4th Grade Twig Science Module 2 Energy

Front

What is energy?

Back

Energy is the ability to do work or cause change. It can exist in different forms, such as light, heat, and motion.

Front

What is a transfer of energy?

Back

A transfer of energy occurs when energy moves from one object or system to another, such as when heat moves from a hot object to a cooler one.

Front

What is solar energy?

Back

Solar energy is the energy that comes from the sun. It can be used to heat things or generate electricity.

Front

What is artificial light?

Back

Artificial light is light that is made by humans, such as light from light bulbs or candles, rather than from natural sources like the sun.

Front

What is the difference between renewable and non-renewable energy?

Back

Renewable energy comes from sources that can be replenished, like wind and solar, while non-renewable energy comes from sources that can run out, like coal and oil.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion. Anything that is moving has kinetic energy.

Front

What is potential energy?

Back

Potential energy is stored energy that has the potential to do work. For example, a ball held at a height has potential energy.

Front

What is heat energy?

Back

Heat energy is the energy that comes from the temperature of matter. It is the energy that causes things to feel warm or hot.

Front

What is a conductor?

Back

A conductor is a material that allows energy, especially heat or electricity, to pass through it easily, like metals.

Front

What is an insulator?

Back

An insulator is a material that does not allow energy, especially heat or electricity, to pass through it easily, like rubber or wood.
