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?"
