Shared writing with the class, typed by Mr. McGaughey

We learned alot about rocks and minerals at Wye Marsh. We learned that
limestone can hold fossils and buffer the water. We learned about
erosion by building structures made of soil, gravel and wood chips. Then
we poured water on them to see if they collapsed. We were junior
geologists when we collected rocks and sorted them into three piles. We
played games which showed why rocks and minerals are important to the
environment.

It was fun!
