My kids had a great time experimenting with 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. I would have expected the salt water gummy bear to shrink so we are going to repeat that experiment & add more salt this time. The vinegar (which is actually a dilute solution of acetic acid) almost completely dissolved the gelatin, those bears were really falling apart!
