3/21 Biology Class and homework due 3/28

Hi folks,

Today in Biology we took a fairly in depth look into how energy moves through an ecosystem. We discussed food chains, food webs and biogeochemical cycles. We also took advantage of the wonderful weather to play a game that emphasized some of the hardships of being a part of a food chain.

Homework for next week:

Read pgs. 366-369
Questions 10-17 on page 376

Slight change to biology homework

Question #4 got spell checked the wrong way and I didn't catch it. Sorry. Here is the correct question.

4. What does competition mean when it is applied to communities?

Link to Biology Recording for 3/14 - Community Interactions

Hi folks,

Biology update 3/14 and homework due 3/21

Hi folks,

Today we discussed ways that different species interact in their community.  Unfortunately the book really doesn't cover this material so I'd like you to go to this page and read each page until you get to "Ecosystem Energy Flow".  After reading the material, please answer the questions below.

Also, go to the following web page and do the activities there.  Please write on a separate sheet of paper what the "journal" asks you to write on the screen.

Fwd: Some Birds Are Just As Smart As Apes – Neuroscience News

Hi folks,

Here's an interesting article about the intelligence of crows I thought you folks might find interesting. Turns out, they are really very smart and researchers aren't sure why.

2/29 Biology update and homework due 3/14

Hi folks,

Just a reminder, next week is Spring Break so we will not be having class next Monday.

Today we started a unit on basic ecology. We discussed different methods of animal behavior and how individuals interrelate with their environment and the organisms within that environment.

Homework for this week is to:
Read pgs. 359 - 365 in the book
Answer questions 4-11 & 25-26 on page 376
