Active and Passive Transport: Red Rover Send Particles Over
I can move about freely, but you cannot. The class models the movement through cell membranes by way of passive and active transport. Members of the class play the roles of various proteins, atoms, compounds, and cell actions and mimic...
Curated OER
Mystical Membrane
Students investigate osmosis, diffusion and a semi-permeable membrane. In this cell membrane lesson plan, students observe the movement of molecules out of a bag filled with sugar and starch into a beaker of water. They test the beaker...
Curated OER
Diffusion
Learners describe and illustrate the process of diffusion in selelctively permeable cell membranes. They are asked to respond to what they think will happen when food coloring is dropped in a bowl of water. Other activities will be...
Curated OER
Diffusion through Membranes
Students identify diffusion and its processes through experimentation and calculations. They also use a CBL and conductivity probe to measure the conductivity of various solutions and study the effect of concentration gradients on the...

Cell 5 Diffusion and Osmosis
Students distinguish between active and passive transport. Students identify key words associated with active and passive transport. They draw and explain the structure f the cellular membrane. They are able to define phospholipid...
Curated OER
Cell (Biology)
Students conduct a series of activities to explore the nature of cells. In this biology activity, students observe plant and animal cells under the microscope and compare them. They differentiate osmosis and diffusion.
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
Diffusion Across a Selectively Permeable Membrane
Students investigate how water passes through cell membranes. In this biology lesson, students differentiate osmosis and diffusion. They illustrate the movement of water in both processes.
Curated OER
The Effects of Osmotic Balance and Imbalance In Living Cells
Students investigate osmotic balance in living cells. In this osmotic balance lesson plan, students use elodea leaves to study the effects of salt solutions on the cell. They compare the changes in an elodea leaf with salt water on it to...
