Unit+1-Evolution

Wednesday, September 25, 2013
Today you brought in a graphic for your article and discussed it with your group. Together, you created a new graphic. Bring a copy for each group member with you tomorrow. Tomorrow you will peer evaluate another group's graphic. You will also have Friday to complete the Jae. It is due on Monday when you come to class. Remember to see COB for details about what should be in the JAE. NO VOCAB QUIZ THIS WEEK!!!

Monday, September 23, 2013
Today we took the Evolution Unit Exam. You should get it back tomorrow. Homework is to read the JAE article you received and annotate it. Some tips on annotating: Underline unknown terms--look them up and write definition Write a BG by background info Write an IV by passages that dipict the independent variable. Write a DV by passages that dipict the dependent variable Write a CV by passages that show what variables were controlled Write ES by passages describing how the experimental and control groups were set up Write a P by p values Write a C by conclusions

This should help you. The articles are not easy to read, but you can do it:) This is the assignment we get the most positive feedback about from college students because it is a very useful skill that sets them ahead later.

Today we took Vocab Quiz 3 Test Monday! Use your targets, book, wiki, notes and activities. Here is the powerpoint that goes over the mistakes on the Post Lab Quiz Mr. Erdmann will be in 1904 if you have questions bewteen 7:30 and 8 on Monday.

Thursday, September 19, 2013
Today we presented the results from the Teddy Graham experiment. We also went through the following powerpoint: Vocab quiz 3 is tomorrow.

Also, the bonus assigment described about 2 weeks ago is due tomorrow. PAPER COPIES only.

Today we did part 2 of the lab. You also turned in the M and M lab analysis. Each group violated one of the Hardy Weinberg tenants. Tomorrow we will find out the results. Homework is to finish the Google Doc lab report and be ready to present tomorrow. Also, start looking at the targets and reviewing for Monday's test. Vocab quiz 3 is Friday.

Tuesday, September 17, 2013
Today we did part one of the Teddy Graham lab. If you were absent, get data from a group member. All groups accepted their null hypothesis, because in part one, all of the Hardy Weinberg tenants were in place. (large population size, random mating, no mutation, no immigration or emigration, and no natural selection). Tomorrow you will do the simulation while violating one of the tenants. We also discussed the Post Lab quiz. I couldn't give it back due to a student that hasn't taken it. As soon as he has taken it, I will hand them back and post the powerpoint that we went through in class discussing the answers. In addition we went over the Genetic drift quiz and cladogram (fruit) packet. See me if you have questions on either.

Monday, September 16, 2013
Today we did the Chi Square M and M lab. Attached is data for one class. If you were absent, use this data to do the lab. Lab due Wednesday Remember, Chi Square is used to determine whether observed and expected values are the same or different. The chi square value can be looked up on a chart to give you a p Value. If the p value is less than .05, then the numbers are so different, that the difference is significant and not due to chance. If the p value is greater than .05, then the differences are smaller and they are likely due to chance.

Tomorrow, the prelab for the Hardy Weinberg lab is due. It was posted in Friday's blog. This link may help you: [|Hardy Weinberg help] One difference is that we don't have a dominant or recessive allele. We are using Honey for p and Chocolate for q.

Today we conducted the Genetic Drift Simulation. If you were not here, you can do it at home on your own using any type of bean or beads. You just need three different types. If you cannot do it at home, get data from a classmate. You do have to make up the very short pre-lab assessment in the testing center. Also, if you were absent, turn in the fruit cladogram packet on Monday. The M &M prelab is due on Monday along with the Bioinformatics lab. Turn in complete answers to the questions for the lab on separate paper with part of the question in the answer and turn in a copy of your aligned sequences and cladograms. Be sure they are labeled.

Here is a handout that will be given out MONDAY. However, since some of you might have time this weekend, if you want, you can print it out yourself and do the prelab. This prelab is due Tuesday.

Thursday, September 12, 2013
Today was a late arrival day. We took Vocab Quiz 2. If you missed it, take it in the testing center ASAP. You picked up 2 handouts: The prelab for this one (genetic drift simulation) is due tomorrow.

The prelab for this one(Chi Square) is due Monday. DO NOT BRING M&Ms. You can cross that off.

The Bioinformatic Lab analysis is due Monday as well.

Wednesday, September 11, 2013
Today, we did the Bioinformatics Lab. I gave out the following new lab: Complete parts A and B for Monday. Turn in the answers to the questions in complete sentences and with part of the question in the answer along with the aligned sequences, and phylogenetic tree. Be sure to label which part (A or B) each item is from. Here is the powerpoint with the updates for the lab instructions:

Today we worked on making cladograms from derived characteristics. This is the packet handed out yesterday. You need to complete this packet by Thursday. You will turn it in then. For tomorrow complete the Biology Bioinformatics Pre-Lab--Pages 1 and 2. You will turn this in tomorrow. Also, make sure you have set up an account as stated on page 3 of the packet.

