1. Rock crystal transformation

2. Procedure
We decided as a group that we wanted to see if we could make a rock grow crystals as we had seen it on YouTube.
We decided the three liquids we were going to experiment with were:
Water
Vinegar
Salt Water

3. Duration of Experiment- 5 days
On day 1 we placed three similar rocks into the liquid. After twelve hours there was no change.

4. Duration of Experiment- 5 days
On day 2 the water and the salt water had begun to turn a darker color and the vinegar had not changed color at all. No crystals had formed yet.

5. Duration of Experiment- 5 days
On day 3 there the water in both the water solution and the salt water solution had gone entirely black. The solution with the vinegar had begun to turn black but the consistency of the solution was much thicker than that of the water and the salt water solution

6. Duration of Experiment- 5 days
By day 4 tiny crystals had began to form on the rock sitting in the vinegar. They were tiny crystals but we’d hope by day 5 that there would be more. The crystals began to form on the sides of the rock.

7. Duration of Experiment- 5 days
By day 5 the rock immersed in the vinegar solution had not only formed small crystals but bigger crystals on the top. As a group we found this very exciting as the experiment had worked. The water and salt water solution had done nothing but dirtied the water.

8. THE END RESULT

9. OUR CONCLUSIONS
The vinegar solution worked over the water based solution and the salt water based solution because as the vinegar evaporates, aragonite crystals begin to form.
We researched and were told if it was left longer in the solution the higher volume of crystals would appear

10. Overall Thoughts
In conclusion, we thoroughly enjoyed this experiment and it was exciting to watch the progress of the crystals. 
