Solutions to the problem:
 * make the video informative
 * research what dialysis is
 * keep the video exciting
 * research dialysis treatments

12/3/10 Today we did a lab about osmosis. We weighed the tubes we made that contained distilled water and sucrose (15% and 30%).

12/6/10 For the osmosis lab we made four dialysis tubes that we filled with 15% sucrose (1), 30% sucrose (1), and distilled water (2). After filling the tubes we weighed each tube and recorded results, then put each tube in a seperate beaker either filled with distilled water or 30% sucrose. We also weighed them and wrote down results after 10 minutes and then again after school. We observed that when we weighed the tubes the weight would increase, not change, or decrease. We concluded that having the tubes liquid match the liquid in the beaker makes the weight increase the most but pairing 30% sucrose tube with distilled water in the beaker makes the weight decrease over time.
