class 10-28

I thought today was another great day of presentations. Once again, each group did a great job of sharing their specific activity and safety tips. I really like the experiment with the elephant toothpaste, as I believe younger students would as well. I was unaware that the mixture of those items would cause it to foam. I thought that all the groups did a wonderful job of pointing out any safety tips that would be of concern when doing the experiments with students.
