Essential Question: What is an ecosystem?

Objective: SWBAT define an ecosystem

Materials:
Class Poster (KWL)
Sticky Notes
Science Journals

What is an Ecosystem

Activity Websites:
  1. What is an Ecosystem (KidCyber)
  2. Geography4Kids - Biosphere
  3. Earth Floor - Biomes
  4. Definition of an Ecosystem



Do Now: On a sticky note, students write down what they believe an ecosystem is. When finished, students will place their post it note on a large KWL chart under K

Mini Lesson: Take picture (ie: grasslands) and ask “what do you see? What is this? What about the ants, water, etc?” Start building a foundation for “ecosystem” definition. Then show the Ecosystem YouTube Video and have students take notes on “What is an Ecosystem?” After watching, list examples of Ecosystems that were mentioned in the video and other “not so traditional” ecosystems.

Activity: Students will work in groups to read and report on the content from one of five different websites about ecosystems. Students will be required to take notes in their science notebooks and share their finding with the classroom using a Google Doc set up to share results. After everyone has shared out, and students have added notes from all groups into their science journal, the class will develop a working definition of “ECOSYSTEM”

Project Task: What is an Ecosystem? Handout

Assessment:
  1. Classwork - Google Doc and Classroom Discussion
  2. Concept - Can students explain what an Ecosystem is in their Science Journal
  3. Homework - Completion of "What is an Ecosystem" handout

Standards:

MST Learning Standards
Standard 4—Science - Intermediate
3. Individual organisms and species change over time.
5. Organisms maintain a dynamic equilibrium that sustains life.
7. Human decisions and activities have had a profound impact on the physical and living environment.

Standard 5 – Technology - Intermediate
2. Technological tools, materials, and other resources should be selected on the basis of safety, cost, availability, appropriateness, and environmental impact; technological processes change energy, information, and material resources into more useful forms.
3. Computers, as tools for design, modeling, information processing, communication, and system control, have greatly increased human productivity and knowledge.
5. Technology has been the driving force in the evolution of society from an agricultural to an industrial to an information base.
Students:


NYS - The Living Environment Core Curriculum
Grades 5-8

General Skills
4. recognize and analyze patterns and trends
5. classify objects according to an established scheme and a student-generated scheme
7. sequence events
8. identify cause-and-effect relationships
9. use indicators and interpret results

Living Environment Skills
6. classify living things according to a student-generated scheme and an established scheme
9. identify structure and function relationships in organisms

Key Idea 3:
Individual organisms and species change over time.
3.1b Changes in environmental conditions can affect the survival of individual organisms with a particular trait. Small differences between parents and offspring can accumulate in successive generations so that descendants are very different from their ancestors. Individual organisms with certain traits are more likely to survive and have offspring than individuals without those traits.
3.2a In all environments, organisms with similar needs may compete with one another for resources.

Key Idea 7:
Human decisions and activities have had a profound impact on the physical and living environment.
7.1a A population consists of all individuals of a species that are found together at a given place and time. Populations living in one place form a community. The community and the physical factors with which it interacts compose an ecosystem.
7.1c In all environments, organisms interact with one another in many ways. Relationships among organisms may be competitive, harmful, or beneficial. Some species have adapted to be dependent upon each other with the result that neither could survive without the other.
7.1d Some microorganisms are essential to the survival of other living things.


Describe the effects of environmental changes on humans and other populations.
7.2a In ecosystems, balance is the result of interactions between community members and their environment.
