Evaporation...

This week in science, we examined "evaporation".  Students were given the challenge of making five drops of water evaporate (any way they could).  In our first trial, the times were all over the place... from about one minute thirty seconds to over four minutes.  But... someone figured out that RUBBING the water on the desk made it go away fast.  So in our second trial, we decided to tighten our "variables" (a concept discussed the week before), and have everyone rub the water drop.  In this trial, everyone was done in less than thirty seconds!  The challenge was a great way to not only reinforce the science experiment concepts discussed previously, but also deconstruct one component to the water cycle and see it in action... in our classroom.
