Instructions:
Don't feel pressured to do this in one day (unless you are starting this on Friday).
Use the videos to help you answer the questions to the right.
The video will pause at each designated time.
The video section before the pause will have answered the question that opens up.
If you did not hear the answer or the question does not make sense, pull the cursor of the video back to the start of that section and listen to it again.
Tip - It might be helpful to watch the video all the way through, without trying to answer the questions, replay them, and then answer them. It's your choice, whatever works best for you.

Learning Goals:
Explain the main roles and components of the cell membrane including phospholipid bilayer, cholesterol, carbohydrates, and proteins using the fluid mosaic model. (IN.9-10.4.1)
Compare and contrast passive transport mechanisms like diffusion and osmosis and explain how they allow for the movement of molecules and ions across membranes. (IN.9-10.4.2)
Investigate factors that influence the diffusion rate, such as distance, temperature, concentration gradient, characteristics of the substance diffusing, and surface area to volume ratio. (IN.9-10.2.1)
Analyze examples of osmosis in plant and animal cells and explain how osmosis contributes to functions like turgor pressure, transportation of water and minerals, and homeostasis. (IN.9-10.4.2)
Design and carry out an experiment to determine the effects of environmental factors like the solute concentration on living organisms using concepts like hypotonic, hypertonic, isotonic, diffusion, and osmosis. (IN.9-10.1.1, IN.9-10.1.2, IN.9-10.1.4)
