Agenda

Hand in double bubble map

Finish discussing Darwin

Breakfast for Birds

Today class started off by everyone handing in their double bubble maps.

We took notes about Darwins Assumptions, Variations, and Descent with Modification.

Darwins Assumptions

(based on his observations)

- Over production

* More offsprings are produced than will survive.

(For ex: producing a lot of eggs)

-Struggle for existence

* Predation and competition

-Survival of the fittest

* Individuals best suited to the environment will survive, reproduce and pass on the traits to their offspring.

(Meiosis- genetic variation gives natural variation)

-Variation

* Differences among members of the same species

-Descent with Modification

*Principle that species change but descend from common ancestors.

After note taking we began a new lab.

Mrs. Stein gave us all a brief understanding of our lab BREAKFAST FOR THE BIRDS.

-There were five stations

1) Log (rice)

2) Pond ( foam pieces)

3) Field (sunflower seeds)

4)Rocky ledge (staples)

5) Worms in grass (rubber bands)

At each lab station there were pliers, forceps, spoon, and a staple remover ( one of each tool).

Each person used ONE tool to collect as much "food" as they could with that tool. Each tool represented the beaks of a bird.

At the end of each session each person had to count how much "food" they collected with their "beak" (tool) and the group had to collect their data as they moved around to each station.

After the lab was completed Mrs. Stein explained our homework (the graphing part of it).

It was simply graphing your data onto a bar graph to analyze and compare the results.

Fridays Class

Fridays class had a sub. In the beginning of class we got our home work checked in for a stamp (UP- 12). After we got our homework checked in we went over it. We specifically discussed problems 8 and 9 because some people had difficulty answering those problems. After we talked about homework we talked about Influenza.

Influenza

• Virus
• endemic/respiratory infection transmitted by casual contact
• treatment for symptoms only
• prevented by vaccines and sanitation
• 40,000 in u.s year
• one million world wide

After discussing Influenza we went over the lab (UP 13-18 ).

Lab: How common are bacteria and how quickly do they reproduce?

The purpose of this lab was to learn about sterile techniques, expose nutrient agar to 3 objects to determine if bacteria are present on the objects, observe bacterial colonies on your agar plate, evaluate your sterile techniques and determine places where bacteria are likely to be found.

The four objects/surfaces my group tested were, 1- Locker, 2- water fountain, 3- top of a hand sanitizer bottle and 4- was unexposed.

The picture above is an example of what the trays looked like only our trays were cut in fourths.

Homework

UP 13-18

Post card 11/8

READ 20.3 w/ double bubble map "Bacterial vs. Viral Disease" - Monday

Friday September Third.

Friday September 3rd.

Today second period Bio started off with checking in the homework (“check my understanding chart”). Then we discussed the lab write up which is due September 8th. Mrs. Stein explained to the class that we should use a creative title for our lab write up because it’s important. After discussing the lab write up we then talked about the “Cornell Notes” which was part of our homework assigned. If any troubles understanding you can look at the guide which is posted on Moodle. Today we dived into a new unit; Ecology. In class we listed some examples that make up the ecosystem, our class came up with examples such as…nature, all living things, plants, bacteria, maintaining balance and what can disrupt that balance. Mrs. Stein gave us a brief understanding of our next assignment on a slide show that we are going to have to narrate. Finally, for the last half of our class, we went outside on an “Ecology Walk”. We had to list several producers and consumers that we saw on pages 13-14 in our packets. To wrap up the class period we talked about what we observed outside.


Homework:
Read 3.1-3.2 - “Cornell Notes” – Tuesday
Visit for Homework Pass 9/1 (Tuesday)
Finish up pgs 13-14 (if not done in class) –Tues
Lab write up-9/8 (Wednesday)
