The 3rd grade has completed their seed walks and seed dispersal lab. They tested several different seeds to determine how far they might travel, and which ones were best designed for wind dispersal. Students also looked at seeds that hitchhike, are carried by an animal, float in the water, and might pop out. Another thing students noticed on the seed walk was a special, odd-looking growth on the stems of the goldenrod. At first they thought it was a seed, but then found out it was a gall, which is the home to the gall wasp larvae. They were pretty amazed when they saw the larvae coming out of the egg inside the gall.

The JK completed their fall walks using their powers of observation as we walked through the woods and open fields. Students saw and heard geese, gulls, crows, a woodpecker, and a very special bird, the Eastern Bluebird. We watched as the parent bluebirds were getting the family ready to migrate. The JK students also noticed the galls on the plants and couldn't believe that an insect could live inside of it.
