Launch Biotechnology into Your Classroom: Drug Delivery and Diffusion

Students examine why diffusion and osmosis happen in an egg cell.  In this diffusion lesson students demonstrate a semi permeable membrane.

[Free Registration/Login may be required to access all resource tools.] Tutorial defines osmosis and the difference between osmosis and diffusion. Students will learn how to distinguish solute from solvent and solution and the hypotonic,...

Students discover advances in biomedical technology such as transdermal delivery and other non-invasive procedures. In lab activities, they examine how medication is given and how molecules travel, observe electrophoresis, and conduct...

Young scholars distinguish between active and passive transport. Students identify key words associated with active and passive transport. They draw and explain the structure f the cellular membrane. They are able to define...

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...

Students learn about how medicines work in the body, and find out some information about dosing and packaging. The challenge is for student teams must produce a number of boxes to be used as packaging for a new medicine. Then they must...

Teach your class how to get out of a cell — or break in. The third installment in a seven-part series introduces the class to cell membranes and their functions. The lesson plan includes information to present to the class,...

High schoolers investigate osmotic balance in living cells. In this osmotic balance lesson plan, students use elodea leaves to study the effects of salt solutions on the cell. They compare the changes in an elodea leaf with salt water on...

Seventh graders examine different categories of plant life and their roles as producers of food and oxygen for other organisms. They study the evolution of plants from simple organisms to very complex ones. They look at the different...
