Our class has been exploring Earth Materials: Rocks & Minerals. We have been investigating a selection of the most common rocks and minerals that make up Earth’s crust, and have learned some techniques used by geologists to identify them.
Geology requires analysis. To develop analytical skills and techniques, we first took apart a simulated rock called a Mock Rock. We observed them, broke them apart, dissolved them in water, and evaporated the liquid to discover the ingredients from which our rocks are made.
We then moved on to real rocks and minerals, using scratch tools and acid (vinegar) to test for specific minerals.
Finally, we will look at granite, the base rock from which continents are made, and analyze it to discover the minerals it contains.
You can increase your child’s understanding and interest in earth materials by asking him or her to talk about the investigations we are doing at school. Rocks, which appear so commonplace, may become objects that inspire questions and promote close observation. You and your child may want to start a rock collection, or visit the library or (if possible) a rock and mineral display to expand your rock and mineral knowledge. A visit to a landscape materials center or a jewelry store (gems are minerals) can expose the broad range of uses for earth materials.
If you have questions or comments, or have expertise you would like to share with the class, please drop me a note.
