  • Can Plants Stop Soil Erosion? This article from Science News Explores discusses the potential of plants to reduce soil erosion. Soil erosion can have negative impacts on farmland, waterways, and can even contribute to landslides. The article suggests conducting a mini experiment to investigate whether plant roots, which absorb water and hold onto soil, can help reduce erosion. The experiment involves planting radish seeds in pans of soil, exposing the soil to rainfall, and comparing the amount of soil eroded with and without plants. The full activity and instructions can be found at snexplores.org/erosion in partnership with Science Buddies.
