SKITTLES LAB

Experiment on dissolving

1) Question/Problem Will water, hydrogen peroxide, or sprite dissolve the Skittle first?

2. Hypothesis – If Skittles are placed in three different solvents, then I predict that the Skittle placed in Sprite will dissolve the fastest because it is carbonated.

3. ExperimentA)Materials: Hydrogen peroxide water

Sprite cups spoons Skittles

B)Procedures

1) Place Skittle in three cups (one in each)2) Pour 2 teaspoons of water in one cup

3) Pour 2 teaspoons of hydrogen peroxide in one cup4) Pour 2 teaspoons of sprite in one cup 5) Check every 2 min. and note size6) In ten minutes check to see which skittle is the smallest
