=**BELL RINGER (10/1)**=
 * ===Have hw out on desk===
 * ===Be in seats ready for directions.===

=ACTIVITIES: Directions are below. There is a template at the bottom of the page if you would like to open it to type your answers into that document. You will need to use the links on the wiki because they will not open from the Word doc.=


 * STATION 1:** Lab Practical – Mrs. Murray


 * STATION 2:** Lab Practical – Miss Sipple

· Divide section 7-3 among your group of 4. Have each person read a section and jot down some notes in their journal or type up notes in the computer. (**5 minutes**) · For the last **10 minutes** at this station you will teach each other about the section you read about. **HINTS:** If you type up your notes in Google Docs you can share them with your group members. **I would divide the sections like so:** 1. What is the cell membrane mainly composed of? 2. What are 5 types of molecules in the cell membrane? 3. What characteristic should a molecule have in order to pass easily through the membrane? 4. Fibrous proteins serve what purpose? 5. Channel proteins allow what type of molecule to pass through? What molecule does the tutorial show as an example passing through? 6. What is the purpose of globular proteins? 7. True or False: Cholesterol is only found in animal membranes. 8. Summarize four functions of proteins in the cell membrane
 * STATION 3:** Jigsaw
 * 1. Diffusion Through Cell Boundaries (blue heading) pg 183-184 **
 * 2. Osmosis (blue heading) pg 185-186 **
 * 3. Facilitated Diffusion (blue heading) pg 187 **
 * 4. Active Transport (blue heading) pg 188-189 **
 * STATION 4**: **[|Construction of Cell Membrane]**
 * · Go thru the interactive at [] then complete the following questions: **

1. Does passive transport require energy? 2. What are the three types of passive transport that you looked at? 3. In which direction do molecules move through the process of diffusion (with respect to concentration of molecules)? 4. What is the difference between diffusion and facilitated diffusion? 5. What is the difference between diffusion and osmosis? 6. If the inside of the cell membrane is hypotonic and the outside is hypertonic, water will travel across the cell membrane until //what// is reached? 7. What is the difference between active and passive transport? 8. Describe what is happening in the ion pump animation. 9. Where does sucrose get the energy it needs to pass through the membrane? 10. “Cell eating” is also called __and “cell drinking” is also called__ _. These are both examples of _.
 * STATION 5**: **[|Active and Passive Transport]**
 * · Watch the “Passive Transport” videos first then watch the “Active Transport” then answer the following questions: **

· Read through the information then click on “Animal Cell Membrane Tutorial” – work through all the problems until you get them correct. (Take notes in your journal) · When finished click on “Plant Cell Tutorial” and do the same thing (answer all questions correctly and write answers in your journal).
 * STATION 6**: [|Osmosis and Diffusion]

If you finish all stations go to [|http://nhscience.lonestar.edu/biol/bio1int.htm#transport] and explore the different links under “Cellular Transport”
