Worms Worms Worms Worms

The Advanced Biology class is doing a unit on annelids and worms in particular. This is to commemorate our new class pets, a pound of red wrigglers! If you don't know much about red wrigglers, check out this link that tells you how valuable that they are.

Students should watch the video below a few times to familiarize themselves with the internal structure of the earthworm preparing for this week's dissection. Please leave a comment using the comment link below, letting me know that you viewed it to receive a point of extra credit in class.

Viruses Test Coming Up!

The biology class has been learning about viruses and the Swine Flu (H1N1) virus in particular. We'll be having a test on the information on Tuesday. Here's a link to a good description of the Lytic and Lysogenic cycles of viruses. Below is a cool computer animation that a group of high school students made about the lytic cycle with a T-4 virus invading a bacteria. Enjoy!

Is There Life On Mars?

In class, we've been talking about the characteristics of life.  Do you think that there's life on other planets?  NASA has been sending missions to Mars for years looking for life.  They've now found methane on Mars and believe that this could mean that there's life on Mars.

  1. What is methane?
  2. Why do scientists think it is evidence of life?
  3. Do you think that this proves life on Mars?  Explain.
