Most groups found that the vinegar, lemons, and food coloring made the gummy bears gain the most mass. Diffusion is the net movement of particles from an area of higher concentration to an area of lower, concentration. As you can see, the gummy bear in water will increase in size. The bear should be completely covered – cup about half full. Since the gummy bear does not contain water (remember, the water was removed when the gummy bear was made), water now moves into the bear by the process of osmosis.

Place the tap water bear on the wax paper and weigh it. To ensure the best experience, please update your browser. When diffusion occurs, molecules move from a higher concentration of water towards a lower concentration of water. Shake solution until the salt is dissolved, If you’re not completing this lab on your own you STILL need to read.

Introducing Textbook Solutions. - 19325955 Get step-by-step explanations, verified by experts. (Teacher will write this question on the board.) Osmosis occurred that molecules went through the membrane of the bear from the higher density to the lower density trying to become equal. Cover one with distilled water. Concentration. its about osmosis and on the 1st day the mass was 2 grams, second day 8 grams, now i need to find out the third day PLEASEE !! I created this as alternative to the classic "egg lab" for my special education middle school science class to observe a tangible model of osmosis.
