For the past week students have been learning about osmosis and diffusion through an egg experiment. Once the shell is removed, a raw egg serves as an excellent model of an animal cell. Students were able observe solutions of varying water concentration diffusing through the egg's membrane.
To conclude the laboratory experience, students will be spending the next week writing a lab report. Students may choose to present their data in the following formats: PowerPoint, Microsoft Word, Key Notes, 3-sided display board, or Pod Casting. The project will be completed entirely in class and should require no outside resources. To view the project components, click on the link below.
