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.
Homework
Up 4-8
