Description

Experiment with the properties of light by moving around light sources, mirrors and other objects after a short introduction on reflection, refraction, opaque materials, transparent materials, and translucent materials. The goal is to get the light from its source to a cat!

Instructions

Play through this interactive game to learn about Electromagnetic Radiation. Suitable for Grade 3, Grade 4, Grade 5.

Main Concepts

Some objects, such as the sun or a flashlight, emit light.

Light rays typically travel in a straight line until they strike an object.

When light travels from one medium to another, it can bend and change directions; this is called refraction.

Water and prisms can cause light to bend, or refract, when it passes through them.

Mirrors and other shiny surfaces reflect beams of light, causing light to bounce off of them in a different direction.

Light cannot pass through an opaque material.

When light passes through a translucent material, the images on the other side are blurry.

Light can pass straight through a transparent material.

Discussion Questions

Before the Game

In this game you will learn about light. What do we use light for today? What types of objects emit light? What happens when you turn a flashlight on at night? What happens if someone stands in front of the flashlight as you shine it? How is a beam of light affected by a mirror? How is it affected by a glass of water?

After the Game

What does it mean for a surface to be opaque? What happened when you shined the light onto the opaque surface? Name something that would be a transparent surface? How were you able to use the mirrors to get the light beam to the cat?
