Work with class on UP page 13
Discuss natural selection lab UP pages 17-19
Engage in superduper fun natural selection lab UP pages 17-19

Today's class started off by handing in the unit packet pages 4-8. We then took a gander at Delia's scribe which then left me with some tragic news at the end. Anyway, after that Mrs. Stein went over the green sheet that goes along with 16.4 for homework. We then worked briefly on page 13 in the unit packet as a class. We had to tell whether the sentence went along with Darwin, Lamarck, neither or both of their theories. After, Mrs. Stein then described to us what was needed to do for the natural selection lab. (UP 17-19) Finally the class split up into their groups and worked on the lab. The natural selection lab shows how the environment determines what species survive and which ones die out. In this case the dots who camouflaged with the cloth were the ones that survived.

Friday's In The Lab!

Today was a pretty good friday, we actually got out of our seats!

First, we did a star and wish for Dana's blog. Next we took notes on the Greenhouse Effect, below i displayed the notes I took in class.

Notes:
Greenhouse Effect - Natural situations where heat is trapped by CO2 methane and other gases.
-Results from burning of fossile fuels and forrests.
Effects of Global Warming:
- Rising of sea levels
- Loss of Biodiversity
- Natural Disasters
Ozone Depletion:
- A layer of O3 gas in the atmosphere
- Filters harmful UV rays (sunscreen for earth)
- CFCs caused hole in ozone layer
- Use of aerosol cans containing CFCs banned in 1987
- Ozone holes are Shrinking!

After taking notes Mrs. Stein considered showing us another 60 minute video that was about 15 minutes long but instead we decided to go straight to the lab. Once in the lab we each sat at a computer, logged on to our moodle accounts and started watching and commenting on eachothers oil spill videos. After watching the videos on the blog, some people started part of the homework while others who couldnt upload their videos recieved help from Mrs. Stein.
Below is the homework from Friday.
