Warm-ups: November 12 – November 16

How does a species survive?

Monday, November 12, 2012• Choose a hypothesis for the Science Seekers

Lab activity and write it in your warm-up. Choose from the list below.

1.If there are fishing boats in the area, then the population of sea otters will decline because they will drown in nets.2.If sharks are in the area, then the population of sea otters will decline because sharks are predators.3.If there is pollution at Ocean Edge, then the population of sea otters will decline because it will cause disease.4.If there is competition for food, then the population of sea otters will decline because they will starve.5.If otters are exposed to PCB, then the population of sea otters will decline because of reproductive failure.

Tuesday, November 13, 20121. Define life cycle from the Science Seekers books• Use life cycle correctly in a sentence so the meaning of the word is

clear• Add a picture to help you remember the word 2. Define reproduction from the Science

Seekers books• Use birth rate correctly in a sentence so the meaning of the word is clear• Add a picture to help you remember the word

Wednesday, November 14, 20121. Write down what you remember about

migration from the Otter Cove game.

2. Watch the wildebeest video about migration:http://video.nationalgeographic.com/video/player/animals/mammals-animals/deer-and-antelope/wildebeest_migration.html

3. How does migration add or subtract from a population of a species?

• Write down the definition for limiting factor• Something in an environment that limits how

much a population can grow, such as the amount of food or space available, or the presence of predators.• As a group, each individual read about your

limiting factor and then summarize the information and add the examples to your definition.

• Finish Brain Pop Food Chain WS!

Tuesday, November 20, 2012The taiga ecosystem (Summit County) has lost it’s

population of mountain lions to a poisonous substance found in their bodies. • How will the elimination of mountain lions change

the ecosystem? • Name at least two changes to the ecosystem and

how this affects the equilibrium of the ecosystem.
