Tuesday, March 22 Scribe Post!

Today we started class by turning in our Flower Lab ( UP 41-44). Next we went over the Plant of The Day... which is called the "String of Pearls" (Senecio rowleyan). We learned that this plant is native to dry regions in south west Africa. It's leaf shape reduces the surface area to prevent water loss. It is also a "succulent" plant, which means that it is a water-retaining plant.

Immediately after going over the P.O.D, Mrs. Stein asked us if we had any questions about the Lab quiz that we had today. After reviewing for a couple minutes, it was finally time to take the quiz.

Then, after we took the quiz, we took a few notes about POLLINATION.

Here are just a few KEY points that we took notes on:

~Pollination is the transfer of pollen from anther to stigma.

~Self Pollination.

~Cross Pollination.

~Fertilization.

~Double fertilization.

~Coevolution.

~Cross Pollination methods

-Can be pollinated by wind and also a vector pollinator!

~Seed Dispersal

-Wind, Barbs that stick to animals, animals eat/excrete seeds.

The HOMEWORK is as follows:

-UP 45-46 colorcode.

-Read 704 & 705.

-PRESENTATIONS DUE TOMORROW Before 8:00 am!

-Weird plants practical test on Thursday.

-Plant TEST on Friday!!!

The Next Scribe will be............ Natalie!

Biology Class

Class: Wednesday, September 8th

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
