This term we had a chrysalis of a Monarch Butterfly in our classroom. We had it for four weeks. It was in a little box and we had to mist it with water until the chrysalis turned dark. Then we waited.
We got so much better at observing the changes we could see in the chrysalis. After four weeks our chrysalis opened up and we had a tiny butterfly. Its wings were curled and it climbed up the side of the box. Soon its wings got a little longer and we could let it go.
