For those of you wanting to wrap up the stickleback activity: 
 
Monday, February 26: Clean up Day.  Go over the big tests so far and correct mistakes.  Go over the rubrics for the FRQ's to clarify misunderstandings.  Wrap up Eukaryotic Gene Regulation with team. 
There will be a little time in class on Monday for teams to finish up their PitxI gene models.
 Tuesday, February 27th:  Bacterial Transformation; Introduction to pGlo Lab
Wednesday-Thursday; February 28th, March 1- pGlo Lab
Friday, March 2- pGlo Lab data analysis
 
 
 
 
Hope your President's Day was restful!
 
Tuesday, February 20th: PCR Activity. Record in lab journal. At home you should finish up the Gel Electrophoresis Analysis.  The questions are on here--> in the right column.
 
Wednesday,Thursday, February 21-22:  Gene Regulation Activity
Friday:  TEST.  FINALLY!! Chapters 16,17,20.  (We'll drop back and get 18-19 next week.)
 
 
 
February 16:  Your Friday GIFT!!-  We need to finish the lab; therefore, the test on Chapters 16,17 will be moved to Wednesday.  Keep reading ahead.  We're already doing labs in the DNA Technology chapters, obviously, so we'll be ready for a test on those chapters (20,21) very soon.  These labs constitute a bulk of the test material, so it will benefit you to pay attention to the labs as we go!
 
If you like those videos where you get to see and hear the real people who discovered DNA, here's the link to my DNA lessons webpage.  We may not get to watch all of them, but I love the historical perspective of hearing them talk about the challenges.
 
Here's the link to Wed/Thursday lab, February 7-8.  If you're out sick, we have all the templates in class.  If you're just wanting to get ahead (crickets chirping...), this is the link to the directions and summary questions.  We will have some time in class Friday.
 
Link to a codon chart:
 
Monday, February 12- Finishing up basics of DNA. 
Tuesday, February 13- Restriction ENZYMES and introduction to biotechnology
Wednesday/Thursday February 14-15:  Lab:Gel electrophoresis and DNA analysis  
Friday February 16: Test: Chapters 16 (DNA) and 17 (Central Dogma,woof)
By Popular Demand:  In answering the summary questions, 1-5 can be based on your shortened polypeptide.  6-11: you do NOT have to copy the entire transcript.  Use "...ACT..." to represent a changed nucleotide within its codon.
 
Monday, February 5 - Finish genetics (the questions you saved til the day before the test that should have been done days ago) and start DNA- history and structure.
Monday's presentation:   http://www.dnai.org/lesson/go/9262/
Pay close attention to the Griffith lab and the Hershey-Chase labs.  Be able to state claim, evidence, and reasoning for their observations.

Monday, January 29 - Mendelian Genetics Review, Chromosomal Inheritance
"ASSIGNMENT:  Genetics problems, pages 283-285, 1-22; pp 303-304, 1-17.  READ "Tips for Genetics Problems" on p 283 before launching in. "
 
 That assignment is in quotations, because it has been on the website for about a week now.  Monday we'll talk about the ones causing you angst, but don't forget the answers are in the back, Appendix A.  I won't be upset if you don't understand.  I'll be upset if you haven't tried them.   
  
January 30th-31st.  Fruit Fly Simulation.  Make sure you've logged into the web site and made an account.  You create the user name and password.  Use the appropriate class code listed below.

 Feel free to sign on and play with the flies before next week's lab.
 
Thursday, February 1st- Early dismissal.  If I see you, we'll talk about the practice problems that are confusing you.
I have a great 4-point FRQ that would fit perfectly in a shortened period. It links genetics and meiosis. That's a hint.
 
Friday, February 2nd- Finish Genetics and review

TEST ON MONDAY FEBRUARY 5th, Mitosis, Meiosis, Genetics I & II.
 
I watch you turn in your lab books and get on your phone, even as I remind you that you have a standing assignment.  At some point, your frontal lobe has to override the dopamine dumps in your midbrain from text messages, and you need to make the connection between work ethic and success.  My nagging loses its impact.  
 
 
 
ASSIGNMENT:  Genetics problems, pages 283-285, 1-22; pp 303-304, 1-17.  READ "Tips for Genetics Problems" on p 283 before launching in.
 
 
 Bozeman Biology Chi Square
 
 
 
FROM WEEKS PAST -
 
  Most of you had finished sketching mitosis phases and calculating life cycle by counting the 200 cells, and you're ready to analyze meiosis/crossing over in Sordaria.  Here are some web sites that will let you do that from home.
 
