NEURONS!

Bell Work 1/30/2015

Explain in your own words how you think your invasive species might destabilize the ecosystems that it has been introduced to

People who earned 3’s and 4’s on their last test ONLY

Welcome! Itinerary

Invasive species discussion

Dual track activities today:

Test review

Food Web

Announcements:

To join class discussions on celly, check your Edmodo for the join link”

Today’s Learning Target:

I can visualize trophic interactions via a food web

NEW UNIT:

Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystemaffect population

AND…

Evaluate competing designs for maintaining biodiversity and ecosystem services

Δ = -+

Ecosystem Complexity

Ecosystems are much more complex than you would think.

Biological (Biotic) Components of an Ecosystem

Community - a group of interdependent organisms inhabiting the same region and interacting with each other

Population - A group of individuals that belong to the same species and live in the same area

?? What is the difference between a community and an ecosystem? ??

Invasive Species Discussion

Remember: You need to be an expert on YOUR invasive species in order to share out to other people.

What are some commonalities that we are finding between invasive species?

Can we draw any inferences between what happens when a NEW species is introduced to an ecosystem vs. a reintroduction?

Test Discussion

How many people are studying after the last unit’s test?

Test Review:

If you earned a 1 or 2 during your last exam, you are remediation today with a review sheet. No Kahoots, not socratives…you need to put in the time for repetition that you might not have during class.

Don’t rush. You do not finish reviewing until I have talked with you and are convinced that you are ready to retake the test.

Anything you need help with, track down your resident rocket scientist. If both of you are stumped, come find me.

3’s and 4’s

If you earned a 3 or a 4, there are 3 options:

1.) Food web activity (we will do this later for homework, so you might be able to get it done now)

2.) Ecosystems padlet activity: Open the padlet on your computer and add resources that are mentioned on the padlet.

3.) Resident Rocket Scientist – People at the review tables (1,3 and 5) will need assistance. You may assist people in their review, but you are NOT to do their work for them.
