On Friday of last week, we poured the liquid from our vials that sat over night into evaporation dishes to see if we could find any other ingredients in our mock rocks that are not visible to the eye. Through evaporation we were hoping to discover the other ingredients.
Monday, the children were so excited to find CRYSTALS!!!
Using a crystal identification sheet, the children were able to figure out what other ingredients were in our mock rocks.
Ingredients of our mock rocks: red and green gravel (pretend minerals), oyster shells (pretend minerals), alum, epsom salt, flour, and sand!
