6th Grade Science Unit 2- Energy

Front

What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, such as kinetic, potential, thermal, and chemical energy.

Front

What is heat energy?

Back

Heat energy is a form of energy that is transferred between objects due to a temperature difference. It flows from warmer objects to cooler ones.

Front

What is the difference between conduction, convection, and radiation?

Back

Conduction is the transfer of heat through direct contact, convection is the transfer of heat through fluids (liquids and gases), and radiation is the transfer of heat through electromagnetic waves.

Front

What is a circuit?

Back

A circuit is a closed loop that allows electricity to flow. It typically includes a power source, conductors, and a load (like a light bulb).

Front

What is a complete circuit?

Back

A complete circuit is one where the electrical path is unbroken, allowing current to flow and power devices like light bulbs.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily. Examples include rubber, glass, and plastic.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily. Examples include metals like copper and silver.

Front

What is solar energy?

Back

Solar energy is energy from the sun that can be converted into thermal or electrical energy using solar panels or solar heaters.

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 and allowing devices to be turned on or off.

Front

What happens when a circuit is broken?

Back

When a circuit is broken, the flow of electricity stops, and devices connected to the circuit will not work.
