36" x 24" full color laminated poster.
This is an outstanding rock identification chart! The introduction explains that each type of rock is the result of a specific mixture of minerals subjected to a clearly defined geological process. It shows and describes the most common rock-forming minerals and variations that occur within rock types.
The bulk of the poster is divided into three sections, one for each rock type: igneous, sedimentary, and metamorphic. An illustration shows how they are made, and a photograph shows a natural formation. A dozen other photographs show representative specimens. Each is accompanied by an informative caption citing identifying characteristics and common variations.
A bonus section shows and explains some of the more specialized and popular rock forms, such as geodes, concretions, agates, and meteorites.
This is a great poster for earth science classes. Rock collectors find it invaluable for quick reference.

Crystals are fascinating creations of natural beauty. Diamonds, gemstones, rose quartz, snowflakes, sugar grains, and table salt are all crystals. Grow your own crystals and explore these exquisitely ordered structures in a fun, creative way with six crafty experiments. This kit includes five different chemicals and other tools for growing crystals. Grow a crystal cloud inside a rainbow. Watch pink iridescent crystals form from a translucent solution. Grow long needle-shaped crystals. Mold plaster hearts and flowers and then grow a layer of pink crystals on them. Create the perfect solution to get crystals to form on a granite rock. A specially designed experiment station provides molds and growing basins for your crystal creations. After you have grown your crystals, store them safely in three clear, locking display boxes. Learn how and why crystals form, and tips and tricks for getting the biggest, most beautiful crystals. Full-color, 16-page experiment manual.
