ACP SCIENCE PRACTICE REVIEW #1

Front

What is a circuit?

Back

A circuit is a closed path through which electric current flows.

Front

What is a series circuit?

Back

A series circuit is a type of circuit where the components are connected end-to-end, so the current flows through each component one after the other.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit where the components are connected across common points or junctions, allowing current to flow through multiple paths.

Front

What does it mean when light is reflecting?

Back

Reflecting means that light bounces off a surface instead of passing through it.

Front

What does it mean when light is refracting?

Back

Refracting means that light bends as it passes from one medium to another, changing its speed.

Front

What is thermal insulation?

Back

Thermal insulation is a material that reduces the transfer of heat, helping to keep things hot or cold.

Front

What is the purpose of aluminum foil in keeping food hot?

Back

Aluminum foil reflects heat back towards the food, helping to keep it warm.

Front

What is a switch in a circuit?

Back

A switch is a device that can open or close a circuit, controlling the flow of electricity.

Front

What happens if a switch is open?

Back

If a switch is open, the circuit is incomplete, and electricity cannot flow, so devices like light bulbs will not work.

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to power the circuit.
