Osmosis
Fifth graders explore osmosis as they watch organisms divide. In this organism instructional activity, 5th graders use potatoes to experiment with the effects of salty water in the body. Students discuss what osmosis is and record what...
Curated OER
Cells
Middle schoolers explore the cell and cell processes. They create "cytoplasm", make a model of the cell and its organelles, and simulate the osmosis and the diffusion of materials into and out of the cell.
Curated OER
Cell Transport & Reproduction
Students are able to define the following terms: Osmosis, Isotonic Solution, Hypotonic Solution, Hypertonic Solution and Passive Transport. They read and complete a Mitosis worksheet, and play a Cell COmputer Game.
