Central Park's Umpire Rock is a Manhattan schist, the very
bedrock that runs beneath nearly all of
Central Park. It is a tough exterior that
was formed some 450 million years ago
in the Paleozoic Era


The purpose of our trip to Central Park is to observe and describe metamorphic rocks . The Umpire Rock (above) is a Manhattan Schist, a type of metamorphic rock. This type of rock is found all over the park. You can contact the Urban Park Rangers, if you want a guide, but you can do it yourself. You can set out just about anywhere. I would ask the children to think about the rocks they saw yesterday and see if those rocks have any of the same characteristics as the rocks in Central Park. The children should have their Science Notebooks with their notes from Lesson 1. They should also have pencils. I would start at Umpire Rock. It is the large formation by the baseball fields. Any large formation will do. I would ask the children to look at the formation and compare it to the rocks they worked with in Lesson 1. I want to know if any of them recognized that they had Manhattan schist. [ Each group did have Manhattan schist].
