Tension... The fun kind!

Today we are studying surface tension all day and our first experiment is to see how many drops of water fit on top of a penny. This is also our introduction to estimating. We talked about reasonable guesses and looked at what two drops of water looked like before we guessed. I think they made pretty good guesses, we are doing the follow up experiment after recess. We are also learning about bugs that walk on water, and doing a rather e plosives experiment after lunch. It is going to be a blast!
