Light travels in straight lines through empty space. If it hits an object some of it is reflected back and the rest is absorbed by the object. It is this reflection of light that allows us to see objects around us. The walls, tables and chairs in your room don’t emit their own light, you…
I’ve lost count of the number of water science experiments we’ve done over the years. Water is pretty amazing. Did you know it is the only natural substance to exist in three physical states at temperatures naturally occurring on Earth? Facts about Water Water has lots of properties that make it just brilliant for simple…
Visible or white light is made up of a range of colours each with a different wavelength. One way to see the different colours is to use a prism to split the light. When white light enters the prism it slows down and changes direction. The amount the light changes depends on the wavelength. Red…
