Geology Rocks!

Last Thursday approximately 50 homeschooled students participated in Missouri River Regional Library's monthly homeschooling program. This month's theme was "Geology Rocks!"

Homemade fossils.
Students rotated through four stations.
Station #1: Sedimentary rocks and fossils. Here students layered different materials into a see-through container to see how the different layers of sedimentary rocks might come together. They also examined several pictures of fossils found in Missouri and made a "fossil" by pressing a shell into clay.

Station #2: Metamorphic and igneous rocks. Here students learned that igneous rocks are formed when molten magma cools and were able to observe a mock volcano and discuss how that lava turns into rocks. Then they learned that metamorphic rocks are formed by heat and pressure. They demonstrated this by making their own edible metamorphic "rocks" from Starburst candies.

Station #3: Rocks in everyday life. Here students discussed assorted items, guessing whether they were rocks or minerals. They then discussed rocks and minerals used in art and architecture, such as the Great Pyramids, the Sphinx, and Mt. Rushmore. Finally, students made their own art using minerals--chalk drawings.

Station #4: What's that rock? Here our resident geologist had several assorted rocks available for the students to examine and to ask questions about. Students were also able to question him about the rocks they had brought from home.

Please join us next month for a program on emergency preparedness. It will be held at the MRRL Art Gallery on Thursday, May 3, from 3 to 5 p.m. No reservations are required. It is designed for ages 6 and up, but younger students are invited as well. We hope to see you there!
