In Biology 30 we have been studying how cells can maintain a stable internal environment. This lead to an investigation of passive and active transport. To illustrate osmosis we created a Gummy Bear Osmosis lab where we essentially placed gummy bears into different solutions to see whether or not osmosis would occur. In doing so, we discovered that Vinegar, 7-Up, Tap Water, and the Baking Soda solution were hypotonic and caused the bear to swell. In some cases, quite extensively going from 2 grams to 9 grams! The rubbing alcohol was hypertonic and the pancake syrup was isotonic. Check out some of our lab results below.
