Who’s up for some rainbow science for preschoolers?
Today for #PlayfulPreschool, I will be sharing with you one of our fun preschool science experiments that my daughter J thinks is the most awesome thing in the world. To be honest, as long as something happens in our experiments, she thinks it pretty awesome.
With Spring and St Patrick’s Day coming up, I decided to see if I could make the colours of the rainbow (well a few of them at least) disappear.
Rainbow Science for Preschoolers:
Disappearing Rainbow Colours
Here is a quick background on why we chose this rainbow science for preschoolers experiment. J is a very curious little person. Recently I was scrubbbing a pot that I accidentally forgot on the stove and sadly baking soda and vinegar was not doing the job. I decided to open my windows (in -20C weather) and try to use some bleach.
J immediately said, “Mommy, what’s that smell?” I replied and said it was bleach and I am using it to get rid of this lovely stain of black on my pot. Then an idea popped up. If the bleach can get rid of the black stain, what can it do for other colours?
What You Need for Your Rainbow Science for Preschoolers Experiment
1 cup of bleach
water
3 primary colours food colouring
4 or 5 small bowls or cups that are clear
a well ventilated area
Steps of the Rainbow Science
for Preschoolers Experiment
Step 1:
Fill the cups or bowls with  2 oz of water. I used 2 empty vases that never get used in out house.
Step 2:
Add 1 drop of food colour. Stir the food colouring with a stick or spoon so that the colour is nicely mixed.
Step 3:
Add 1/4 cup of bleach to the food-coloured water.
Step 4 of the Rainbow Science for Preschoolers
Observe any changes.
If done correctly, the liquid in the cup or bowl should be completely clear when the bleach is added.
This is a great idea, I hadn’t thought of using bleach for kids science but I’m sure mine would be really interested to see this disappering colours transformation too – very cool
Great way to take your daughter’s question and turn it into something that she will remember. Smells are certainly a strong memory trigger so I am sure this will stick in her mind for quite some time.
[…] perhaps you may want to try this experiment that is my daughter’s favourite to date: DISAPPEARING RAINBOW COLOURS where we actually make the colours […]

I love when we take real life questions and investigate them to learn more!
Kim says
That is so cool! I’m sure the kids were amazed!
Amanda says
What a creative way to teach about colors. My boys love any and all science experiments. Pinning this so we remember to try it!
