Gummy Bear Lab
What do you think will happen to a gummy bear when you put it in water over night? Research Hypothesis: The gummy bear will dissolve in the water due to the fact that most gummy bears are made out of pure sugar. Also that since gummy bears are sugar and sugar usually dissolves in water. Also it will vary due to the amount of water that is used in the experiment. Null Hypothesis: The amount of sugar in the gummy bears and the amount of water that is used will have no effect on what happens to the gummy bears. Independent Variable(s): Foam Cup
Dependent Variable(s): Color of the gummy bear Controlled Variable(s): Amount of water Amount of time Control Group: There was no control group Materials and Methods Materials 1 Foam cup 1 Gummy Bear 50 ml of water Procedures First, measure the length of the Gummy Bear Second, measure the widest point of the Gummy Bear to get the width Third, measure the thickness of the Gummy Bear Fourth, calculate the volume of the Gummy Bear Fifth, measure the mass of the Gummy Bear using a triple beam balance Sixth, calculate the density of the Gummy Bear.

Conclusion Analysis My hypothesis was incorrect, because instead of dissolving in the water the Gummy Bear absorbed the water. This occurred due to the fact that some of the ingredients to make a Gummy Bear include a gelatin based ingredient. So due to it being made of that gelatin ingredient the Gummy Bear absorbed water like Jell-O instead of dissolving in it. Sources of Error The expected results of the lab were that the Gummy bear dissolves in the water getting smaller, not larger.
These were not observed due to the Gummy Bear absorbing the water instead of dissolving in it. Differences were due to my reasoning of what would happen to the Gummy Bear. Conclusion Statement I do not support my research hypothesis because the Gummy Bear did not dissolve in the water. I therefore agree with my Null hypothesis which states the amount of sugar and water will have no effect on the Gummy Bear, which is half true. We still do not know if there will be a different result when using less or more water.
