86 & 87 Diffusion and Transport handout
Get the Diffusion and transport handout, fasten to pp.86-87
Have a great day, and please make sure to plug the computers in!!!
If you have time, check out the mitochondia video (links or OUT folder), you can see great examples of facilitated diffusion and active transport.

85 Implications of Osmosis and Diffusion
Discuss with your group, and formulate an answer for the following based on our investigations into osmosis and diffusion:
1. Why do grocery stores spray their fresh produce with water?
2. If a shipwrecked crew drank salt water, they could die. Explain why...
3. If a bowl of fresh strawberries is sprinkled with sugar, a few minutes later they will be covered with juice. Explain why this happens.
4. If you place a carrot in a salt water solution, it will wilt. Why?
5. What kind of solution should you store vegetables in if you want them to be nice and crunchy? (Hypo-, Hyper-, or Iso- tonic) Why?

84 Isotonic Solutions
What is an isotonic solution?
What happens to a cell when placed in a isotonic solution?

83 Hypertonic Solutions
What is a hypertonic solution?
What happens to a cell when placed in a hypertonic solution?
Which of the solutions that you placed the egg in was/were hypertonic? What molecules do you think diffused across the membrane, and what is your evidence that something diffused across the membrane?
Draw a before and after picture for the hypertonic solution(s) showing what moved.

81 Diffusion and Osmosis
We've seen some interesting things happen in the lab lately, and we need some vocabulary to help us accurately describe what has been happening.
Please give definitions and a visual example (drawing) of:
1. Diffusion
2. Semi-permeable membrane
3. Osmosis
What is the difference between osmosis and diffusion?

80 Egg Lab Observation Summary
Summarize your observations during the egg lab, if you had a problem, or breakage, go ahead and just summarize what the class observed as a whole.
1. What happened when you placed the egg in the vinegar solution?
2. What happened when you placed the egg in the syrup?
3. What happened when you placed the egg in water?
Include any reliable quantitative observatations you made - if you made mistakes, describe what went wrong and how you could improve your technique.

79 Prokaryotes vs Eukaryotes
Title P.79 Prokaryotes vs Eukaryotes
Go to the slide show for p.77, and examine slides 86-90 (use the bottom right corner shortcut), then answer the 3 (or 4) questions below.
Watch the "Parts of a Cell" video from the Khan Academy LINK
 |
| From Cell Organelles |
- How do prokaryotic cells differ from eukaryotic cells? (answer in a paragraph)
- How are "proky" and "euky" cells similar? (answer in a paragraph)
- Categorize plant, animal, and bacterial cells as prokaryotic or eukaryotic.
- To go Above and Beyond, research and explain the endosymbiotic theory

78 Plant Cells versus Animal Cells
Project 78: Plant Cells versus Animal Cells
(watch this video)
1. List the three main structures that plant cells have that animal cells don't
2. Describe the function of each of these 3 plant cell structures
3. List at least 5 structures that are in both plant and animal cells (can you do more?)
Review time...
(check out the KHAN ACADEMY tutorial about PARTS OF A CELL)
For those of you who want to work ahead:

77 Cell Organelles Foldable part 2
Happy Turkey Week!
(a heads-up, progress reports go out on Wednesday...)
Monday startup:
A. Get a computer or two per group, log in, open the blog
B. Get your notebook, check your grade online (use the link, click on grade book)
C. If you think there's a mistake with your grade, tell me in person privately
D. If you want to improve your notebook scores before progress reports, mark your fixed pages with bookmarks, and hand them in on Tuesday.
Project 77: Cell Organelles Foldable part 2
1. Tape in the second foldable on p.77
2. Open the Cell Organelle Powerpoint in the OUT FOLDER (get someone to help you if you STILL don't know how to do this...)
3. Be patient, it'll take a while to load with everyone killing the network
4. Finish the foldable insides with the name of the pictured structure, and the function of the structure (WHAT IT IS, WHAT IT DOES)

The Egg part 4
A. Complete the day 4 activities, data, and recording for the Egg.
B. Dispose of the egg in the ziploc bag
C. The 2 graphs are homework
Keep working on Project 76 - scroll down to the blog entry for details
We all noticed that the eggs were a bit bigger after sitting in the water, some even burst. Hmmmm... we also had a nice little popping ceremony in ziploc bags, and "buried" our eggs in the special place...
Question to consider - why did the egg get bigger, then smaller, then bigger? What do you think is moving in/out of the egg?

The Egg part 3
Start with the usual:
A. Get a computer for your table (leave your ID, please remember to plug it in when you return it!)
B. Log in
C. Go to the blog
D. Turn your notebook to the correct page
E. Complete the tasks
THE EGG, part 3
1. Follow the instructions in the packet for day 3.
2. Record your observations in the data table - leave this out for discussion
3. Make sure to dispose of the syrup in the proper containers (NOT THE SINK!!!)

The Egg part 2
A. Write down this blog address in your table of contents "CHAPMANBIO.BLOGSPOT.COM"
B. Get a computer for your group and log in
C. Go to the class blog!
1. Observe your egg and record your observations (use the data table)
2. Measure how much vinegar is left, and dispose of it properly
3. Rinse and weigh your egg (don't let the egg touch the balance - figure it out!)
4. Now figure out how you are going to do the DAY 2 part of the EGG lab
5. When it's your group's turn, do the DAY 2 stuff for your egg investigation
6. Make sure to record ALL of your MEASUREMENTS, show any CALCULATIONS, and write down your observations...
A few things we noticed... soaking the eggs in 100ml of vinegar for two days didn't quite dissolve the entire shell so we had to wash it a bit. Replacing the vinegar after one day helped, or using a 400ml beaker and 200ml of vinegar worked pretty well :-)

76 Cell Organelles part 1
1. Use the handout to create a foldable for the first 8 Cell Organelles
2. Pictures are on the outside, inside has what it is, and what it does.
3. Use Cell Organelles to help you finish the foldable
4. Check out the video links (see below or use the LINK tab at the top of this page). If you're getting blocked on campus, look in my OUT folder (ALL PERIODS) for the videos, or just wait until you have internet access off campus.
Notes -->
