Colour mixing with food colouring and water

Colour mixing is a great activity for learning about primary and secondary colours as well as fantastic fine motor control practice if children use a dropper or pipette. Once children have made secondary colours they could then experiment by mixing primary and secondary colours to make tertiary colours or try to make as many different shades of one colour as they can.

Materials

Water

Beakers

Food colouring

Pipettes or droppers

Instructions

Add a small amount of red, yellow and blue food colouring to separate beakers and then top up with a little water.

Use the pipettes or droppers to drop different colours of water onto a plastic plate and record which new colours are created.

Colour Mixing

Why does this work?

Primary colours cannot be created by mixing other colours together. These are:

Red, Yellow and Blue

Secondary colours are made by mixing primary colours.

Yellow + Blue = Green

Red + Yellow = Orange

Blue + Red = Purple

Tertiary colours are made by mixing a primary colour with a secondary colour.

Questions to ask

What do you think would happen if you used a paper plate instead of a plastic plate?

Do you think the colours would still mix if you used filter paper or kitchen roll?

Which colours do you think are warm and which cold colours?
