This lesson introduces students to the concept of soil not just as dirt but as a vital natural resource composed of mineral particles, organic matter, water, and air. Students will learn about the three main types of soil—sandy, silt, and clay soil focusing on their unique properties such as texture, water retention, drainage, and nutrient content. Through detailed comparisons and examples, students will understand how different soils support various plants and ecosystems. The lesson also highlights the importance of soil in supporting plant growth, filtering water, and providing a home for many organisms. Engaging activities like the soil jar test and planting seeds in different soils help students explore soil composition hands-on, reinforcing the learning with practical experience.
