Is Today Thursday?

ABOUT THE TITLE:

I totally think this week went by REALLY quickly, and I was writing the title for Wednesday (whoops) but then I fixed it, and changed it to this. Creative, huh?

BACK TO CLASS:
So in class today we first watched a movie about the populations of the earth, and how the number rose through the years (like, thousands of years.)
Today you had to turn in your narration/bibliography sheet and stamp sheet. (Also if you didn’t finish the table from the notes, you were able to turn it in today.) Then we did some notes

RECAP OF NOTES:
We talked about the human population and Biodiversity. All species on earth are involved in the food web. Also the threats of Biodiversity caused by humans are:
- Habitat destruction
- Hunting
- Pollution
- Invasive Species
- And Global Warming
Pollution
- DDT is a non-biodegradable pesticide (Biodegradable means it can’t be broken down by natural metabolic processes)
-Organisms can’t eliminate DDT from their bodies.
Biological Magnification:
-Pollutant concentration increases higher in food chain.

We were not able to go further into our notes (Due to talking about penguins)
We also watched a video called 60 minutes. It talked about how old computers are shipped to Hong Kong and are being scrapped and recycled, and how the harmful chemicals that they are burning are the most poisonous compounds known to humans.

HOMEWORK:
Skim 5.3 in book, make sure you can understand the main ideas and diagrams before the test on Tuesday. Read page 161 in book, and upload the oil spill movie to the blog BY FRIDAY BEFORE 8:00 AM!!!!!



THERE IS A TEST TUESDAY!!!!!!! (9/28)

Bee Tee Dubs:
I seriously think Mrs. Stein should consider having a class period where we ask random question about science. It would rejuvenate us into actually staying on topic in class. AND I told buffalo wild wings that they have a bison on there logo, not a buffalo. The waiter looked at me like I was stupid. hahahaa
