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.
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
- 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
Fill the cups or bowls with 2 oz of water. I used 2 empty vases that never get used in out house.
Add 1 drop of food colour. Stir the food colouring with a stick or spoon so that the colour is nicely mixed.
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.
Don’t forget to check out what the other Playful Preschool bloggers came up with for the rainbow theme. Thanks for walking with me.
