How are shadows made and can one object have two shadows? Do all materials make shadows or can some let the light pass through? We also look at astounding ways to mix and separate colours. Plus we create our very own rainbow on the ceiling!
In the sound section we use different everyday items to create some amazing sounds. We see how to make sounds louder, quieter, higher or lower. We hear how our voices can be transformed into a high squeaky mouse, or a large, low elephant!
