The Rocks Project: Three visiting speakers.

Three experts visited. The first two guest speakers were geologists and the third expert showed the children how to make a rock garden in a transparent sphere.

The first guest speaker took the children outside where they dramatized a faultline of an earthquake. They also pretended to be the layers of the earth by arranging their bodies in various formations and movements. They ran 100 feet in order to compare their speed with the speed of the flow of lava from the Mt. St. Helens volcano. Upon returning to the classroom, our expert demonstrated various experiments to determine rock properties, described the three types of rock, and helped them make a collage to represent a sample of granite. 

Our second expert is a geologist, and the grandfather of one of the children. He donated core samples of rocks from Missouri where he works in mining, and told the children how rock samples are used in his work.

Our third expert helped the children construct a beautiful rock garden / terrarium in a transparent sphere, complete with a pond, some of the children's rocks, and assorted plants.
