1. NEURONS!

2. 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

3. 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

4. NEW UNIT:
Construct an argument supported by empirical evidence that
changes to physical or biological components of an ecosystem
affect population
AND…
Evaluate competing designs for maintaining biodiversity and
ecosystem services

+

5. Ecosystem Complexity
Ecosystems are much
more complex than
you would think.

6. 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? ??

7. 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?

8. Test Discussion
How many people are studying after the last unit’s test?

9. 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.

10. 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.
