Exploring Ecosystems and Human Impact

Introduction

Have you ever wondered what would happen if one part of an ecosystem suddenly disappeared? Plants, animals, microorganisms, water, air, and humans are all connected in different ways. Changes in one part of an ecosystem can affect the entire environment.

In this WebQuest, you will become an environmental researcher. You will explore reliable online resources to learn how ecosystems work and investigate how human activities affect them. Your goal is to understand an environmental problem and suggest ways people can help protect the ecosystem.

Task

Your task is to investigate one environmental issue that affects an ecosystem. Examples include:

  • Deforestation
  • Water pollution
  • Plastic pollution
  • Habitat destruction
  • Climate change
  • Overfishing

You will create an Environmental Awareness Presentation or Infographic that includes:

  1. Description of the ecosystem or environmental issue
  2. Causes of the problem
  3. Effects on organisms and the environment
  4. Examples or evidence from reliable sources
  5. Possible solutions
  6. Actions that students and communities can take

 

Process

Step 1: Choose an Environmental Issue

Choose one environmental issue from the list provided by your teacher. Work individually or with a small group.

Step 2: Research

Use the online resources provided by your teacher to answer these questions:

  • What is the environmental problem?
  • What causes it?
  • Which organisms or ecosystems are affected?
  • What are its short-term and long-term effects?
  • What can people do to reduce the problem?

Take notes and record the sources of your information.

Step 3: Analyze the Information

Discuss your findings with your group members. Identify the most important causes and effects of the environmental issue.

Create a simple cause-and-effect diagram showing how human activities can affect the ecosystem.

Step 4: Create Your Output

Create an infographic or presentation that summarizes your research. Make sure that the information is accurate, understandable, and supported by reliable sources.

Step 5: Present Your Work

Present your output to the class. Explain the environmental problem, its effects, and your proposed solutions.

After the presentation, listen to the ideas of other groups and compare the different environmental issues.
