What Is an Egg Without its Shell?

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...

A chicken egg is a very large cell—perfect for investigating osmosis! Scholars conduct an experiment with vinegar and eggs that helps them understand the process of osmosis. They follow the activity with an in-depth look at osmosis in...

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....

As an anticipatory set, biologists listen to the story of Ruth Patrick, a scientist who used algae to detect water quality. They observe a demonstration of osmosis and diffusion. In their lab groups, they place Elodea stalks in...

Make walking on egg shells fun. You can walk across a carton of eggs without breaking any eggs by using the helpful tips provided. Your class can discuss how the shape and structure of the egg is able to withstand pressure if it is...

Students investigate osmosis using egg cells with the shells removed. In this osmosis lesson plan, students remove the shell of an egg by letting it soak in vinegar for two days. They take measurements and observe the cell. They soak the...

Students participate in a review of diffusion and the basic properties of the cell membrane before exploring the process of osmosis in a lab activity. Using shell-less eggs that have soaked in various solutions, students make...

Think bungee jumping looks scary? Knowing the science behind bungee jumping might make it less so. Using an egg and rubber bands, young engineers model bungee jumping. They test the distances that the egg falls for different numbers of...

Pupils 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 the...
