Grade 8 Natural Science
Resistance of different materials and output devices
Some materials have high resistance and others have low resistance. In this lesson we will learn about how to test the resistance in different materials.

There are several different forms of light and not all can be seen with our naked eyes. In this lesson we focus on visible light and how it behaves as well as how we see different colours.
Absorption and reflection of light
Absorption and the reflection of light occur differently on surfaces. In this lesson we look at the way the eye works and why we see objects of different colours.
Refraction of light
Now that we have looked at the reflection of light where the light changes direction and is “bounced” off the surface of an object we need to look at what happens when light moves through transparent objects.
