we did a group experiment on the starch level in water, the instruction of the report is in the picture file upload. we added 0.1 percent of starch in 10ml of water in a dialysis bag, we added a 0.3 percent of starch liquid in 10ml of water in another dialysis bag, and 0.5 percent of starch in 10ml of liquid in a dialysis bag, Every 12 minutes we take out the dialysis bag and weight the liquid, to see the weight of the liquid. The hypothesis is “the higher the concentration of starch, water movement across the membrane (the dialysis bag), will be slower”. i need a graph showing the weight of the bag according to the time.
