After getting a better understanding about the water cycle we did a cotton ball experiment found at first-school. I gave "A" a cotton ball and said since we are talking about the watercycle what do he think the cottonball would be in the story? At first he said Drippy the raindrop. I redirected and asked if the cottonball looked like a raindrop. Once he said no he then figured out it was a cloud. I asked him to tell me what it felt like:"soft, squishy, light". Then he gently put it over a small bowl of water (our ocean). It was important he didn't submerge it. The cotton slowly would fill with water. Putting the cottonball down was to represent evaportation and as it filled with water condensation. Once the cottonball was filled I asked him to describe it again:"wet,cold and heavier". When the ball started to drip I asked him what that would be in the water cycle. He correctly said rain. I asked him why he thought it would drip water? I was hoping he would say that the cottonball was too full of water but it took him a while to get there. After we watched the precipation I asked where the drops were going? Since they were going back into our bowl (ocean) the water was doing the next stage-collection.
