Welcome Back!!
Wednesday/Thursday 10/14-10/15/2015
Agenda: 3G Activity Quarter 1 Review
Activity: Microscope Review and Lab
Homework: No Homework Tonight

2. Give, Get & Given 3G Review Activity
Write down any term (in the “Given” column) that you do NOT already have.
Scientific Method
Independent Variable
Dependent Variable
Biochemistry
Eukaryotic cell
Prokaryotic Cell
Nucleus
Organelles
Claim
Macromolecule
Homeostasis
Cell theory

3. Give, Get & Given 3G Activity
2. You will pick 1 word from EACH of the 3G columns.
3. You may NOT have the same words as anyone else at your table.
4. On the back of your 3G sheet, write the words, its definition and explain how each of the terms are interconnected.
5. Explain in pictures how the terms are connected. The drawing must be creative and colorful.
6. 3G Review Activity is worth 15 points 

4. Microscope Lab!!
Today we will be looking at the letter “e” and your very own cheek cells while practicing how to use a microscope
First, we need to review the components and important features of microscopes
activity/en/
After we have mastered how to use a microscope, we will be looking at different species of plants and their cells! *

5. Microscope Lab!! Cheek Cell Directions!!
Wet Mounting for Slides *

6. Friday 10/16/2015 Agenda: Notes on Diffusion
Activity: Cellular Membrane Activity
Homework: No Homework Tonight
Strand 4: Life Science Concept 1: The Cell PO3: Explain the importance of water to cells. PO4: Analyze mechanisms of transport of materials (e.g., water, ions, macromolecules) into and out of cells: -Passive transport -Active transport

7. When talking about cells, explain what a “membrane” is.
A cell membrane is a barrier around the cell that allows things to come in and out of the cell
Ask students to explain what a membrane is… *

8. Functions of Membranes
Protects cell
Separates the cell from the environment
Maintain ion concentrations of various substances
Selectively permeable - allows some molecules in, others are kept out
*Explain what each of these functions are *

9. Selectively Permeable: Examples
In your notes, explain in your own words what it means to be selectively permeable.
What are 3 examples of selectively permeable barriers in your everyday life?
Share your examples 
Students will write some everyday examples of things that are selectively permeable; ask students to share their examples *

10. Phospholipid Bilayer
The cell membrane is made of a phospholipid bilayer.
Phospho = phosphate (an element)
Lipid = FAT
Bi = TWO
Layer = stacked *

11. Question Do lipids like to be in water? How do you know?
HINT: Do oil and water mix?
Lipids (FATS) do NOT like water
Lipids have a PHOBIA of water  *

12. Explain the Hydrophobic tails: Hydro = WATER, Phobic = FEAR, Hydrophobic tails do NOT touch the water of the cell *

13. Explain the pictures of the phospholipid bilayer*

14. Parts of the Phospholipid Bilayer
Hydrophilic = loves water
THINK!! A person who is a “bibliophile” LOVES books!!
Hydrophobic = hates water
THINK!! A person who is “arachnophobic” HATES spiders!!
Walk around room to make sure students understand how to draw & label phos. bilyer *

15. Other Stuff in the Cell Membrane!
The cell membrane has a lot of stuff in it besides phospholipids. Some other stuff in the cell membrane are PROTEIN CHANNELS, RECEPTOR MOLECULES, AND CHOLESTEROL.

16. Cell Membrane Foldable
Draw and label picture of the cell membrane
Make sure to add color and label all parts of the cell membrane (Top Inside Flap of foldable)
List the functions of the cell membrane
Use the vocabulary you learned from today’s notes (Bottom Inside Flap)
Related Terms for Cell Membrane
What are other terms used to describe the cell membrane? (Bottom Inside Flap)
Walk around room to make sure students understand how to draw & label phos. bilyer *
