Agenda 12/6—Day 5  Get out your lab books  Obtain a potato tuber  Put the tubers in order of how you think osmosis occurred based on the concentrations

Procedure  Get a paper towel  Label the with the 6 colors of the solutions  As you remove the potato, place it under the appropriate color  Handle the potato. What does it feel like?  Can you use your knowledge to explain what is happening in each potato?

Solutions  Distilled water=Blue .2 M Sucrose=Green .4 M Sucrose=Red .6 M Sucrose=Yellow .8 M Sucrose=Orange  1.0 M Sucrose=Clear
