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.
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.
It€™s time to start mixing things up! In this pretend STEM scenario, you are a chemist for a bath and body products company and it€™s your job to make and test different cosmetic products. Use the tools in your laboratory to employ different scientific techniques and essential chemistry principles to make soaps and bath bombs. Try out different additives to affect the color, smell, and other qualities of the products you make.
Real science and pretend play come together in this activity-filled kit that can be used alone or as an extension of the Ooze Labs Chemistry Station (a Parents€™ Choice Silver Honor winner!). As you mold different glycerin soap shapes, you learn about the chemical properties of soap that help it pick up and wash away dirt. While you€™re concocting bath bombs, you learn about how acids and bases combine to form fizzing reactions, and what a pH level is. Expand your cosmetics knowledge with an overview of the biology of skin care and other science related to soap and bath products. All materials and chemicals are non-toxic.
