Being able to label all the parts of the chloroplast and mitochondria (and what is going in/coming out at each step), then use those to answer questions is also key.
What is the difference between ATP and ADP?
What does oxygen production tell you? What if something is producing carbon dioxide?
Why is the sun so important?
What is fermentation? Why does it occur? When does it occur?
What is glycolysis? Why does it occur? When does it occur?
How much ATP is made in each stage of glycolysis -> cellular respiration?
What is a producer?
If you can answer these questions well, I think you will be very successful tomorrow.

Fun with an Egg and Osmosis
Osmosis is a very important process for moving WATER through membranes in and out of cells. We are going to take an egg and immerse it in Acetic acid for a day. The acid will remove the shell, providing a natural cell membrane around a giant cell with which to experiment. We will observe when water moves inside and outside of the egg, which is determined by the concentrations of water in and out of the cell. Read the ENTIRE LAB, and then write 2 hypotheses.
Write EVERYTHING in your lab book. This should include: Prelab, Lab Materials, Methods (procedure), Data (Data Table & Observations), Interpretation, and Conclusion.
Hypothesis 1: After removal of the shell, what will be the direction of osmosis, into or out of an egg when placed in vinegar? The egg is 8% dissolved substances and 92% water. Vinegar is 5% solute and 95% water. Explain your reasoning.
Hypothesis 2: What will be the direction of osmosis, into or out of an egg when placed in corn syrup? The syrup is 60% solute and 40% water. Explain your reasoning.
LAB: Experimental Design
Clear plastic cup
1. Measure the mass, volume, and circumference of an egg. How you do it is up to you. Record observations in data table.
2. Set the egg in a plastic cup and pour vinegar over the egg until it is covered with about 3 cm of liquid. Cover the cup with saran wrap.
3. Observe any chemical reactions taking place and record these in the data table. Place the beaker and egg in your drawer for 24 hours.
1. Observe any changes to the egg and record.
2. Carefully remove the egg, rinse and dry it. Measure the mass, volume, and the circumference again. Record data and observations.
3. Pour on the vinegar and rinse the cup. Add 1 inch of corn syrup to your cup then add the egg. Cover and leave in your drawer for 24 hours.
4. Answer questions 1-3 in the interpretations.
1. Carefully remove the egg and measure the mass, volume, and circumference again. Record data.
2. Observe any changes to the egg and record the data and observations in the table. Be sure to fill in each box in the table. Label the units in parentheses.
Data Continued: Describe qualitative changes in the egg.
1. After the shell was removed when immersed in vinegar, in which direction did the water move, into or out of the cell?
2. Use tonicity terms to compare the egg and the vinegar when initially placed together.
3. Explain the direction of the water’s movement in terms of the concentration of water, both in the egg and in the vinegar.
4. After immersion in the syrup in which direction did the water move, into or out of the cell?
5. Use tonicity terms to compare the egg and the syrup when initially placed together.
6. Explain the direction of the water’s movement in terms of the concentration of water both in the egg and in the syrup.
7. For centuries, salt and strong sugar solutions like corn syrup have been used to preserve foods and protect them from being colonized by living bacteria and fungi. This was long before refrigeration was invented. Why do these solutions defend against spoilage so effectively? The egg was a model of all cells including bacterial and fungal cells, which spoil food. What would happen to bacteria and fungi which land on food treated by these substances?
Restate your hypotheses and tell if they were supported, contradicted, or not supported.

Today we attempted to take 3.3 Notes on the Cell Membrane
We'll finish the notes tomorrow - yes with a powerpoint, yes, there are IMAGES you need to understand. It doesn't make sense to learn this just using words. You can handle drawing these into your notes.
Homework for Tuesday:
Read the Egg Lab
One uncooked, unfertilized egg (one per lab pair)
Homework for Wednesday:
Rotifer lab (links below)

I have decided to push back the due date on the Cell Organelle Project to Monday, November 3rd. Before you throw a parade, understand the the upcoming due dates will look like this:
Monday, Oct. 27: Cell Diversity Lab Due (in lab book), Lab Quiz
Tuesday: Start Egg Lab
Wednesday, Oct 29: Rotifer Lab Questions Due
Thursday: Finish Egg Lab
Friday, Oct. 31: TYPED WASL write up of Egg Lab Due. This can be mostly complete before you take your final measurements on Thursday, and you will have had Thursday to work on the class computers.
Monday, Nov. 3: Cell Organelle Project Due
Tuesday Nov 4: Tentative Ch. 3 Test Date
Due: Wednesday October 29, 2008 by 2:30pm.
This project will be completed outside of class.
You will produce a travel brochure that describes a plant or animal cell as if it were a real destination. This could be an amusement park, ball park, zoo, farm, mall, etc., there are many possibilities!
You must accurately describe and diagram at least 10 organelles (attractions) from the list below. In your brochure, you must justify how you have represented their functions. The associated drawings or graphics must include the object the organelle represents as well as the drawing or graphic of the actual organelle. If you draw, you must draw neatly and your organelles must be neatly colored.
- Decide on a plant or animal cell – each has its own specialized parts.
- A good way to start would be to define and describe the function of each organelle/structure.
- Figure out how the parts work together.
- Decide on a business/vacation destination/factory/etc.
- Align organelles and structures with the parts of your destination.
I will not accept projects that are not submitted in a brochure-like format.
I will not accept projects that do not fit into an 8 ½ inch by 11 inch area.
- Central Vacuole
- Cell Wall
- Cell Membrane
- Endoplasmic Reticulum
- Golgi Aparatus
- Plasma Membrane
Humor and creativity are strongly encouraged.
Note: At moments your teacher can be "thought impaired". Make sure you have a good justification as to why you have represented your organelles in the manner you have in your brochure.
A SUCCESSFUL ORGANELLE PROJECT HAS THESE FEATURES:
- Organelles described in the brochure with accuracy, having both a real organelle picture and a real world representation picture.
- Brochure Design Neat, no scribbles, visible white-out, erasing, etc.
- Brochure uses at least 6 colors in design. Neat, with few visible corrections.
- High degree of creativity, humor, and originality
- Grammar & Spelling: Fewer than 2 errors
- Rubric Rubric Attached, 10 Organelles included
Total Points Awarded: / 70 possible points

This was the only classtime we will spend on this project before it is due. If anyone still has questions about hypothesis (and I recommend you read the book for assistance too!) or would like their procedure checked over, I can do that before or after school on Thursday.
HOWEVER: we're using the following:
MANIPULATED (not "independent")
RESPONDING (not "dependent")
CONSTANT VARIABLES (not "constant")
You may complete this in pairs BUT remember that if only one student from the pair is absent the assignment is still due!
Spot Be Gone includes:
- Experiment Title
- Variables identified: manipulated, responding, controlled (at least 2)
- Complete Materials List
- Clear Procedure, including validity measures and multiple tests for reliability
- Experimental Control
- Data Tables (should be left empty, do not make up data!)
Please contact me with any questions!
