October 13th - In Class and Homework

We continued our diffusion / osmosis lab today. We observed the iodine / starch and sugar interaction in the big beaker after 24 hours and discussed why it behaved the way it did. We set up the materials for parts 1B and 1C using the dialysis bags and the different molar sucrose solutions; and we used 4 potato cores. The homework is to think through what should happen in each case, as well as review chapter 6 and/or chapter 7 (Test next week - Wed or Thur)
