New Question: "How does the IV affect the DV of the (cells to be tested)?
| Independent Variable (IV) | Dependent Variable (DV) | cell type or device used to test osmosis |
|---|---|---|
sucrose (table sugar) concentration |
% change in mass | dialysis tubing |
salt (NaCl) concentration |
% change in length | chicken egg |
temperature (Remember your info about enzymes to know how hot you can get membranes before denaturation occurs!) |
% change in volume | potato cells, melon cells, etc |
Veggie piece size (diameter) |
rate of % change of mass (or of length or volume) | |
| Time |
You can choose variables from different columns and rows to make a unique question.
Examples:
1) How does the concentration of sucrose affect the volume of chicken eggs?
2) How does temperature affect the change in length of melon cells?
3) How does time affect the % change in mass of potato cells?
etc...........
