Ecosystems | Lesson 5 - Ecosystems Applications and Unit Posttest

Overview

Students learn about how humans depend on ecosystem products and services to survive and how we manage ecosystems to provide products and services that we want, as well as how increasing one product or service can decrease others. They develop posters about different ecosystems and complete the unit posttest.

Guiding Question

How do humans change ecosystems to provide products and services that we need?

Activities in this Lesson

  • Activity 5.1: Introduction to Ecosystem Products and Services (40 minutes)
  • Activity 5.2: Ecosystem Products and Services Jigsaw (50 minutes)
  • Activity 5.3a or 5.3b: Ecosystem Posters (40 minutes)
  • Activity 5.4: Ecosystems Unit Posttest (20 minutes)

Lesson 5- Ecosystems Services and Posttest (students as explainers)

Activity 5.1: Introduction to Ecosystem Products and Services

Students explain how humans change matter cycling and energy flow in ecosystems to produce products and services.

Activity 5.2: Ecosystem Products and Services Jigsaw

Students explain how humans manage matter cycling and energy flow in specific ecosystems to produce products that they need (beef, corn, forest).

Activity 5.3a: Ecosystem Posters

OR

Activity 5.3b: Ecosystem Posters

Students use posters to explain matter cycling, energy flow, and ecosystem services in a different ecosystem.

Students use posters to explain matter cycling, energy flow, ecosystem services, and effects of disturbances in a different ecosystem.

Activity 5.4: Ecosystems Unit Posttest

Students show their end-of unit proficiencies for the overall unit goal: Questioning, investigating, and explaining how carbon cycles and energy flows in ecosystems.

NGSS Performance Expectations

High School

  • Interdependent Relationships in Ecosystems. HS-LS2-2. Use mathematical representations to support and revise explanations based on evidence about factors affecting biodiversity and populations in ecosystems at different scales.
  • Matter and Energy in Organisms and Ecosystems. HS-LS2-5: Develop a model to illustrate the role of photosynthesis and cellular respiration in the cycling of carbon among the biosphere, atmosphere, hydrosphere, and geosphere.

 

Middle School

  • Matter and Energy in Organisms and Ecosystems. MS-LS2-4. Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
  • Earth’s Systems. MS-ESS2-1. Develop a model to describe the cycling of earth’s materials and the flow of energy that drives this process.
Three-dimensional Learning Progression

In Lesson 5, students consider several real-world situations to apply their understanding of ecosystems and carbon cycling. Thinking about real-world situations will help students apply their knowledge and understand the relevance of this topic.
