Oil and Water experiment

Sweet Pea concentrating on getting water in his dropper

We’ve had a lot of rain here lately and the boys were getting a little antsy. I pulled out the water and oil, taking a tip from Growing a Jeweled Rose, added some food coloring to the water and set it out along with a couple of medicine droppers. The boys, of course, were immediately drawn to it asking if it was for them!

This is a great activity for fine motor pincer grasp work, learning/reviewing colors, science talk about liquids.

Isn’t this cool?!

It’s pretty self-explanatory what to do. Pick up drops of colored water and drop them into the thin coat of oil (preferably in a dish with sides).

Hint: I found medicine cups to be the perfect size for holding paints and water for their projects!

When the water came into contact with the oil it formed little droplets, which alone looked pretty neat. Here are some questions to ask while you do this experiment:

What happens to the drops of color?
Does it stay in little droplets? Why?
What happens when you try to make two droplets into one? How do you do that?
What happens to the color when they are mixed?

I hope you have fun with this experiment! Tomorrow I’ll share with how we switched things up a bit the next time we pulled out the oil!
