3 best natural disaster working model science project ideas for exhibition howtofunda

soil erosion science working project, in this course teaches students about one of the most important environmental challenges—soil erosion—and how it affects agriculture, ecosystems, and human life. The course explains the scientific causes of soil erosion, such as wind, water flow, deforestation, and overgrazing, while also highlighting its negative effects like loss of fertile land, reduced crop yields, and environmental degradation. Through step-by-step instructions, learners create a working model that demonstrates how soil erosion occurs on slopes or flat land when exposed to rainfall or flowing water. Students also experiment with preventive measures such as planting vegetation, building barriers, or using cover crops to reduce erosion. By engaging in hands-on activities, learners develop a clear understanding of the importance of soil conservation and sustainable land use. This course is ideal for school projects, science exhibitions, and competitions, combining theory with practical learning to inspire awareness and responsibility towards protecting natural resources. howtofunda
