Tonicity: Hypertonic, Isotonic, and Hypotonic Task Cards
These cards can be used as a reinforcement activity after the lesson, as a review prior to a test, or as game cards for any number of educational games.
If laminated, these cards will last for years. I cut my task cards with a paper cutter, hole punch one corner, and put on a ring for ease of use.

Task Card Content:
Students are asked to:
1. Identify the solute concentration of solutions in dialysis tubing, cells, and beakers that are pictured on the cards.
2. Determine if a solution is hypertonic, isotonic, or hypotonic when compared to another solution. These solutions are in beakers, cells, and/or dialysis tubing.
3. Determine the direction of net water flow based on the tonicity of the solutions.
4. Identify the definitions of hypertonic, isotonic, hypotonic, crenation, lysis, and turgor pressure.
5. Explain what will happen to the cell in a stalk of celery that has been placed into distilled water.
6. Explain how and why there is a change in the mass of dialysis tubing that has a different solute concentration than the beaker it has been placed in.
