How in the world is a musk oxen like a phospholipid? Learners see the fluid mosaic model and all of its complex parts: phospholipids, proteins, glycoproteins, glycolipids, and cholesterol. The video then focuses on the phospholipid's and protein's role in keeping material in and out of the cell and to maintain its fluidity.

Instructional Ideas

• Give learners a fluid mosaic model drawing on which they can take notes
• After the video, have learners explain the analogy between cell membranes and musk oxen

Classroom Considerations

• Must have a computer, Internet access, and a projection system
• Part 33 in a series of 37

Pros

• Relates musk oxen to a phospholipid
• Provides a complex drawing of cell membrane, but the focus is on phospholipids and proteins so as not to overwhelm learners

Cons

• None
