pgs 101-105 what goes there????

Just as a review of what goes on pages 101-105

101 -- SSA of objectives for entire year (yes you have to fill out the SSA to get the points)
102 -- printed picture of your dissection animal
103 -- drawing of what you actually saw when you dissected your specimen with observations
104 -- reflection of what you learned and why dissection is important in a Biology class
105 -- reflection of the class as a whole (from August until now)


GRADES are updated as of 4:00 on Thursday.  You can turn in your notebook with revisions through Tuesday (but really the sooner the better!!!)

pgs 102-105 are the PBA (final) for the semester

Dissection week

Now that the AP test is finished, we are going to take the week to do dissections :)
We have
  • crayfish
  • perch
  • fetal pigs
  • rats
  • clams 
  • grasshoppers
Pick at least 1, research what you should find within the specimen.  Sketch or print a "ideal" specimen, label all the parts.  Complete the dissection, sketch what you actually see.  Write a reflection on the entire process.  You have the week to complete.

pg 100 objectives for the ENTIRE class :)

Another booklet to go on pg 100 (or 101 so that it opens with the book) that gives you all of the objectives in one place to help in your studying this weekend ;) 

Click here for a PDF if you want to see it before Thursday

pg 98 practice data questions packet

the entire packet goes on pg 98, please look through and complete the problems to practice for the test! :)

pg 91 Chi Squared data



Procedure:
1) Look into the bag and determine how many colors are present and write them into Table 1
2) Without counting, estimate the number (percentage out of 100%) of each color and write them into Table 1 under "Percentage Expected"
3) Sort the candy and write down the number of each color into Table 1 under "Number Observed"
4) Complete the table by determining the total number of candies and number expected columns


Color of Candy
Percentage Estimate
Number Observed
Number Expected
(total # of candy x percentage estimate)





















Total # of candies =

pg 90 Chi Squared



This information should be on page 90


Chi Square (Χ2) Modeling using Candy
The Chi Square test is often used in science to determine if data you observe from an experiment is close enough to the predicted data.  In genetics, for instance, you might expect to get a 3:1 ratio if you crossed two heterozygous tall plants (Tt x Tt).  Calculating the Χ2 values help you determine whether the results follow the prediction and if the variations from the exact ratio are due to random chance.  It’s the question of “how close is close enough?” If the numbers differ greatly from your expected results, then it’s possible that other factors may be influencing your results.
A chi square analysis requires a scientist to propose a null hypothesis and an alternative hypothesis.  IN statistics, the only way of supporting your hypothesis is to refute the null hypothesis.  IN other words, rather than trying to prove your idea right, you must show that the other idea (hypothesis)is likely to be wrong.  That is your NULL hypothesis.
Chi square values are used to show that the likelihood that the outcome is due to random chance is very unlikely.  An alternative hypothesis can never be proven, data can only reject or fail to reject the null hypothesis.

pgs 86-89 Notes from your plan on page 84

Page 84 should have the two modules you picked from education portal and also a plan for learning the information within.  Pages 86-89 are where you can write or tape in notes that you have taken from those two modules.

pg 84 Education Portal

Go to the AP Biology page on Education Portal

Pick 2 areas where you feel you need more time with.

On page 84 write down the two areas that you picked and make a plan for the next three weeks of how you are going to learn more about these areas (outside of class)

The AP Biology test is 3 weeks from today (it is Monday May 13)

Wednesday stuff

Finish up the questions from Monday.
If you are done, then go to this link
education portal

This has information on all objectives that will be tested on the AP Biology test.  Pick an objective that interests you or one you feel that you need more information on.  Follow the links and learn :)
Take notes on the next 2 pages (which should be 82-83)

Information for Monday April 22, 2013

Get a computer and turn it on
Tape the last ACT practice questions on the next 3 blank pages (pgs 74-76 ish???)

Take about 15 minutes (5 for each prompt) to read and answer the questions.  The sub will go over the answers.  

(the answers for Passage V are B, H, C, J. A. J)

On pages 79-81 ( or the next 3 blank pages after the ACT practice stuff) answer the following questions.  If you need to research the answers, do that.  All answers should be complete thoughts (bullet points are fine as long as I can tell what you are talking about -- you should have a minimum of 3 ideas or bullet points per question)
  1. What are the advantages of asexual reproduction?
  2. What are the advantages of sexual reproduction?
  3. What are some different types of asexual reproduction?  Give examples of organisms that perform asexual reproduction.
  4. What attributes (characteristics) are used to pair homologous chromosomes (how do you put together chromosomes to make a karyotype)?
  5. Why is it necessary for gametes (sex cells) to be haploid?
  6. How many chromosomes does a normal human skin cell have?  How many chromosomes does a normal human sperm cell have? (for the question you can have 2 bullet points)
  7. How can you tell the difference between a karyotype of a normal human male and a normal human female? (one bullet point is sufficient here)
  8. Describe at least one situation in which it would be beneficial for a person to have his or her karyotype examined
  9. If you observed a human chromosome spread under the microscope and discovered that the sample contains 47 chromosomes, what would you conclude from this observations?
  10. What disorder would you assign to a human karyotype that contains three chromosomes in the 21st location?

Cancer out of control cells & a few more resources for info on the cell cycle

Click here for a short article on Cancer.  There are questions at the end that should help deepen your understanding of Cancer and how it relates to the cell cycle (info should go on pages 58-59)

Fix notebooks

Work on existing pages to have a better understanding of learning objectives for the cell cycle. Once you have evidence that you have interacted with the material more, you can re-take the test. 

Retakes will start on Monday :)

pgs 63-64 Meiosis only information

pg 63 may have some information about mitosis vs meiosis, but is should also have info on just meiosis (probably the table shown below)




pg 64 labeled drawings of meiosis (see picture below)

pg 62 Mitosis vs Meiosis

What is the difference between mitosis and meiosis?  (and why really did biologists name two similar processes so . . . .similar?)

Mitosis vs Meiosis t-chart

Click here for a NOVA animation to help with the differences.  

Please take notes on page 62 (from the above resources)
 
Really corny animation and song!  Meiosis square dance 

Take this quiz and e-mail the results to me (and to yourself)

Nova: Can we live forever? (and do we want to?)

As we now know about the cell cycle, the question becomes, why do we care about it and what sort of scientific advances are being made because of our knowledge?

Today we watched a NOVA: Science NOW episode called "Can We Live Forever?"

Test on Cell Cycle objectives Tuesday!!!!

Cell Cycle objective test (see post from Monday March 25th) on Tuesday

You will be allowed ONE 3x5 notecard (front & back) for the test.

Couple of things to consider when studying for the test
  • Use the Mader Chapter 9 resources (including the post-test)
  • There will most likely be one "calculation" type question on the test (use Campbell Bio Chapt 8 thinking like a scientist to help with that)

Cell Cycle info

You will have through Friday to work on the cell cycle learning outcomes (see previous post).

On Tuesday April 2nd, there will be a test on these outcomes.  The test will be very similar to the test found on the Mader site for chapter 9 (click here for the site)
