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.
Set of 10 additional student charts and mineral samples for use with the What Mineral Is It? classroom project (Item # 12044).
The study of rocks is an essential part of studying the age and evolution of Earth. In Rocks, students will examine the characteristics of each of the major types of rocks: igneous, sedimentary and metamorphic. From stalactites and stalagmites to intrusive and extrusive rocks, students will examine how rocks are formed in this exciting program. A visit to Mammoth Mountain in California showcases the interesting rock formation known as the Obsidian Dome, while a fun, hands-on demonstration illustrates how different sized-particles of sediment settle out of water at different rates. Part of the Earth Science in Action DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.
Minerals are an important part of everything around us -- from the pencils we write with to the airplanes in the sky. Even the earth beneath our feet is packed solid with these essential building blocks. In All About Rocks and Minerals, children will discover the characteristics of minerals and see how different minerals make up different kinds of rocks: igneous, sedimentary and metamorphic. A visit to a lapidary shop examines some beautiful gemstones, while a fun, hands-on investigation demonstrates how solid crystals can be made from a liquid. Part of the Earth Science for Children DVD Series. A teacher's guide is available online. 23 minutes. Grades K to 4.
Grow a marvelous crystal garden with these fast-growing crystals. The centers of four flower cards bloom into delicate crystal structures in just a few hours. You can practically see the crystals form before your eyes on the branches of filter-paper trees. Learn about how and why crystals form, and experiment with different colored flowers.
