Due: Wednesday, 10/26/11

Your task is to create a podcast on a current event in biology.  The podcast must be between 55 and 65 seconds long. (no shorter, no longer)  Quality is important in this podcast.  Make sure the sound quality is excellent and that you have edited out any extraneous noise, retakes etc…  You may have music in parts of the background but be sure to obey copyright rules (only short snippets of a song).  Be sure to say your name, the podcast name (Science Snapshot), and attribute your source.  Also be sure to present the information in your own words.  Do NOT read an article to me or even plagiarize parts of the article – turn it into your own words or be clear that you are quoting a specific line.

Email me the file to my cswfleetwood email address given in class.  Do not send it to my charterschool email.  Include your source citation in the email (in APA format).  It must be an mp3 file.  Be sure to name the file using your name (lastname_firstname_period) or you may not get credit. (e.g. smith_john_G.mp3)  If you are using Audacity, you can follow these instructions to get the Lame encoder to be able to export as an mp3.

If you need help, come see me during an activity period this week.  No excuses related to technical issues.

edit 10/17/11: one online way to create a podcast is to use Aviary – you can read more at the following website: http://www.aviary.com/tools/audio-editor

Due: Friday 10/21/11 (via email)

 

Read the handout from Darwin’s Origin of Species given in class.  Use the handout to answer the following questions…

1. What is the phenomena that Darwin is attempting to explain?

2. What data does Darwin rely on for his argument?

3. What is the importance of domestic breeding in Darwin’s argument?

4. Outline the mechanism Darwin offers to account of the phenomena in question.

5. Describe the conception of species that Darwin holds. (Include whether or not species are viewed as malleable or fixed. What role does variation play in Darwin’s thinking about species?)

6. Describe the nature of the “force” (mechanism) that is responsible for the production of new species.

• On what does that force act?
• Is it internal to the species or external?
• What role do the conscious “needs” of the organism play in speciation?

7.  Overall, how does Darwin differ from Lamarck?

Read the book prologue and answer the following questions:

• all check and challenge questions
• Chapter Review: RI #11, UC #1, 2, 3, 10

You should answer these in a single section of your notebook. We will keep adding to this section as we go through the chapters.
