Super Slime!

Ms. Anna's class continued their adventure in chemical and physical reactions with a spooky experiment; super slime!  This is an experiment most of our students have previously completed in school, but they never seem to tire of it.  

Before this experiment, we learned a couple new terms; monomer and polymer.  Check out our definitions below!

We demonstrated monomers by using legos.  Subsequently, we then linked them together to demonstrate polymers.  Before we talk about examples, I want to point out that there are two types of polymers: synthetic and natural.  An example of a synthetic polymer is gum and a natural polymer we all have in our bodies is muscle.  

The polymer in this experiment is our glue.  It holds together the water, borax, and food coloring.  Check out our video below!

After we completed the experiment it was time to let the kids have a go!  They love helping me in the classroom and trying things out.

Then it was time for the best part; testing the viscosity of our slime!  I asked the students if they thought this reaction was chemical or physical.  It's physical!  Why?  That's due to the molecules linking together to form new ones.  The slime cannot be reverted back to its original mixture of borax, glue and water.

Thanks for checking out our slime experiment.  Stay tuned for more adventures in STEAM!

Full S.T.E.A.M. Ahead!
