10/13/14 Journal Discussion Questions Using your textbook or smart phone, please answer the following: 1. Draw an animal cell in a hypertonic, hypotonic and isotonic solution. Using an arrow, show the direction of water flow.  

Hypotonic solution Isotonic solution Hypertonic Solution

Reminders Final Draft is past due!! Check the webpage if you are absent! If you are growing plants for Science Fair you need to start Start working on your Science Fair Laboratory Composition Notebook. Follow the instructions in your Science Fair packet carefully. It tells you exactly what to do and how to do it. Cell Root Word Quiz is TOMORROW 10-14-14 Cell Exam is on 10-16-14 (you should have read chapter 7)

Monday Naked Egg “Eggs-periment” Working in your same “Egg” groups you will complete the last part of the Egg Lab 1. Pour the corn syrup and molasses into the trash (NOT the sink) 2. Make qualitative observations (describe, draw and label) 3. Make quantitative observations Get the mass of your egg in grams (keep it in the cup; you already know the mass of your cup from Day 1). Record in your journal. 4. Put the cup and the egg in the trash. 5. Be ready to share your results with the class after the ppt notes and practice problems from Friday

Cell Membrane (and transport) Notes And Naked Egg “Eggsperiment” Finish the ppt & Practice Problems Discuss the lab

Post Lab “Eggs-periment” What did the egg represent in our experiment? What happened to the egg when we placed it in vinegar? What happened to the egg when placed in water? Corn syrup? Molasses? Why? Was the water a hypertonic, hypotonic or isotonic solution? How about the corn syrup? Molasses? How could this relate to real life and YOU? 6

“Cell-f-ies” 7

“Osmosis Practice Problems” Working with your shoulder partner, complete the practice problems. 8