Monday, September 9, 2013
Today we took the Behavior Post Lab quiz and began discussing cladograms. Homework is to read the fruit cladogram activity that we are doing tomorrow. It is a good idea to watch the video cited in the lab also. [|Cladogram explanation]

Don't forget the bonus assignment described on 9/5 of this blog is due on 9/20.

Friday, September 6, 2013
Today we discussed how to write a hypothesis, sources of error and the results from part B and C.

For writing a **hypothesis**, use an If....then statement and a **quantitative** statement. For example, If 10 pill bugs are put into a choice chamber that has a wet and dry side, then after 10 minutes, at least 6 pill bugs will be on the wet side.

As to part B and discussing error, we saw that in most groups, the bugs preferred the moist side, however, sometimes, they preferred the dry side. Also, sometimes, there was a bigger difference in the control trial than in the experimental. In these cases, a preference for moisture could not be assessed. However, we KNOW that pill bugs prefer moisture--they have gills and need water to get oxygen so they can survive to reproduce. So why the data not all show this??? Sources of error: some bugs crawled under the dry paper. This provided a dark environment, which pill bugs also prefer. If they did not do this, likely more bugs would have been on the moist side. Also, some bugs were wet when they were put on the dry side. This made the dry side wet. Again, if this did not happen, likely more bugs would be on the wet side.

As to results of part C, we found that the bugs prefer dark, slightly acidic, sugarless, cool environments. Each group discussed errors that occurred as well.

No School

Wednesday, September 4, 2013 Today you completed part C of the lab. Each group chose a different Independent Variable to test. Friday, we will discuss the results. I also gave you feedback on your graphs--a few things to remember: Title the graph using " The Effect of the //IV// on the //DV// over //some unit of time, "// label all axes with units, be neat and clear in your axes labels and keys, make the graph large.

Bonus assignment--Due 9/20 Research an Invasive Species Find an example, or evidence of one somewhere around here Take a picture of you with the example or evidence Write the name of the species--common and scientific State where it is from Describe the damage it does--why is it a problem?

Nothing due Friday. Post Lab quiz on Monday.

Tuesday, September 3, 2013 Today we took the Pre-Lab Quiz and did part B of the lab. Each partner set did one control and one experimental trial and shared data with 3 other partner sets. Homework: Average data for each of the two control sides and for the moist and dry sides. Graph this data. Graph should have 4 lines: One for side a control, one for side b control, one for dry and one for moist. The y axis is number of bugs on each side while the x is time. Note--DO NOT plan for part C yet.

Thursday, August 29, 2013 Today we took the vocab quiz. See me ASAP to make it up if you were absent. Homework is to finish the Evidence for Evolution Packet.

Wednesday, August 28, 2013 Today we discussed modes of selection as well as Evidence for Evolution. Complete the packet for Friday. Here it is if you lost it. If you were absent, do all except for the page about embryology. Tomorrow is the Vocab quiz for the prefixes and suffixes on page 18 in the COB. There is also a quizlet on the Course Wiki to help you review.

Tuesday, August 27, 2013 Today we discussed how bedbugs evolved resistance to pesticide. Here is one way to phrase the explanation: "In the bed bug population there was variation due to random mutation that made some bugs resistant to the pesticide, pyrethin. Once the pesticide was used by humans, this created selective pressure that favored the bugs with the resistant trait giving them a selective advantage. Those bugs with the resistant gene were more likely to survive to reproduce than those without it. This trait was passed on to their offspring. Over time, this trait became more frequent in the population and thus and adaptation that helped the bed bugs survive"

You then wrote an explanation in groups about a trait of the organism you observed on Friday. Then we talked about modes of selection. Homework is to read 22.3 and 25..2 in Campbell and complete pages 1 and 2 in the packet and on page 5 choose 1 example and complete letters A, D, and E about it. Please do B and C if you are able. We did not thoroughly talk about modes yet, so you may have trouble with B and C. Here is the packet:

Monday, August 26, 2013 Today we read an article about bedbugs. The questions are homework for tonight: We also discussed the bean/utensil lab. We discussed what factors determined survival of the predators and prey as well as the independent, dependent and controlled variables in the experiment. The IV was the utensil type, the DV was the number of predator and prey that survived. Some variables that should have been controlled, but were not were the ability of the person using the utensil (hand eye coordination), the amount of practice the person got, distractions in the room... Finally we went through this powerpoint: We will continue with the discussion of the organisms tomorrow. Again..homework is to finish the bedbug article and complete the notes from the book pages listed on the calendar.

Friday, August 23, 2013 Today we started thinking about the idea "Survive to Reproduce". We did two activities. We went outside to observe an organism and write about how it is able to survive and we did the natural selection lab. We will discuss both on Monday. Neither is homework. Homework is on the [|AP Biology Calendar]

Thursday, August 22, 2013 Welcome to class. Today you got the Course Outline Book, Targets for unit 1, Natural Selection Lab, and Access info for the text book. We got to know each other by making name plates and discussing a few things. . Here are the handouts:
