Water type does affect growth of crystals. Every crystal needs a seed, but ocean has so much that it reduces space for crystal growth. If there are strings placed in the solution (1st and 2nd experiments) distilled will grow the best because the string will serve as a string. If there are no strings placed in the solution (2nd and 3rd experiments) fresh water will grow the best because of the moderate amount of seeds it has.
This proves that with no extra materials added into the solutions, alum crystals will grow the best in fresh water. My hypothesis was proved wrong because ocean grew the worst and fresh grew the best.
This project tests Crystal grow influenced by fluids they are grown in.
