Earth Science Salt Crystal Formation Lab

In this 3rd through 10th-grade lab, students will observe the formation of salt crystals. Students will also add food coloring to their dissolved salt solution to demonstrate how chemical impurities can change a mineral's color. If you have enough students doing the lab your class will get to see many different results. This Earth Science lab comes with the student work, student image sample results, and with my own insights and explanations as to how the experiment can work well.
