Liam (age 5), above, our naturalist, asked for many days if the silkworms were big enough to hold yet. 
Finally, the children got to hold the worms. It was an exciting day.
April is silkworm month at Windsor. As you've heard from your pre-kindergartners, we have live 
silkworms in the classroom. The children have been very critically observing  them. Many complex questions about the worms come up, some which we have  to look up together.
The children will observe the full silkworm life cycle, as it  unfolds before their eyes. We had about 50 eggs, about half of which  hatched within the past couple weeks. The children take turns feeding  the worms mulberry leaves twice a day, a task they take great pride and  joy in.
