Respiration Quiz on Tues 2/14


  • Distinguish between ventilation, cell respiration, and gas exchange
  • Identify parts of the respiratory system on a diagram:  trachea, bronchi, bronchioles, alveoli, diaphragm, intercostal muscles
  • Outline structure and function of the alveoli.
  • Be able to state the shape and function of type I and type II pneumocytes
  • Be able to outline the process of breathing in terms of muscle action, pressure, and volume
  • Be able to explain why muscles come in antagonistic pairs and identify the antagonistic pairs in breathing
  • Be able to describe how you would go about doing a ventilation experiment
  • Be able to outline the causes and consequences of both lung cancer and emphysema

General Outline That Gets Us Through the IB Exam

This is the plan I have come up with after all the snow days.  You will note that we will be moving very fast!  But hopefully knowing what we are doing will help you plan things out.  If there is interest, we will also likely incorporate some review from last year into FLEX so that we can gradually go over the concepts from last year, instead of cramming it all in at the end.

Fri 2/10:  Check off DBQ's on p 312 and 318 and go over.  Review Respiration Topics for Quiz on Tuesday 2/14.  Start antibiotic lab and read about antibiotics in 6.3.
Tues 2/14:  Respiration Quiz.  Measure Zones of Inhibition on Bacteria Plates and start processing.
Thurs 2/16:  Full Draft of IA due through turnitin.com (with some flexibility).  Notes on barriers to infection, blood components, blood clotting, and antibody production.  Work on Antibiotic Lab, due Thurs 2/23 in pairs through turnitin.com  Read 11.1.
Tues 2/21:    HIV/AIDS history and science.  Vaccines and vaccination.  Monoclonal Antibodies. Immune Quiz on Wed 3/1.
Thurs 2/23: Antibiotic Lab due through turnitin.com. Review for Immune Quiz.  Dissect Chicken Wings.  Types of bones and joints. Read 11.2.
Mon 2/27:  Group IV Project.  All IB science testers who have not done this yet MUST participate!
Wed 3/1:  Immunology Quiz.  More on the elbow joint and start muscle fibers.
Fri 3/3: Actin and Myosin.  Structure and function of muscles!
Tues 3/7:  Final Draft of IA due through turnitin.com.  Structure of the kidney and the active unit of the nephron.  Read 11.3.
Thurs 3/9:  Ultrafiltration in the kidney!
Mon 3/13:  Hormones and start reproductive system anatomy.  Read 6.6.
Wed 3/15 and Fri 3/17:  More reproductive system!  Read 11.4.
Tues 3/21:  Big ole' review for muscle, kidney, hormone, reproduction test to be taken on Thursday 3/23.
Thurs 3/23:  Big ole Test!  (This is the last unit test we will take).  Please Read Option A in the book on Neurobiology and Behavior over Spring Break.
SPRING BREAK!!
4/3,4/5, 4/10,4/12, 4/14:  Option A Material!!
4/18:  Practice Paper 3
4/20:  Practice Paper 1

IA Guidelines

I recommend that you look at your book in pages 708-712 for more on what IB says about science Internal Assessments.  Here are the basic categories and some guidelines:

Personal Engagement (2 points):  Assesses the extent to which you engage with the investigation and make it your own.  Can be seen through thinking independently, creativity, addressing personal interests, and/or presenting scientific ideas in your own way.  Even though I saw what you did in your lab, you need to make sure that your write-up explicitly demonstrates your engagement.  I am not looking for a specific section of your lab that is labeled "personal engagement", but hopefully your interest and perseverance are clear throughout.

Exploration (6 points):  Assesses the extent to which you establish the scientific context for you work, state a clear and focused research question, and use concepts and techniques appropriate to the course you are studying.  You should also address how you considered safety, environmental, and ethical issues.  In this section, I am looking for good background, focused question, defined variables, and a well thought-out methodology that explains why and how you did things, being specific!  Make sure that you clearly state how you controlled your variables.

Analysis (6 points):  Assesses the extent to which your report provides evidence that you have selected, processed, analysed, and interpreted the data in ways that are relevant to the research question and can support a conclusion.  This section includes your raw data presentation, including labels, units, and uncertainty.  You need to have qualitative data (observations) as well as quantitative data.  It also includes any data processing, including equations, a sample calculation of each, well-presented graphs, etc.  Finally, you need to have written interpretation of your data, referencing it specifically to back yourself up.

Evaluation (6 points):  Assesses the extent to which your report provides evidence of evaluation of the investigation and results with regard to the research question and wider world.  State a detailed conclusion that is described and justified and relevant to the research question.  Make a comparison to the accepted scientific context if relevant.  Discuss strengths and weaknesses of the investigation.  The weaknesses can be listed in a table as source of uncertainty or limitation, implication to the results, and realistic suggestion for improvement.

Communication (4 points):  Assesses whether the investigation is presented and reported in a way that supports effective communication of the focus, process and outcomes of the investigation.  Writing should be clear and checked for spelling, grammar, etc.  Tables should be well-organized and paper should flow clearly.  Use appropriate biological vocabulary.  Paper should be between 6-12 pages long.  There is a 1 pt penalty for going over 12 pages.

The Beginning of Your Last Semester of High School!


  • Mon 2/6:  Look at Final Exams.  Some notes on the Respiratory System.  Data-based questions on the respiratory system done in your notes (p. 312 and 318).  Read 6.4.  Work on internal assessments?  Clean up the lab.
  • Wed 2/8:  More notes on the Respiratory System.  Finish reading 6.4.  We will have a respiratory system quiz on Tuesday 2/14.   Guidelines for completed Internal Assessment write-up, due Thursday 2/16 through turnitin.com (with some flexibility for students who are still trying to get data).
  • Fri 2/10:  Review the respiratory system.  Start Immunology by plating bacteria and testing antibiotics.

Semester Final Grades for 5th and 6th Periods

Hello Students!
I just entered Final Exam scores for 5th and 6th Periods.  Please note that I have not read Extra Credit book reviews yet and I am not likely to until tomorrow at the earliest.  All extra credit will be added on to the final percentage that you see.  Also, I will go back to the Internal Assessments and enter points for those.  If you have not yet submitted yours, I would do that now!  
Enjoy your week-end and stay safe out there!
Ms. Kenny
