My kids had a great time experimenting with gummy bears! We used the "Black Forest" brand of Gummy Bears - results may vary depending on the brand you use. Here is what happened with the Black Forest gummy bears:
Gummy bears do some interesting things when put into different liquids. We wanted to find out what would happen when we put gummy bears into water, salt water, vinegar, and baking soda water. We measured 50 mls of each liquid & added 1 tbsp. of salt or baking soda:
Here's what our overnight results look like:
We recorded length & mass before & after the experiment.
My students completed a lab report with 2 charts and 2 graphs for data analysis, here are 3 of the 6 pages:
All of the gummy bears GREW due to osmosis. Water left the gummy bear in the salt water solution, that is why those gummies grew the least- although they did grow a little. The gummies always grew the most in vinegar. The vinegar (which is actually a dilute solution of acetic acid) almost completely dissolved the gelatin, those bears were really falling apart!
