Saturday was Kate's last chemistry class with Northwestern Univ. CTD. It unfortunately, was a much shorter session than the last one...unfortunate because she enjoyed chemistry so much more than brainbusters. On the last day, parents are invited in to see a small bit of what they've been working on. First up was the classic, vinegar/baking soda/food color experiment.
PS--don't you love all the girls in this class!?
