1. Label this one: Diffusion
Fill a graduated cylinder with water to the 100mL line.
Using the dropper place 1 drop of dye on the surface of the water.
Write your observations.
Observations:
2. Write this in your notes: Diffusion is when the particles move from an area of high concentration to an area of low concentration . For example, when you put food coloring drops in water, they move from very concentrated to an area of low concentration eventually reaching homeostasis or dynamic equilibrium.
Pour your water out and rinse the cylinder for the next group.

2. Label this one: Concentrations
Copy table and write your observations for both cylinders.
When your mom makes Kool-Aid she uses ½ cup of sugar. When you make Kook-Aid you use 2 cups of sugar. Compare the difference in concentration.
Cylinder A
Cylinder B
Low/High (Circle 1) concentration

3. Label this one: Selective Permeability
1. Write this statement: Selectively permeable means only some molecules can pass through the tiny spaces in a cell membrane.
Pour beaker contents into the sifter above the green tray. Shake the sifter into the green tray.
2. Write your observations
3. Explain how the sifter is like the selectively permeable membrane.
Pour green tray and sifter contents back into beaker for the next group!!!!

4. Label this one: Cell Membrane Structure
Using the color key and color pencils draw and label the structure of the cell membrane
Color key
Proteins
Water molecules
Lipid Bilayer
Lipid Bilayer
Pore/Channel

5. Label this one: Plasma/Cell Membrane Transport
Click on Plasma Membrane to answer the following: All substances that enter or exit the cell through
A. through the __________ _________
B. through the ___________ embedded in the membrane
C. processes of _____________ or ____________
Click on Oxygen and Carbon Dioxide Oxygen and Carbon Dioxide are similar because both_____....
Click on Glucose and Sodium Glucose and sodium are similar because both____...
Click on Potassium and describe what happened.
Click on Enzyme and note what happened.

6. Label this one: Active vs. Passive Transport
Watch this you tube video.
Her explanations are legit!
Copy down what she says and does.
It’s okay to pause the video just don’t take too long!
Set it back to the beginning for the next group.

7. Label this one: EggSperiment Explained!
Write this: Osmosis is the passive transport of water.
Watch the video to get a preview on what you’ll be doing on Monday!
Using what you learned from the video, describe why the egg can get bigger AND why the egg can get smaller.

8. Label this one: Membrane Structure & Function
Watch the video
What does she compare the cell membrane with? The cell membrane is like ______...
What are the parts of the cell membrane? The cell membrane is made of _____...
What do they say about osmosis and active transport? Osmosis is ________...and active transport is _______.

9. Label this one: Osmosis!
Make a table like this:
View the cool teacher sing his
awesome, visual song!
While viewing the video, make notes about isotonic, hypertonic and hypotonic. It’s okay to pause the video but paraphrase (shorten) to make notes quick!
Hypertonic
Isotonic
Hypotonic
Leave 2-3 lines for your notes
