This project models the impact of deforestation on soil erosion using simple materials to showcase how tree removal affects soil stability.
If trees are removed from an area, then soil erosion will increase due to lack of root structure stabilizing the soil.

Fill the plastic container with soil and plant small grass or plants.
Water the plants and allow them to establish for a few days.
Carefully remove the plants to simulate deforestation.
Water the soil again and observe any changes.
Record how much soil washes away after watering.
Repeat the experiment with and without plants for comparison.
Analyze the differences in soil erosion.
Compile results and draw conclusions.
Soil without plants will experience more erosion compared to soil with plants, demonstrating the protective role of vegetation against erosion.

Handle soil carefully to avoid spills, and wash hands afterward.
Create visual comparisons of the erosion results.
Explain the ecological significance of preventing soil erosion.
Use graphs to show the amount of soil lost.
Engage the audience with questions about their own experiences with deforestation.
Soil erosion can lead to loss of fertile land and negatively impact water quality.
Planting vegetation and using erosion control methods can help.
While some erosion can be natural, excessive erosion is harmful to ecosystems.
