Science CCA #5 Review

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, causing objects to appear distorted or displaced.

Front

What do prisms do to light?

Back

Prisms refract light, separating it into its component colors (spectrum) when light passes through.

Front

What is the purpose of a magnifying glass?

Back

A magnifying glass uses refraction to enlarge the appearance of objects, making them easier to see.

Front

What happens to solar panels at night?

Back

Solar panels lose heat and stop generating electricity when there is no sunlight.

Front

What is the relationship between density and floating?

Back

An object will float in water if its density is less than that of water (1 gram per cubic centimeter).

Front

How do solar cells work?

Back

Solar cells convert light energy from the sun into electrical energy.

Front

What is the volume of an object?

Back

The volume is the amount of space an object occupies, often measured in milliliters (ml) or cubic centimeters (cm³).

Front

How do you measure the volume of an irregular object?

Back

You can measure the volume of an irregular object by submerging it in water and measuring the water displacement.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons, which can be converted into other forms of energy, such as light.

Front

What is an example of an object that converts electrical energy into light energy?

Back

A lamp is an example of an object that converts electrical energy into light energy.
