Objective
By the end of this lesson, you will be able to mix primary colors to create a rainbow using a fun science experiment.
Materials and Prep
3 clear cups
Water
Red, blue, and yellow food colouring
Spoon for stirring
Paper towels for cleanup
No prior knowledge is needed for this lesson, just come ready to have fun!
Activities
Rainbow Mixing: Fill each cup with water and add a few drops of red, blue, and yellow food colouring to each cup. Stir each cup and observe how the colours mix together to create new colours.
Colour Exploration: Experiment with different ratios of colours in the cups to see how it affects the final colour outcome.
Rainbow Creation: Once you have mixed the colours, try pouring them together in a clear container to see the rainbow effect.
Talking Points
- Introduction: "Today, we are going to learn how to mix primary colours to create a rainbow. Primary colours are red, blue, and yellow."
- Colour Mixing: "When we mix red and blue, we get purple. When we mix blue and yellow, we get green. When we mix red and yellow, we get orange."
- Observations: "What do you notice when you mix the colours together? How do the colours change?"
- Experimentation: "Try mixing different amounts of colours. What happens when you add more red? What about more blue?"
- Conclusion: "Now you know how to mix primary colors to create a rainbow. What was your favorite part of the experiment?"
