Abstract:

The purpose of this experiment was to figure out which color dye in Skittles diffused fastest in distilled water. The hypothesis was that the lighter color Skittle would take less time for the dye to fully diffuse. The constants were the type of Skittle, the brand of water, and the glasses. The control was the orange Skittle. The independent variable was the color of the Skittle and the dependent variable was the time it took for the dyes to fully diffuse. The dependent variable was measured with a timer. The results of the experiment was that the yellow Skittle did not take the shortest time to diffuse and the red Skittle took the longest. My hypothesis was rejected because the different types of dye may change the diffusion rate. In the future I would do more replicants.

Title of Project—Test the Rainbow: The Effect of Time in Distilled Water on Skittle Diffusion Rate

Question or problem being addressed—How long does it take for the Skittle’s dyes to diffuse in water?

Goals/Expected Outcomes/Hypothesis—My hypothesis was that if the color Skittle was lighter, it would take less time to diffuse in water. 

Materials and Procedures—measuring cup, 2 clear glasses of the same size, distilled water, a timer, a recording sheet, pen and pencil, dry towel, original Skittles candy

1. Gather necessary materials.

2. Fill each glass with 177.4 mL of distilled water.

3. Place 2 of the same color Skittle on a dry towel.

4. Put 1 Skittle in each glass at the same time and start the timer.

5. Observe the Skittles until the dyes are fully diffused.

6. Stop the timer.

7. Record results.

8. Rinse and dry glasses. 

9. Repeat procedure for each color Skittle—red, orange, yellow, green, purple.

Data Analysis—Find the mean of the result for each color Skittle

Risk Analysis—There were no risks.
