Slime Chemistry

Chemists study what objects are made of and how materials interact with each other. Chemists study different types of materials and try putting them together with other materials to see if a change occurs. Then chemists try to figure out what the new materials can do and brainstorm ways people can use them in their lives.

We are all chemists everyday when we cook, clean or wash our hands. Our body “does chemistry” all the time as we digest food, distribute oxygen throughout our bodies and think! Chemistry is everywhere!

The ‘Slime Chemistry’ activity at the Experiment Station exposes children to the tools, methods and questions used by chemists in order to help kids understand how these scientists find out about the world.

Discovery Center visitors are invited to “become chemists” by creating their own slime. They begin by exploring various substances, mixing them together and then studying the ‘slime-y’ result. Young chemists then can then experiment with their ‘slime’ and brainstorm possible uses for the new material in their everyday lives.

Chemistry at Home

Continue your ‘slime chemistry’ explorations at home by

Conducting your own ‘slime chemistry’ experiments

Create your own slime at home with this recipe:

1.Mix 1 cup of Elmers© White Glue and 1 cup of cold water in a bowl.

2.In a second bowl, mix 1 Tablespoon of Borax into 1 cup hot water.

3.Combine the two mixtures together with your child by stirring with a spoon or your hands. Let the slime sit for a few minutes.

4.Explore your new material by playing with it! Roll it, stretch it, cut it and have your child explain what it does!

Finding everyday chemistry in your home

You can find chemistry in action all around your home! Can you find any things in your kitchen that look different after you act upon them?

When you put bread in a toaster, does it come out the same? What is the same and different about it? Can you change it back to regular bread? Freezing water to form ice cubes is also an example of chemistry.
