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!

The publishers of the Science, Naturally books contacted me and introduced me to some great science resource for kids. I'll be receiving a copy of the book One Minute Mysteries: 65 Short Mysteries You Solve With Science! soon & will post my review here.
On their website, they post a Mystery of the Month that will really get your kids thinking! Your students read about a mystery & then must use their scientific knowledge to solve it! Love this idea!
