Introduction
Have you ever noticed muddy water flowing down a slope after heavy rain, or soil collecting near a road, river, or low area? These may be signs that soil is being moved from one place to another. Soil erosion is a natural process, but it can become a bigger problem when vegetation is removed or when land is used in ways that leave the soil exposed. Rainfall, wind, slope, vegetation, and land use can all affect how easily soil is eroded. In this WebQuest, you will work as a young community environment team. Your goal is to investigate a soil erosion problem, find out what may be causing it, understand its possible effects, and think of ways to help protect the area. Instead of simply collecting information, you will use the resources provided to examine evidence and decide which solutions would be practical for the community.
Task
Your group of three (3) members has been asked to investigate a soil erosion problem in a community setting.
You will prepare a Community Soil Conservation Action Plan that answers these questions:
- What is happening to the soil?
- What factors may be causing or increasing the erosion?
- How can soil erosion affect plants, animals, people, and the surrounding environment?
- What can the community do to reduce the problem?
At the end of the WebQuest, your group will create a one-page digital action plan containing your findings, evidence from your sources, and at least three practical measures that could help reduce soil erosion.
Your group will also give a short presentation explaining why you chose these measures.
Process
Follow these 9 steps with your group:
1. Choose or receive a community situation.
Your teacher will provide a case or picture of an area where soil erosion may be occurring, such as a sloping area near a farm, roadside, or waterway.
2. Learn about the problem.
Read the resources provided by your teacher to understand what soil erosion is and how soil can be moved by water or wind.
3. Look for possible causes.
Identify the conditions that may be contributing to the problem. Consider rainfall or runoff, slope, lack of vegetation, and human activities that may leave soil exposed.
4. Examine the effects.
Find out how soil erosion can affect the soil itself and the plants, animals, people, and waterways around the area.
5. Compare possible solutions.
Research ways of reducing soil erosion. Think about which solutions are realistic for the community you are studying.
6. Choose your recommendations.
As a group, select at least three measures that you believe could help reduce the problem. Be prepared to explain why each one could help.
7. Create your Community Soil Conservation Action Plan.
Your one-page output should include:
- the problem you identified;
- the possible causes;
- the effects of the erosion;
- your three recommended solutions; and
- a short explanation of why your recommendations could help.
8. Present your action plan.
Briefly explain your findings and recommendations to the class. Each member should have a role in the group presentation.
9. Reflect on your learning.
After the activity, answer these questions:
- What evidence helped your group identify the possible cause of the erosion?
- Which solution do you think would be most practical for the community, and why?
- What did you learn about the importance of protecting soil?
Note: Use the resources provided in the Credits section to gather information for your investigation.

Conclusion
In this WebQuest, you investigated how soil erosion can affect a community and looked beyond simply defining what erosion means. You examined possible causes and effects, used online resources to support your findings, and developed practical ways to help protect the soil. Soil is an important part of the environment, and protecting it is not only about preventing soil from being washed or blown away. It also means thinking about how our actions affect the land around us.
Self-Reflection:
What is one thing you learned about soil erosion that changed the way you look at the land around your community? What is one action that you think people can realistically do to help protect the soil?

Intended Learners: Grade 5 Science
Purpose:
This WebQuest is designed to help learners investigate soil erosion in a community setting. Students will examine its possible causes and effects, use selected online resources to support their findings, and suggest practical ways to help reduce soil erosion.
Learning Focus:
Students will learn how soil erosion occurs, what factors can contribute to it, how it can affect the environment and the community, and why protecting soil is important.
Teacher’s Role:
The teacher introduces the activity, explains the task and expected output, guides students in using the provided resources, and assists them when they need clarification. The teacher also monitors group participation and uses the scoring rubric to assess the final output and presentation.
Group Setup:
Students may work in small groups to discuss their findings, compare ideas, and develop their recommendations.
