Comparing Crystals

In this chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own. They will grow and compare three types of crystals and explore how a crystal forms as water evaporates from a solution. Though this activity was created as a pre-visit for a traveling science show, it makes a great stand-alone activity as well!
