Admit Slip: What is evolution?
Objective: Students will take notes on Charles Darwin, Alfred Russsel Wallace, Jean Baptiste Lamark, Georges Cuvier, James Hutton, Charles Lyell and Thomas Malthus.
Homework: We now know that there are four major modes of evolution: mutation, migration, genetic drift and natural selection. Find one example for each of the four modes (one example for mutation, one for migration..)

How long ago did.....?
Today we created an evolutionary timeline and realized just how long ago things happened on the earth. Students took notes on a handout elaborating on some of the events on the timeline.
Homework: Answer the four questions on the handout. Please use a seperate sheet of paper.

Bioethics & You (Friday & Saturday Classes)
Students debated the ethics of genetically modified organisms (GMO's) using the case studies they read for homework (yes, I actually forgot to post the homework...sorry Mike H.).
Case Studies were taken from the High School Bioethics Project and included the following briefs:
1. Patenting Life: Chakrabarty (bacteria engineered to "eat" crude oil)
2. Patenting Life: Of (spliced) Mice and Men (the Harvard Oncomouse)
3. Food & Drinks: GM Wine (GM grapes that grow in Florida)
4. Food & Drinks: Starlink Corn (Corn made for animal consumption and ended up in the human food supply)
5. Food & Drinks: GM Coffee (Coffee that can be ripened by the addition of a chemical)
6. The Forest for the Trees: GM Trees for paper production
There are only 2 more classes before the final exam!
General Bio homework: Complete pages: 77,79,81,83,85 and 87 in the review packet. This will take you about an hour and is due in class on Monday

MySpace & Science?? Whhhhatt? Bruce, Mike and Paul take it to a new level
MySpace and school project are words I thought I'd never say in the same sentence, but Bruce, Mike and Paul proved me wrong (well done!). They created two MySpace pages, which are open for public viewing, one for DNA replication and one for transcription and translation.
Kali's Poster & Mike's Book
Kali made a great poster (complete with sequins and Cinderella stickers). This picture also shows the cover of Mike's book and some of the dragons students made for the dragon genetics lab.
Jess & Sayde's Project
Jess and Sayde used candy for their project. See how many differents types you can identify (HINT: there are more than five)
