Geologists at Work

We have started our first science unit, Pebbles, Sand, and Silt.  So far, we have been using 3 types of rocks. Our first experiment was finding out what happens when rocks rub together. (It makes sand!)

Our next experiment was finding out what happens when rocks are placed in water. 

The rocks changed colors and turned shiny. One kind even bubbled! The First Graders came up with even more rock experiments they would like to try. You may want to search for rocks around your yard or neighborhood and experiment at home.
