5th Grade Science Quarter 2 Review

Front

What is a circuit?

Back

A circuit is a closed loop that allows electricity to flow, consisting of a power source, wires, and devices like bulbs or bells.

Front

What is an LED?

Back

An LED (Light Emitting Diode) is a semiconductor device that emits light when an electric current passes through it.

Front

What happens when a switch is closed in a circuit?

Back

When a switch is closed, it completes the circuit, allowing electricity to flow and powering the devices connected to it.

Front

What is the purpose of a switch in a circuit?

Back

A switch is used to open or close a circuit, controlling the flow of electricity to the devices.

Front

What is conductivity?

Back

Conductivity is the ability of a material to allow the flow of electric current.

Front

What are insulators?

Back

Insulators are materials that do not conduct electricity well, preventing the flow of electric current.

Front

What is a battery?

Back

A battery is a device that stores chemical energy and converts it into electrical energy to power circuits.

Front

What is the role of wires in a circuit?

Back

Wires connect different components of a circuit, allowing electricity to flow between them.

Front

What is a lightbulb?

Back

A lightbulb is a device that produces light when electricity passes through it.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit where multiple paths exist for electricity to flow, allowing devices to operate independently.
