rocks and minerals
By Wendy

Here are a few activities that I liked.
1. minerals are the ingredients of rocks. Make up a batch of cookies with choc chips, peanut butter chips, nuts, candies, etc. Pick apart with a toothpick or paperclip. What are
the mineral (ingredients) or their rocks (cookies)?
2. Mix glue and play sand. Form into cookie shapes and let dry. These are mock sandstones.
3. Go to a gardening center where they sell decorative stones. I bought a big boxfull of differnt rocks (granite, slate, etc) for about 5 dollars.
4. Light a candle and let some of the wax melt. Let the liquid wax drip onto a piece of foil

and harden. This is how igneous rock is formed. It is molten magma that hardens as it cools.
5. Have students do a birthstone report or craft
6. Drop vinegar onto chalk. The bubbling tells you that calcite is present.
7. Students can decorate a pet rock and write journal entries about its adventures
