Curated OER
Diffusion and Osmosis Challenge
Challenge your biology class to analyze an experimental setup, in which a selectively permeable membrane separates two distinct solutions. They consider the concentration of the contents and answer ten questions pertaining to the...
Curated OER
Cell Size and Shape; Diffusion and Osmosis Processes
Use salmon eggs as a cell model for demonstrating the movement of water over concentration gradients. Junior scientists examine the same process microscopically with an onion cell. They use a thistle tube and a semipermeable membrane to...
Curated OER
Investigating Osmosis
A thorough investigation of cell transport is provided when completing the assignment. The first half requires biology class members to answer questions about diffusion and osmosis with the aid of diagrams. Then they fashion an...

Investigating the Effect of Concentration of Blackcurrant Squash on Osmosis in Chipped Potatoes
Model and explore osmosis using squash and potatoes. Young scientists expose chunks of potatoes to different concentrations of a squash solution. They compare the weights of the chunks before and after exposure to the solution and use...
Curated OER
Osmosis
Students investigate osmosis and diffusion in a liquid environment. In this osmosis lesson plan, students use dialysis tubing made into bags and filled with 3 different solutions. They observe the movement of water molecules into higher...
Curated OER
Diffusion across a Selectively Permeable Membrane
Lab groups fill a section of dialysis tubing with glucose and starch solutions and suspend it in a water bath. They use iodine as a starch indicator and a glucose test strip to find out if either of the materials crossed the selectively...
Curated OER
Semipermeable Membranes and Bioaccumulation
Beginning biologists place a drop of food coloring into water of differing temperatures to observe the effect on the diffusion rate. They remove the shells from raw eggs and then experiment with osmosis over the remaining membranes....
Curated OER
Diffusion & Osmosis with Data Analysis
Students explore principles governing diffusion and osmosis. Students perform a dialysis tubing experiment. They obtain core samples of potato in varying concentrations of sugar-water to measure water potential of the potato cells....
Curated OER
Dispersement of Particles: Diffusion and Osmosis
Students explore the dispersement of particles. In this science lesson plan, students describe the many ways in which particles move and transfer from one source to other areas.

Love in the Time of Cholera
Young scholars examine causes and treatment options for cholera. In this biology lesson, students model the osmotic basis of cholera using dialysis tubes. Young scholars propose treatments for hypothetical patient.
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...

Structure and Function of Cell Membranes
Lead your high school class on an exploration inside the cell. Individuals investigate the relationships between cells structure and function given their relative locations on the cell membrane. They explore the concept of homeostasis...
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.

Plasmolysis in Elodea Plant Cells
Students 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.
Curated OER
Cell Size Changes
Learners examine the behavior of living cells treated with different types of stimuli. They watch an online movie, examine wet mount slides under a microscope, take an online quiz, and analyze data.
