Evaporation

We are investigating evaporation as part of the  water cycle.  We went outside and the children poured water onto the concrete. They then drew around the puddle. We Came back at the end of the day and the water was gone. We found out that the heat from the sun made all the water evaporate back up to the clouds. An important part of the water cycle. Did you know the world has always had the same amount of water!
