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...

Osmosis
Fifth graders explore osmosis as they watch organisms divide. In this organism lesson plan, 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...
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...

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
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...

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....

Osmosis Demonstration Lab
Even though they were written for upper-level high schoolers or college pupils, the labs herein are possible to use even in middle school. In the activity, kids observe osmosis in both potatoes and elodea plants, then record and graph...
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
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...
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.

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.
