Chemistry Experiments at Merriam Park Library by Ann Treacy

Today we went to the Merriam Park Library for some chemistry experiments. They stuck a skewer through a balloon to demonstrate the elasticity of polymers. The heated a wire into a new shape because it is created with an alloy that was formed at a very high temperature. In a cooler temperature the atoms become flexible but once heated the atoms again become rigid and sort of snap back into shape.

So now I feel like we could all pass a high school chemistry test – well maybe not quite, but I’m hoping that when some of us take high school chemistry that these experiments will come back to them and help them pass some test or get some scholarship.

It was a fun day.
