Cell Transport
Cell transport is movement of materials across cell membranes. Cell transport includes passive and active transport. Passive transport does not require energy whereas active transport requires energy to proceed. Passive transport proceeds through diffusion, facilitated diffusion and osmosis.

Cell Membrane Bubble Lab
In this lab, you will simulate the cell membrane by using bubbles. You will do all the procedures that are asked in the lab and sketch them, then on Schoology you will answer questions pertaining to the lab. I have also added a video of the lab, for those students who did not get to do this lab or if you just need a reminder when answering the questions. I will also have the video on Schoology so that you can watch it there too.

Lab Assignment
In Schoology, you will be typing up all the concept summaries and observations including concept 7 which is written below. Explain what you observed and how it is tied to the cell membrane. Then You will be looking up the fluid mosaics model and explain how this lab is connected to the fluid mosaic model and the function of the cell membrane.
Concept 7
1.Lift bubble frame out of solution so that a thin film spans across frame.
2. Hold the frame parallel to the tray.
3. Gently place the rubber band on the frame.
4. Rock frame back and forth to see the rubber band float on top of the frame.
5. Membrane proteins can also drift across the lipid bilayer.
6. Pop a hole on the rubber band and drop a paper clip through.
7. Notice how the rubber band creates a channel for stuff to go through. Proteins allow things to go through such as large molecules like glucose or even water through proteins called aquaporins.