Here's a really good explanation:
 
 
 
 
 
Here's a copy of the lab protocol:
 
 
pp 13-17
 
You can Google "Images, Sordaria crossing over" and find a number of images that you could use to count ascospore crossing over, then calculate percentages and map units.
 
AND, here's our buddy Paul Anderson, to help clarify:
 
This lab is the first grade of the second semester, and it can be completed at home.  I encourage you brave souls who actually looked at this web page to do the analysis.  You can transfer it to your lab journal after Middle Tennessee thaws.  Stay safe and warm !!   We'll be moving to Mendelian genetics on returning to school so the test will include genetics and cell division.  Remember, that should all be a biology I review (That's my way of trying to get you to panic less.)
 
 
 
 
 
Well, I just wrote a big explanation of the new semester, only to not have it publish.  So we'll talk in class.
 
Monday: Chromatids vs Chromosomes, Cell Cycles and Super Chromosomes
Tuesday: Mitosis vs Meiosis- Review of Biology I
Wed/Thursday: Cell Division Lab
Friday: Quiz on Cell Division 
 
If you're reading the textbook, this is Chapters 12 and 13.  It should be a review of Biology I Concepts.  The handouts in class will be the bulk of information from which tests will be taken.  In an effort to truly cut down on homework, we're shifting away from reading the text and focusing on reviewing what we did in class.  Remember when I asked you to study a LITTLE every night?  Your brain needs to review what we discuss in class. 
 
To cut down on retakes and test corrections, both of which have you looking backwards as we're trying to move forwards, with each new unit, I'll have copies of old AP Biology Tests available for you to review.  I won't have enough for everybody to take, but you can take pictures of any/all of them.  My hope is that your exposure to that level of questioning will raise your level of preparation.
 
I'll still be available every day during lunch/study hall, somewhere on the science wing- usually in the computer labs.  As they're becoming more booked, I'll possibly be in Mr. Burns Room.
 
 "She Didn't Teach.  We Had to Learn it Ourselves."  Good article from a collegiate journal.  You are not alone in your feelings.

Monday, December 11: Quiz on Cellular Respiration/Photosynthesis
Tuesday December 12: Cell Communication, Cell Signaling, Endocrine System
Wed/Thursday, December 13-14: Cell Communication Lab
Friday, December 15: Wrap up Endocrine/Cell Communication/Cell Signaling.
 
This week we will wrap the two toughest concepts of Biology: Cellular Respiration and Photosynthesis.
The test will be Monday, December 11.  We'll spend the last week before exams finishing up Big Idea II, Energy.
 
 
 
 
 
 
On Tuesday, November 21, you'll share the results of your photosynthesis inquiry with a mini-poster.
The boards are laminated with headings, but you'll be sharing your data- tables and graphs- and your discussion of how your variable impacted photosynthesis.
 
 
 
How to calculate Standard Deviation on a TI-84:  Save yourself grief and watch this!
 
Tuesday, November 21:
Dark reactions of photosynthesis and alternatives to C3 metabolism
 
 
 Maybe if I quit telling you the plan, the plan will quit changing...
 
Monday, November 13: Introduction to Photosynthesis
  HOMEWORK:  Watch these two videos:
This is the protocol you'll follow for the leaf disk lab Tuesday and Wednesday from Paul Anderson, Bozeman Biology guru.
 
My colleague, Brad Williamson, who invented this lab, helps you trouble shoot the process of sinking leaf disks.
 
Here's one version of the protocol for this lab.  You'll have the lab manuals for step by step instructions, but you'll have to introduce YOUR variable.
 
 
Tuesday and Wednesday, November 14 & 15, Leaf Disk Photosynthesis Lab Assay
COME TO CLASS HAVING WATCHED THE VIDEOS ABOVE.  Have in mind a variable that you would like to test.  Some variables might include color of the light, light intensity (how close it is to the samples), concentration of CO2 in the infused solution, other sources of CO2 besides baking soda.

If you're going to need something not commonly found in the lab, not included in the list above, and can justify its selection with solid science, let me know ASAP.  
 
Thursday, November 16: TEST ON ENZYMES, Chapter 8
Friday, November 17: Photosynthesis, Dark Reactions and Alternatives to C3 Metabolism
 
 
 
 
Lab Write-Up Protocol!?  The link below is packed with great tips. 
Include sketches under methods and materials!!  EVERY DATA TABLE NEEDS A GRAPH!!
 
 
EXAMPLES of strong lab reports.  "Viewer discretion is required"- understand that the format of their labs may differ from yours, and your write ups could therefore differ.
 
Here's the enzyme powerpoint covered before lab on Wednesday and Thursday.  Make sure you're competent on all these aspects of enzyme structure/function.
