Light and

Colour Experiment

Hands-on Science

Children learn best when they are involved in active, hands-on learning. They are naturally curious, and want to learn about themselves and the world around them. From a very young age, children engage with their world in an inquisitive way, poking, prodding, pushing, tasting, dropping, observing, and experimenting in order to learn and solve problems. It is important that we provide children with meaningful opportunities to explore their innate curiosity and sense of adventure, and encourage scientific skills such as questioning, predicting, observing, experimenting, and using the five senses to learn and understand.


It is important to engage children both physically and mentally in investigating and manipulating elements in their environment, and this exploration into light and colour provides the perfect opportunity to do just that.

You will need:

  • Betty the Yeti's Disappointing Day Picture Book

  • Several torches

  • Different coloured sections of cellophane or coloured Perspex blocks

  • Sheet of white paper

  • Betty’s World printable (click on link below)

What to do:

Step 1:

Read the story “Betty the Yeti’s Disappointing Day, making note about the lack of colour in Betty’s Arctic environment. Ask the children how they what they think about Betty’s white world and how there is no colour. Ask them what they think Betty’s world would look like with colour? How could they make this happen?


Step 2:

Show the children the torches and cellophane/Perspex blocks. Ask the children to predict what would happen if you placed one of the sheets of cellophane/Perspex blocks over the light of the torch.


Step 3:

Experiment with putting different colours over the top of the light. Experiment with how this looks on the white paper. Ask “What did you see?” “Why do you think that happened?”


Step 4:

Ask the children what will happen if they shine the torches with the colours on Betty’s white world. Experiment with this. Ask the children what they observed and if their predictions were correct.


Step 5:

Ask children to predict what will happen if you shine two torches with different colours on the same spot on the white paper. Experiment with this. Then experiment on Betty’s white world.


Step 6:

Compare the way the colours combine with the image of the Aurora Borealis at the end of the story. Ask the children if they can use the cellophane to make colours similar to the Aurora Borealis.


Step 7:

Provide the torches, cellophane/coloured Perspex blocks, white paper and Betty’s white world print out for the children to explore in their own time during free play.



Provide a lightbox/projector with Betty’s white world printable and coloured cellophane/coloured Perspex blocks for children to explore in their own way.

Colour mixing with paint- does mixing the different colours of paint have the same effect as combining the coloured cellophane over the torches?
