polymers

Years ago, I put on a pair of snowshoes during a winter cold snap and found that the plastic binder straps broke fairly easily. At first I thought the plastic straps had simply become more brittle with time, but I found that the straps became less brittle when brought inside to warmer temperatures.

I just finished my first week of school, like many teachers in the Midwest. I work hard to get my Honors Chemistry students in a lab setting as soon as possible. It is difficult to find a perfect lab to do on the first or second day of school.
