Notetaking: How are ecosystems organized? (15 minutes)
In your notebook, write down each of the terms and definitions in RED *We are going to move SMALL scale to BIG scale Set up your notebook by writing: Date: August 31st, 2016 Topic: Ecosystem Organization, Biodiversity and Succession Learning Target: Predict how environmental change or biodiversity loss will affect an ecosystem
2
Bell Ringer Pick up materials for today (your notebook) Place your homework (from the Scientific Method lesson)in the top left corner of your desk where it can be checked. Answer the following questions in your notebook: How would it affect the environment if the plants and trees burned down? What happens if a new species is introduced into an ecosystem where it has never lived before?
3
What are we learning today?
Benchmarks: SC.912.L.17.8 Recognize the consequences of the losses of biodiversity due to catastrophic events, climate changes, human activity, and the introduction of invasive, nonnative species. SC.912.L.17.4 Describe changes in ecosystems resulting from seasonal variations, climate change, and succession. Objectives: Understand the value of biodiversity, and characterize threats to global biodiversity. Understand the levels of organization in an environment Analyze texts describing the effects of forest fire and deforestation on an ecosystem, and write a CER comparing the two.

Agenda Bellringer (5 minutes)
Announcements and Ecology introduction (3 minutes) Power Notes (15 minutes) Biodiversity activity (10 minutes) Our first CER! (20 minutes) Biology Pre-test (30 minutes)
5
Our goals today to investigate how ecosystems are organized,
what factors make an ecosystem healthy and productive what happens if a environmental change alters the conditions for an ecosystem. Here’s dramatic example of environmental change…while you watch I want you to think about how the surrounding land and things that live there would be affected.
7
An individual living thing
Organism An individual living thing
8
Members of one species inhabiting the same area
Population Members of one species inhabiting the same area
9
Community Two or more populations of different species living and interacting in the same area
10
The living and nonliving parts of an environment
Ecosystem The living and nonliving parts of an environment
11
All of the ecosystems on the planet
Biosphere All of the ecosystems on the planet
12
Biodiversity What is it?
The variety/diversity of living things in the world or in a particular ecosystem Why is it important? Provides a range of natural resources Increases productivity and resiliency of an ecosystem
13
Threats to Biodiversity *write after your definition of biodiversity
Habitat loss Invasive species Population growth Pollution Overuse/Overconsumption
14
What are Invasive Species?
Species that are introduced to or invade an ecosystem, usually causing economic and/or environmental harm often introduced by humans Why are Invasive species a problem? Disrupt food webs They have few predators Reproduce and spread quickly Outcompete natives for food and/or habitat (space)
15
Succession Timeline
16
In your notes… Primary Succession Starts with LITTLE or NO soil
Secondary Succession Starts with soil present
17
Biodiversity Activity
Our class is a tropical hardwood forest, a common habitat type in Southern Florida. You are all trees in the forest; you all play important roles in the ecosystem, like providing food, shelter, and keeping the air and water clean for the organisms that live in the forest. The card that you have been given tells you which tree species you are each round. Listen up for your tree name to be called as I call out certain scenarios that happened in this forest. We will go through 3 rounds Look at your card to see which tree you are each round. If I call out your tree name for that round, sit down in your seat. At the end of each round, everyone will stand back up and we will restart *there will be no moving about the room during this activity*
18
Round 1: A fungus, called the Laurel Wilt, is spreading through the Everglades and southern Florida. This tree disease causes a reaction in Swamp Bay trees, leaving them brown and dead. * How is our forest ecosystem doing??
19
* How is our forest ecosystem doing??
Round 2 A fungus, called the Laurel Wilt, is spreading through the Everglades and southern Florida. This tree disease is causes a reaction in Swamp Bay trees, leaving them brown and dead. A logging company came through the Tropical Hardwood forest in this area and cut all of the Live Oak Trees down * How is our forest ecosystem doing??

Round 3 A fungus, called the Laurel Wilt, is spreading through the Everglades and southern Florida. This tree disease is causes a reaction in Swamp Bay trees, leaving them brown and dead. A logging company came through the Tropical Hardwood forest in this area and cut all of the Live Oak Trees down * How is our forest ecosystem doing??
21
Our first CER! You are going to read 2 articles, one about deforestation and one about forest fires. Each article has 2 questions at the top that will help you figure out what information to look for in the article. Any time you come across information that answers the 2 questions, highlight/underline it. When you are finished reading the 2 articles and highlighting/underlining, you will complete the CER question on the third page. Let’s read the first two paragraphs of the deforestation as a class to get you started, then you will be working on your own. You will have 15 minutes after we read together; this is your Exit Quiz for the day (you may complete it for Homework if you need more time) There will be NO TALKING during the independent work time
22
Biology Pretest WHY…. An important check-in for yourself, your teacher and the school district WHAT… 30 minutes, multiple choice. ONLY WRITE ON THE BUBBLE SHEET; be sure that you circled the bubble with your name on it at the top There will be no talking Do your best but don’t stress... You got this!
