Objectives: Compare and contrast passive and active transport. Predict the movement of molecules (including water) across a semipermeable membrane.
1. Students create a 3D pyramid from handout.
2. Students watch a 7:48 video on cell membranes and cell transport.
3. Students draw and label a phospholipid layer with channel proteins on the back of their worksheet.
4. Students analyze diagrams on active and passive transport, explain their reasoning, and predict the movement of water molecules through a cell membrane.
Answer key is shown in the preview file. This file prints fine in black and white.
Note: The video selected is short, and the Amoeba Sister videos, are well received in my classroom. Two others of different groups lengths are, Membranes and Transport, https://www.youtube.com/watch?v=dPKvHrD1eS4 (11:45), or Cell Membrane, Passive Transport (4:40), https://www.youtube.com/watch?v=JShwXBWGMyY .
Add a "Do Now" and "Ticket Out the Door" and you have a complete lesson.
