I;m looking for the Gummy Bear Lab,   I see it below, but can't open anything....   is there directions for this,   (mostly just how to make the solutions, I;ve got the gist of the rest).  Kaelen

the solutions are all made up to 50 mL each, containing increasing amounts of very saturated NaCl solution:

beaker 1:  0ml salt solution, 50 mL deionized water  (0% salt)

beaker 2: 10ml salt solution, 40 ml water (20% salt)

beaker 3: 20ml salt solution, 30 ml water (40% salt)

beaker 4: 30 ml salt solution, 20 ml water (60% salt)

beaker 5: 40 ml salt solution, 10 ml water (80% salt)

beaker 6: 50 ml salt solution, no water added (100% salt)

 

Each gummy bear must be individually weighed for each of the beakers before and after it sits over night.  Students then calculate and graph % change in each bear.
