Normal Elodea Leaf
Plasmolyzed Elodea Leaf (Salt Water)
The ENZYME LAB was discussed and is due tomorrow. Data:

Now, for the rest of the unit, the topic will be cancer. We took a survey online and filled out a chart in our UP on page 55. The survey can be found here . There is a cancer research paper due on 10/25. The chart will be needed for the paper. The rubric was handed out in class, ask Mrs. Stein for a copy if needed.
