Tuesday, April 26th

1. Homework is to read all about the Endocrine System (hormones!) in your review book.  Focus particularly on glucose regulation and calcium regulation.

Today we took Vocab Quiz 5

I then began our lesson on Cellular Respiration.  You can review this information in your review book and in Chapter 9 of your text.  Can you tell I am late to pick up my son from daycare???  See you tomorrow!

Monday April 25th

1. Vocabulary Quiz 5 tomorrow!
2. Homework: Worksheet for Cell Respiration due on Block Day
3. Final Exam will be 5/2 and 5/3.  That is next Monday and Tuesday!

In 2nd and 3rd I started with a check of the weekend reading assignment on 10.4.  By afternoon word had gotten out, so I did not give the checkup to 5th and 6th. 

We went over C4 and CAM plants and emphasized how they have adapted their Carbon dioxide fixation for their hot, dry climates.  Information can be found in 10.4.  We then looked at last year's Photosynthesis Quiz to check our understanding of photosynthesis. 

I ended class by giving out a worksheet that asks questions about the main points of cellular respiration from Chapter 9.  This worksheet is due on the block day.

April 22nd: Eight class days before AP Bio Test!!

1. Homework is to read about adaptations for alternative carbon fixation on pp. 195-198.
2. Our Final Exam will take place in class on May 2nd and 3rd.  If you have a conflict with an AP test we will come up with a solution together. 
3. Review sessions are continuing!  There are still five more.  Sessions are held from 3:05 to 4:35 on the dates below.
     Today the topic is Classification and Diversity. 
     Tuesday 4/26 - Plants
     Friday 4/29 - Animal Systems
     Tuesday 5/3 - Ecology
     Thursday 5/5 - open forum

In class we went over the online photosynthesis lab that was assigned Tuesday.  We discussed the role of DPIP and why we expect to see certain trends in certain situations.  I then collected the assignment.  Next we finished our discussion of photosynthesis by focusing on the Calvin Cycle.  The key components to remember are: The 1-carbon CO2 is joined to a 5-carbon RuBP molecule by Rubisco (yay Rubisco!).  This unstable 6-carbon molecule immediately splits into 2 3-carbon molecules.  ATP and NADPH from the light dependent reactions are then used to create carbohydrate while regenerating RuBP to start the cycle again.  The cycle would need to run 6 times (using 6 CO2 molecules) to create 1 glucose.  Here is a link to an animation on the Calvin Cycle.  http://www.science.smith.edu/departments/Biology/Bio231/calvin.html

On Monday we will go over the alternate pathways for carbon fixation and begin cellular respiration.
