Gummy Bear Experiment

For our diffusion experiment our group decided to work with salt water and gummy bears. Our experiment tested the weight of the gummy bears per salt dilutions. Our tests included 1g 2.5g 5g, 1.5g, and 10g of salt diluted with water. We knew that the higher the concentration of salt diluted into the water the heavier the diffused gummy bear would be, therefore we measure weight as our numerical data.
My hypothesis was that the 10g dilution of salt would have the gummy bear with the largest mass. This was because diffusion is the process where the molecules of both substances interact, with a constant kinetic energy. Therefore because the salt would increase the mass of the water, it would in result also increase the mass of the gummy bear because of the kinetic energy that interacts with both sets of molecules.
In our planning stages we attempted to find a project idea which would vividly …show more content…
However when our experiment was finished and we fished our gummy bear out of the salt solution, to our surprise there was no correlation between our results. (As shown in the graphs on the next page). There are many reasons for why our results have no correlation (0g and 5g have the highest weights) ,the first would be while we were attempting to extract the gummy gears from their salt water solution many of them broke apart and we had to coffee filter them out which may have cause lots of variation and discrepancy in our data. Second during our process the gummy bears may have diluted into the water as well (this is common problem found during diffusion related experiments). Finally we may have gotten the results we did because of the fact we used table salt for some of our tests and rock salt for the rest ,this was because what was readily available to us a the moment in time and we did not believe it would cause such
