Science Experiments with Food Coloring

What is cooler than colorful, super-fun science experiments?

Probably nothing.

That’s why we always try to put as much color and fun into our science projects and experiments as we can.

The goal of science in the early years (and to some extent, through middle school), is to inspire a love of science and to encourage kids to explore the world.

Kids don’t like just reading about science, they love exploring it with their hands. Research also supports the idea that children learn better when they are engaged and lessons are hands-on.

For me as a parent, I don’t want to depend on the school system for instilling a love of science in my kids. I want my kids to love science even if the school doesn’t have the resources to give them as many hands-on science lessons as they could.

That’s why you’ll find us doing so many colorful science projects like these science experiments with food coloring at home!

And, our home support is working. Both my middle schooler and first-grader excel in science thanks to our home support.

What You Need for Food Coloring Science Projects

The number one thing that you need for science experiments with food coloring is food coloring. You can also use liquid watercolors for this if you choose to do so (liquid watercolors don’t stain as much).

For things like oobleck and semi-solid science experiments, we like to use this brand of food coloring. We’ve probably bought this set of food coloring about once a year for the past 3-4 years. That’s how much we love it!

For liquid experiments, we like to use a thinner food coloring. We like this set. It has more colors than the basic set.
