This STEM science kit contains everything you need to grow three colorful crystal formations – emerald green, aquamarine blue, and golden citrine. Begin observing crystallization within just a few hours of completing the chemistry portion of your experiment. Then, watch crystals grow over several days. A full-color STEM poster teaches about the different types of crystals and their applications in technology like televisions, radios, and computers. Build and paint a model volcano. Simulate an eruption with baking powder and vinegar (not included). Lava glows in the dark! Ages 8+ Adult supervision is required. Smithsonian Crystal Growing Value Set
