Third grade mineralogists created crystals in two different ways. Crystals are a special kind of solid material where the molecules fit together in a repeating pattern.
In our first investigation, we dissolved Epsom salt in hot water and created a solution.We poured the solution into Petri dishes. As the water evaporated, the crystals were left.
In our next investigation, I poured 1/2 cup each of bluing, distilled water, and ammonia on top of damp sponges. After the three liquids were added, I placed food coloring and 1/2 cup of salt on top of the sponges.
