Exploring Mixing Primary Colours Activity

Learning about Mixing Primary colours Activity using melting coloured ice blocks

Exploring Mixing Primary Colours Activity – Colours are everywhere and it is a wonderful experience for children to see how colours mix and form other colours. Mixing Primary Colours with coloured ice blocks is an opportunity for exploring colour mixing and watching how different colours blend to form other colours.

The three primary colours, red, blue and yellow are the minimum number of colours that can be mixed to make the greatest number of other colours or secondary colours.

What you will need?

Learning about primary colours

You will need ice cube trays, red, blue and yellow food colouring, warm water, 3 bowls and 7 glasses or other clear containers such as jars. We made five ice cubes of each colour and diluted the food colouring with water.

Please Note: We used warm water for our activity as it speeds up the melting process of the ice blocks. You may like to slow down the melting process by adding cold water instead.

Let’s Play

The purpose of this activity is to demonstrate to children how the primary colours: red, blue and yellow mix and form the secondary colours: green, orange, and purple.

Some Ideas:

  • Place one blue ice cube in jars 1 and 2.
  • Place one red ice cube in jars 3 and 4.
  • Place one yellow ice cube in jars 5 and 6.
  • Add one red ice cube to jar 2.
  • Add one yellow ice cube to jar 4.
  • Add one blue ice cube to jar 6.
  • Watch as the colours melt and blend together. Make predictions and talk about what is happening throughout the process. Use descriptive language.
  • Label and name each colour throughout and talk about the new colours that they see.
  • Ask questions, such as, which two colours made green? Name other objects that are green? Can you go and find me something that is green?
Mixing primary colours - what happens when we mix all 3 colours together

What happens when you add a blue, red and yellow ice block together? What colour does it make?

This is a great extension of this Mixing Primary Colours activity and explores some scientific skills. It provides an opportunity for children to exercise scientific thinking: make predictions, observations, comparison, reasoning, experimentation and evaluation.
