Subject area/course: Biology
Grade level/band: 11–12
Task Overview:
- This task demonstrates the importance of osmotic balance for cells to function properly, and what the consequences are when that balance is not met. This task fits into the curriculum of basic cell biology. After researching diffusion and osmosis, students will test their understanding by doing experiments to explore how solute concentration affects diffusion and how cells react when placed in different kinds of solutions. Students will develop hypotheses based on their understanding of diffusion and osmosis and will write a 4-page lab report, including an introduction, methods, results (including a graph), and discussion section.
