Today in class we did a flower dissection. Tomorrow we will be looking more closely at the non-reproductive parts of plants. To prepare, please read section 23.1 and take notes for a reading quiz.
*** G and D periods, you luck out, because tomorrow you have a guest coming to class. So... you will not need to complete this assignment until Wednesday (G period) or Thursday (D period).

Quiz, Dichotomous Keys and Plants
Because of Step 1 testing yesterday many students weren't in class and so they weren't able to take the quiz. In order to keep moving forward here's the plan for today:
If you took the quiz: You will complete the dichotomous key activity. Homework: Read and take notes on section 22.1 for a reading quiz in your next class period.
If you didn't not take the quiz: You will take the quiz in class. If you have time, you can start the dichotomous key activity. If you do not have time, it has been emailed to you. There are two attachments you will need to complete this activity (and a picture posted below).
The attachment titled "Tree ID_Student" are the leaves you will need for parts 3 & 4 of the worksheet. The attachment titled "Tree ID" is the key you will use for the leaves.
Since you will be completing the activity at home and will not be able to see your classmates, make a dichotomous key using the "creepy/crawly" things below. Click the picture to make it larger.
In addition, you will need to read section 22.1 and take notes for a reading quiz.

Folder 5: What did T-Rex Taste Like
Today students finished the webquest "What did T-Rex Taste Like?" It turns out that T-Rex is most closely related to the parrot, not the crocodile!
The blog archive has been relocated so you can easily find it to help you review for the final exam.

We started to watch the Great Transformation episode from the PBS evolution series. For homework click the picture below to link to a simulation from Richard Dawkins, The Blind Watchmaker to see how accumulating small change over time can lead to big results.
Take a screen shot of your 100th generation and email it to me. On a Mac, press "shift command 4" all at the same time. On a PC use the print screen button.

Origins of Life
Today students had a reading quiz on section 17.1 and took notes on section 17.2. Click the picture below to see a much better animation on the origins of life, than the video we watched in class today.
Tonight for homework, read and take notes on 17.3. Tomorrow in class you will be taking notes on 17.4 Please bring your books to class. The sickness has finally gotten the best of me, and I will not be there, but you will have a sub.

Attack of the Mutant Crickets!!!
Today students read a case study about microevolution in a specie of crickets in Hawaii.
"Attack of the flesh-eating parasitoid maggots!! Mutant mute crickets run rampant in tropical paradise!! The headlines may sound like a trailer for a cheap horror flick — but in fact, these sensationalist sound bites accurately describe the situation on the Hawaiian island of Kauai. The "flesh-eating parasitoid maggots" are the offspring of the fly, Ormia ochracea, which invaded Hawaii from North America, and the mutant crickets are the flies' would-be victims. The flies follow the chirps of a calling cricket and then deposit a smattering of wriggling maggots onto the cricket's back. The maggots burrow into the cricket, and emerge, much fatter, a week later — killing the cricket in the process. But this fall, biologists Marlene Zuk, John Rotenberry, and Robin Tinghitella announced a breakdown in business-as-usual in this gruesome interaction: in just a few years, the crickets of Kauai have evolved strategy to avoid becoming a maggot's lunch — but the strategy comes at a cost... " Want to read more or see the article with color photos? Click here.
For homework click the PowerPoint and take notes on the four components of microevolution. Use these lines in your packet next to the images for each of the four modes of microevolution.

How does Evolution Really Work?
Today we started chapter 15, which is on evolution. For homework, watch the video clip below and answer the questions in your packet.
We also watched a clip on the difference between a theory and a hypothesis.
Who was Charles Darwin? Your book gives some information on him, watch this clip to learn more.
