Growing Salt Crystals is a Fun Geology Experiment for Kids (and adults, too)!

Hey Mini Me Geologists! Try this fun experiment to learn more about growing salt crystals. Did you know that the salt you put on your food is actually a mineral? Salt forms naturally by precipitation or evaporation. In this experiment, you will watch salt crystals form by precipitation because it is just more fun than watching water dry and leave salt behind, although you can try that method, too. Grab an adult to help you with the stove and boiling water but the rest you can do on your own. In nature, salt will precipitate from mineral-rich water in oceans or lakes so you will simulate ocean water to grow your crystals.
