Checkpoint 2 Science Review

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total energy of all the particles in an object.

Front

What is an insulator?

Back

An insulator is a material that does not allow heat or electricity to pass through it easily.

Front

Which cup is the best insulator of thermal energy?

Back

The styrofoam cup is the best insulator of thermal energy.

Front

What happens to thermal energy when it is transferred?

Back

When thermal energy is transferred, it moves from a warmer object to a cooler object until both reach the same temperature.

Front

How can waves in water transfer energy?

Back

Waves in water transfer energy by moving the water particles up and down, which can cause objects on the surface to move.

Front

What type of energy does a circuit produce?

Back

A circuit can produce thermal energy and light energy.

Front

Where can oil be found?

Back

Oil can be found underground between layers of rock.

Front

What is the purpose of using a straw in the water model?

Back

Using a straw helps create waves in the water, which can demonstrate how energy is transferred.

Front

What is the effect of temperature on thermal energy?

Back

As the temperature of an object increases, its thermal energy also increases.

Front

What is the difference between conductors and insulators?

Back

Conductors allow heat and electricity to flow through them easily, while insulators do not.
