Colourful Discoveries

A selection of science experiments and activities to do at home or school all about colour.

• Colours in Nature- Nature is full of wonderful colours. Take a walk or explore your garden with the colour viewer to see if you can find something to match each colour.
• Spectroscopes-Learn how to build a spectroscope and investigate what colours make up light
• Density Rainbow-Experiment with Density and create your own rainbow in a jar
• Acids and Alkalis- Make your own red cabbage indicator and investigate acids and alkalis with items from your kitchen.
• Chromatography- Chromatography is used by scientists to separate mixtures to see what they are made of. We can use chromatography to see what colours are in the ink inside our pens. Although the lid on your pen might be black or blue or pink the ink inside is actually made up of lots of different colours. Have a go at home and see what colour ink your pens are made of.
• Mixing Colours- There are millions of colours in the world. We can mix red, blue, and yellow paint to make every colour of the rainbow. It’s a little bit different when we are mixing light. The light that comes from the sun or other sources such as lightbulbs is called white light. We can mix three different coloured lights to make white light. Are they the same as the paint colours we mix?
• Colour Hunt- There are colours all around us. Roll the colour dice and let’s see how many coloured objects we can find in our houses. Can you make your colourful objects into a picture?
