Research:
I found out my information by looking at what the ingredients are in every liquid, including water, I also tried and searched, for the ingredients in club soda and vinegar. People have done a similar experiment to this, but they were testing different skittle colors instead. Also, research really helped me find the ingredients for the different liquids, like vinegar and club soda.

Hypothesis:
I think that the vinegar will dissolve the color of the skittle the quickest. The

So, why would water dissolve the skittles color the quickest?

Experiment:
In my experiment, I used three identical cups. The reason I used identical cups is because I didn’t want to create a new variable. My constant is that I didn’t change the amount of liquid in each cup. The way I did my experiment was I used 3 of the exact same cups, and the only difference was I used different colored cups, because I knew different colors would not change any of my data. The reason I used quantitative data was to find out how long it took for each of the different liquids to dissolve the skittles color. In my experiment, I had my stopwatch and 3 different cups. One contained water, one with vinegar, and one
