circuit can stop the energy from moving?

• The wires

• The battery

• The light bulb

• The switch

A child pushes a toy car with a battery inside. When the car moves and the lights on the car turn on, what is happening?

• Energy from the battery changes into motion and light energy.

• The wheels create energy to power the lights.

• The car makes energy from sunlight.

• The energy in the battery is being stored and not used.
