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:
- Description of the ecosystem or environmental issue
- Causes of the problem
- Effects on organisms and the environment
- Examples or evidence from reliable sources
- Possible solutions
- 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.
Evaluation
| Criteria | Excellent (4) | Good (3) | Fair (2) | Needs Improvement (1) |
|---|---|---|---|---|
| Content Accuracy | Information is accurate, complete, and clearly explained. | Information is mostly accurate and clear. | Some information is incomplete or unclear. | Information contains several errors. |
| Research | Uses several reliable sources and provides strong evidence. | Uses reliable sources with adequate evidence. | Uses limited sources or evidence. | Uses very few or unreliable sources. |
| Analysis | Clearly explains causes, effects, and possible solutions. | Explains most causes, effects, and solutions. | Explanation is somewhat incomplete. | Shows little understanding of the issue. |
| Creativity and Organization | Output is highly organized, creative, and easy to understand. | Output is organized and understandable. | Output has some organizational problems. | Output is difficult to follow. |
| Presentation | Presents confidently and clearly and responds well to questions. | Presents clearly with minor difficulties. | Presentation needs more preparation. | Has difficulty explaining the output. |
Total: 20 points
Conclusion
Through this WebQuest, you explored how ecosystems are connected and how human activities can affect the environment. You also learned how to search for reliable information, analyze environmental problems, work with others, and propose possible solutions.
As a final reflection, answer these questions:
- What did you learn about the relationship between humans and ecosystems?
- Which environmental problem concerns you the most, and why?
- What is one action you can personally take to help protect the environment?
Remember that protecting the environment is not only the responsibility of scientists and government organizations. Small actions by individuals and communities can also contribute to a healthier ecosystem.

WebQuest Title
Exploring Ecosystems and Human Impact
Subject Area
Science / Biology
Intended Learners
Grade 8–10 students
Time Required
Approximately 2–3 class periods
Overview
This WebQuest is designed to help students understand the relationship between organisms, ecosystems, and human activities. Through guided online research, students will investigate an environmental issue, identify its causes and effects, and develop possible solutions.
The activity uses an inquiry-based approach where students take the role of environmental researchers. They will gather information from reliable online sources, analyze what they discover, work collaboratively, and communicate their findings through an infographic or presentation.
Learning Objectives
At the end of the WebQuest, students should be able to:
- Identify major environmental issues that affect ecosystems.
- Explain how human activities can affect organisms and their environment.
- Analyze the causes and effects of a selected environmental problem.
- Evaluate information from reliable online sources.
- Propose practical solutions to help address an environmental issue.
- Communicate their findings through an infographic or oral presentation.
- Demonstrate responsible attitudes toward environmental protection.
Curriculum Connection
This WebQuest supports science learning related to ecosystems, biodiversity, environmental issues, human impacts, and environmental conservation. It also develops 21st-century skills such as critical thinking, collaboration, communication, research, digital literacy, and problem-solving.
Teacher Preparation
Before starting the WebQuest, the teacher should:
- Introduce the basic concepts of ecosystems and human impact.
- Explain the purpose and procedures of the WebQuest.
- Organize students into individual or small-group teams.
- Provide access to computers, tablets, or smartphones with Internet connection.
- Check that students can access the recommended online resources.
- Remind students to use reliable sources and properly acknowledge information.
- Prepare the assessment rubric before the activity.
Teacher's Role
The teacher will act as a facilitator and guide rather than simply providing information. The teacher should monitor students' progress, ask guiding questions, help students evaluate online information, and provide feedback when necessary.
The teacher may ask questions such as:
- What evidence supports your findings?
- How does this environmental problem affect the ecosystem?
- Which human activities contribute to the problem?
- Are your sources reliable?
- Which solution is realistic for your community?
Student's Role
Students will act as environmental researchers. They are expected to:
- Conduct online research.
- Work responsibly with their group members.
- Evaluate information from different sources.
- Record and organize important information.
- Create their assigned output.
- Present their findings to the class.
- Reflect on what they learned and how they can help protect the environment.
Assessment
Students will be assessed using the WebQuest rubric based on:
- Content accuracy
- Quality of research
- Analysis of causes and effects
- Proposed solutions
- Creativity and organization
- Presentation skills
The total score is 20 points.
Differentiation
To support learners with different abilities, the teacher may:
- Provide a list of recommended websites for students who need additional guidance.
- Allow students to work individually or in small groups.
- Provide graphic organizers for students who need help organizing information.
- Allow students to present their work through an infographic, slideshow, or oral presentation.
- Provide additional time when necessary.
- Pair students who need assistance with classmates who can provide peer support.
