Disappearing Puddles

In P1, we have started a new topic - Water.  We will be looking at how water changes state, using everyday examples.  Today we were observing the sun heating up and taking the water out of our puddles to make the clouds in the sky.  We made lots of little puddles and drew round them with chalk so we would know where they had been.  When we came back after half an hour they were gone!  We decided to make a really big puddle to see if the same thing would happen.  It did!
