My hypothesis was not true. 7-Up did not produce the largest        Do sugar crystals grow
crystal formation on the bamboo skewer. Unsweetened apple juice     bigger in water,
formed the largest crystals with the greatest mass. I used an       unsweetened apple juice, or
electronic balance to take the mass (quantitative measurement)      7-Up?
and took notes as well throughout the experiment by observing
how the crystals were forming.

Results of the Three Trials
Unsweetened Apple Juice-3.636, 3.708, 3.652
7-Up- 3.354, 3.401, 3.321
Water- 3.091, 3.079, 3.087

Why did unsweetened apple juice produce the most crystals, I
believe? Unsweetened apple juice may have evaporated more in
response to nearby sunlight.
