Curated OER
Potato Lab
In this osmosis worksheet, students put a strip of potato in three different solutions and document the changes in the potato to determine is the solutions were hypotonic, hypertonic, or isotonic. This worksheet has 6 short answer...
Curated OER
Keeping a Balance
In this cell fluid balance worksheet, students read about how fluids are transported in and out of a cell through the cellular membrane. Students compare cells that are isotonic, hypertonic, and hypotonic. This worksheet has 3 matching...
Curated OER
Osmosis
In this biology worksheet, students determine how many solvent and solute molecules there are in the red blood cell and the IV fluid. Then they determine whether the IV fluid is hypertonic, hypotonic, or isotonic to the red blood cell.
