Opener The diagram below shows a section of the lipid bilayer. Draw it. Label the hydrophilic/polar portions, and the hydrophobic/non-polar portions. Why does this structure make sense, given that the cell membrane exists in a water environment? hydrophilic hydrophobic

Agenda Final Presentations Modeling Transport across the cell membrane Osmosis and Diffusion Pre-lab Homework Juniors- I need to see your notes on Cell Membrane Transport Online Activity

Presentation Listen, Give Respect, Ask Questions at the end!

Modeling Cell Transport Work with a partner AT YOUR TABLE Roles: Doer and Explainer. Each partner will play BOTH roles. What to do: Cut out the molecules/ions on the sheet (FAST) Tape your cell membrane model sheets together (see example) Use the molecules/ions to model the cell transport described in each scenario Each scenario: pick a role, model transport, then switch roles Use the animated tutorial from last class (Section 10) You have 30 minutes

Osmosis and Diffusion Complete the packet about osmosis and diffusion to help prepare you for the lab next week. Use the reading for the lab as additional support to answer the questions.

Homework Read the background information for the lab next week (at the end of the packet) Answer the pre-lab questions Read Part. You should know how to set up and carry out the experiment when you walk in on Monday!
