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 covers about 70% of the surface of the Earth. Water expands…
The ocean looks blue because of how it absorbs sunlight. Water absorbs the longer wavelength colours at the red end of the light spectrum and the short wavelength violet and ultraviolet light. Blue light is absorbed the least and is scattered and reflected back into our eyes, which makes the ocean look blue. The actual…

Light is actually made up of a spectrum of colours each with a different frequency. One way to see the spectrum of colours is to use a prism to split the light. What is a prism? A prism is a triangular block of glass or perspex which splits light into its constituent colours. When light…
Do you know why the sky looks blue? Light from the sun is made up of all the colours of the rainbow. A rainbow in the sky is formed when sunlight is refracted and dispersed in drops of rain or mist which splits the white light into its constituent colours. Red light has the longest…
Do you think of cows and global warming in the same sentence? Most people think of carbon dioxide being the most troublesome greenhouse gas, but actually methane is the more damaging of the two as it traps much more heat than carbon dioxide. Methane pollution is thought to cause around a quarter of the global…
We’ve all heard about climate change, but what is it and how can we teach our children about it? First children need to be informed and secondly they need to feel empowered, to feel like they can make a difference. Remember lots of small actions add up to a big result. What is Climate? Climate…
