Slimy Science!!

I just LOVE it when science creates BIG REACTIONS from the kids! 

We did an experiment to determine if the changes are physical or chemical. 

We made a glue and water mixture first. Then we made a water and Borax mixture. Finally, we poured the Borax into the glue mixture....and voila! 












Don't you just love everyone's faces? 




We determined that it was a CHEMICAL change since a NEW SUBSTANCE called POLYMER was created. 

How did that happen? When you add Borax, it binds the slippery glue molecules together in a web, so they can't move around as much. 


Borax turns the watery glue into a denser, more rubber-like substance called Polymer. 


The result? PURE FUN in science class!













It was unanimously decided that this was the BEST. SCIENCE. CLASS. EVER.
