Osmosis and Dialysis
How do you engage pupils in a discussion about osmosis without leaving them overwhelmed? By providing them with the tools to perform an exciting experiment, and they will see osmosis in action! Young chemists and biologists use a potato...

Osmosis
Fifth graders explore osmosis as they watch organisms divide. In this organism lesson, 5th graders use potatoes to experiment with the effects of salty water in the body. Students discuss what osmosis is and record what happens in...

Osmosis in Potato Slices
You may find this presentation helpful in setting up the classic experiment where potato wedges are used for observing the effects of osmosis. You can view the experimental setup in the text and a lab sheet in the pictures, but you will...
Curated OER
Starch
Students examine the basics of starch and how it is used in food. In this photosynthesis lesson plan students experiment with variables that affect starch production in photosynthesis.
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....

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
Making Hypotheses
Fourth graders practice making hypotheses about what they believe occur as they perform an osmosis experiment in class. This experiment is designed to illustrate how important it is to make an accurate hypothesis.
Curated OER
Blood Tonic
Students investigate the process of osmosis using fresh potato cuttings in saline solution. In this biology lesson, students explain the difference between hypertonic, hypotonic, and isotonic solutions. They collect data from the...

Do Salt Water Fish Drink?
Students conduct an experiment with potato cores and a sucrose solution to investigate how salt water fish process water. They develop a lab report of their experiment.

AP Biology Lab Review
A seventy-two slide PowerPoint that reviews several lab explorations done in an AP Biology course. For each lab there is a description, concepts, and conclusions. Many pictures and graphics make this visually appealing, but it would not...
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.
