Curated OER
Cell (Biology)
Students conduct a series of activities to explore the nature of cells. In this biology lesson, students observe plant and animal cells under the microscope and compare them. They differentiate osmosis and diffusion.
Curated OER
Molecules Rock
Fourth graders engage in this interactive lesson which illustrates diffusion and osmosis and shows them that molecules of life move dynamically and powerfully. They must analyze their lab orally and in writing.
Curated OER
Plasmolysis in Elodea Plant Cells
Young scholars microscopically observe various subcellular components. They determine the effects of different salt solutions on Elodea plant cells. They detect the presence of chloroplasts, cell walls, and cell membranes of Elodea.
