Mesocosm Write-Up

One of the 7 required practicals for IB Biology is to study a mesocosm in the classroom.  This year we made 4 mesocosms.  The first 2 were made on Monday 9/11 using water, plants, and critters from Commonwealth Lake in Beaverton.  The other 2 were made on Wednesday 9/13 using water, plants, muck, and critters from Whitaker Ponds in Northeast Portland.  Your job is to make consistent observations from at least 2 of them, although you can use observations from all 4 in your write-up.

The write-up is due Friday 9/29 through turnitin.com and should include:

1. Detailed observations from at least 6 separate days.  Include water clarity, condition and growth of plants, types of animals, behavior of animals, condition of muck and other debris, etc. Make it clear which mesocosm goes with each observation and which day.  You can include details about the classroom conditions (temperature, light, etc) if you think they are relevant.
2. Use vocabulary from the ecology unit to try to explain what you think is happening in the mesocosms.  For example, information about cycles, energy, and types of nutrition would be appropriate.  You don't have to know exactly what is going on or know the names of the organisms, but do your best to give reasonable explanations.  If you use outside information in your explanations, state where or how you got the information.
3. Predict what you think will happen in the mesocosms, giving a reason for your predictions.

I expect that a good job on this assignment will take about 2 pages of writing, although it is the quality and ideas that count, not the quantity.

Turnitin.com Info

Every year we get a new class ID for turnitin.com.  Turnitin.com is used for turning in most written assignments in this class, including labs, SPARK lectures, mesocosm write-up, etc.

1. This is in 3.1. What is a gene?
2. Where are genes located?  Draw a diagram to help explain.
3. Look at the chart on p. 142 that compares numbers of genes in different species.  Which species has the most genes?  The least?  How many genes do humans have?

5. What are alleles?  Describe the differences between different alleles.  Where do these differences come from?
6. Do the DBQ on p. 145.
7. Read the section on sickle cell anemia and outline the genetic change that causes sickle cell and what it does to the blood cells and health of people suffering from sickle cell.

17. What is the difference between a haploid nucleus and a diploid nucleus?  Use humans as an example.
18. Explain why different species have different numbers of chromosomes.
19. Do the DBQ on p. 156.
20. What is the difference between an autosome and a sex chromosome?  How many autosomes do humans have?  How many sex chromosomes?
21. Discuss how the sex chromosomes determine sex in humans.
22. What is a karyogram?
23. How can karyograms be used to determine sex and diagnose chromosomal disorders in humans?
24. Do the DBQ on p. 159.

Semester Grades

Hello Students!

I hope you all stay safe today in the ice!  As many of you have noticed, I entered the final exam scores last night.  I have not entered extra credit yet and I can really only add that to the finalized grade, so you need to hang tight!  You can tell how much extra credit you are getting by looking at your SPARK lectures and book reviews in turnitin.com.  I probably won't get around to finalizing grades until Sunday or Monday (they are due Tuesday).  I still have a lot of work to do for my 2nd year students.  Please try to relax and enjoy your week-end!

Ms. Kenny

Short Quiz on Cell Division, Mon 1/23

1) Be able to identify cells in phases of mitosis and interphase (onion root tip cells)
2)  Be able to describe events of cell cycle from interphase, through all phases of mitosis, and cytokinesis.
3)  Be able to distinguish between cell division in prokaryotes and eukaryotes.
4)  Be able to ""                ""               ''                     plant cell and animal cells.
5)  Be able to briefly describe how cyclins control the cell cycle and why knowledge of this is important!

Post-Snowpocalypse!!

Well, I hope we have those snow days out of our system now.  Here is the plan for the end of the semester:

• Thurs 1/19:  Notes on the Cell Cycle.  Finish the cell cycle worksheet and get it checked off.  Go over Onion Root Tip Pictures from On-line Game.  Cell Division Quiz on Mon 1/23.
• Mon 1/23:  Short Cell Division Quiz.  Start Reviewing for the Final Exam:  a little bit of statistics, cells and membranes.
• Wed 1/25:  More review for the Final Exam:  water and biochemistry.  Cell Respiration and Photosynthesis.
• Fri 1/27:  All late work must be turned in by today.  Kahoot Review for the Semester Exam.  Any last questions??  
• Mon 1/30:  All book group reports must be turned in through turnitin.com by 6:00 pm today.

First Weeks Back!!

• Wed 1/4:  Review Cellular Respiration and Photosynthesis.  Start Cell Division.  Look at Khan Academy site on mitosis and watch Blood Lily Mitosis.  Start working on Cell Division Worksheet.  1-11 due by next Monday.  Start reading 1.6.
• Fri 1/6:  Take Cellular Respiration and Photosynthesis Test.  Continue working on Cell Division Worksheet up to and including question 11.  If you finish that, read pages 56-59 on cyclin control of the cell cycle, tumors, cancer, and smoking.
• Tues 1/10:  At your table use string,yarn, and other materials to simulate binary fission and mitosis.  Get teacher check off.  Look at microscope slides of onion root tip mitosis phases.  Practice calculating index of mitosis.   If done today, turn in Cell Division Worksheet.
• Thurs 1/12:  Notes on control of the cell cycle and cancer.  Data Based Question on pp 58+59 done in notes.  Start reading 10.1 on meiosis
