Why Try Slime Science Experiments?

Most kids really love slime. Its sticky, messy, and tons of fun to play with.

One of my favorite things to do in the science classroom is to take something that a child loves (in this case, slime) and then explore the science behind it.

We’ve also used slime to illustrate other scientific concepts, because things are just more fun with slime!

Giving kids a chance to explore science in a framework of something they love allows them to develop a love of science that will sustain them even when things get boring in high school or college.

Trying these slime science experiments will help kids establish a lifelong love of science!
