The water cycle

This week we have been learning all about the watercycle. 

We made watercycles in a bag! We learned that during the water cycle no water is produced so we were careful to seal our bags up very tight so that no water could escape. We mixed blue food dye into the water. When the water evaporates in our bags the blue food dye is left behind and only the water evaporates. We talked about how this is similar to when the salt in salt water is left behind when the water evaporates. 

We have noticed that there is more condensation in our bags when we come into school in the morning than later in the day. We have figured out why this is. Can you?? 

During our art lesson on Friday we made models of the water cycle in shoeboxes. It was more difficult than we thought it would be!! We had to use some lateral thinking to figure out how to attach the pipe cleaners. The straws and cotton wool weren't easy either!
