Eggsperiment!

Objective: 1. Conduct the first half of the eggsperiment. 2. Complete the notebook quiz.

What's the eggsperiment? Students used large chicken eggs which had the shell removed using vinegar, revealing a cell membrane. The eggs are then placed in various "secret" solutions of water, sucrose, table sugar and/or corn syrup. The eggs sit over the weekend and on Monday students will be able to see if osmosis and/or diffusion has occurred.

Homework: none.
