Investigating Osmosis in Chickens' Eggs
You might not be able to learn through osmosis, but you sure can observe it! Scholars observe and measure osmosis using chicken eggs. They control for multiple variables to determine which variables have an impact and how the impact...

Cell Diffusion and Permeability: The See-Thru Egg Lab
Create a model to study a microscopic phenomenon. The seventh of 12 lessons uses an egg (without its shell) to represent a cell membrane. Using different solutions, learners explore the concept of cell diffusion. They monitor...
American Chemical Society
The Fate of Calcium Carbonate
Soften up an egg. Learners use vinegar to test for calcium carbonate in an egg shell and an antacid tablet and compare the reaction with vinegar to the reaction with water. In a second experiment, class members break down an egg shell...
Curated OER
Rubber Egg
Students demonstrate the semi-permeability of a cell membrane. In this rubber egg activity, students measure and record egg data, place the egg in jar with vinegar and close the lid, observe immediately and periodically for the next 3...

An Egg-cellent Osmosis Experiment
Students investigate the problem of osmosis by conducting an experiment. They use eggs with the shells dissolved to tell whether fluid can move across the membranes. The experiment provides high interest for all kinds of students to keep...

How do Hypotonic, Hypertonic, and Isotonic Solutions Affect the Water Movement of a Cell?
After removing the shell from a raw egg, cell biologists soak the egg in either a hypotonic, hypertonic, or isotonic corn syrup solution. They calculate the percent change in mass and compare it to the strength of the solution in a...

Observing Osmosis in a Chicken Egg
Tenth graders develop a hypothesis and explain what they observed on an activity. In this investigative lesson plan students observe osmosis and report their data using a graph.
Curated OER
Osmosis
Learners explore diffusion and active transport. They observe the effects of eggs in vinegar and predict what will happen when eggs are placed in corn syrup with food coloring. Students complete worksheets which lead them to describe...
Curated OER
What Causes Tooth Decay
Students investigate oral hygiene. In this personal health lesson plan, students discover the parts of a tooth and how to best protect them from disease. Students examine the effects of acids on tooth enamel and calcium.
