This a before and after of the first gummy bear. We placed it into a blue food coloring and water solution. After 45 minutes we checked the results. Using a sharp knife, the soaked gummy bear was cut open and the class was surprised to see that the food coloring solution had diffused throughout the entire piece of candy that quickly. We had assumed that osmosis would happen at a slower rate.
Once we saw how quickly the color had diffused throughout the first gummy bear, we decided to soak a second one for a shorter time and see what happened. These are the results! Sorry they are a little blurry but you can still see the color change. This was after 8 minutes in the food dye/water solution.
The students then requested that the gummy bears both be placed back in the solution to soak over the three day weekend. There are many questions waiting to be answered. Would the gummy bears disappear completely? Would the color of them change even more? Will the gummy bear grow as much as the ones that were submerged in plain water? Only time will tell! :)
