In Biology class on Wednesday (yesterday), we started off by turning in our homework; which was the Rip-O-Meter lab write-up, and the "Picture This!" homework assignment. Then we took notes in class about the following:
Pyramid of Energy: 10% of the energy at one trophic level is available to the organisms at the next level.
Biomass Pyramid: This contains the amount of living tissue and thus, potential food. Also note: The greatest biomass is at the base of the pyramid.
Pyramid of Numbers: Relative number of individual organisms at each level. In certain ecosystems, it is not pyramid shaped.
We received two images to tape into our journals that explained these notes. Mrs. Stein will most likely give these to you if you were absent during this class.
Then, after taking our notes, Mrs. Stein described an upcoming assignment to us.
Viewpoints on the Gulf Oil Spill: In this assignment, we each will have a partner (which you can chose), and you work together on this assignment. The first part of the assignment is to bring at least 10 pictures (EACH: both you & your partner!) to class on Tuesday as a part of a homework assignment. The assignment for the Gulf Oil Spill is to pick a point of view that relates to the Oil Spill and do research (I'm assuming sometime next week).
Then, more towards the end of the class period, after picking partners, we opened up to our Unit Packet page 21, and had to discuss this with our partners: A small group of people are stranded on a barren desert island. They have 500 bushels of wheat and one cow. What should they do to survive for the greatest length of time? This question, and answering the questions on UP Page 21 carried us until the end of class.
Homework:
"Get on Blog.
Read 4.3 and do the double bubble map [primary vs. secondary succession]
due on Friday.
Oil Spill Pictures, 10 by TUESDAY."
Note: For those of you who don't know how to do the double bubble map, visit this link: http://gbs-moodle.glenbrook225.org/moodle/file.php/1521/Reading_Strategies/Double_Bubble_Map.pdf
