Understanding Soil Properties and Textures

Miss Villa's science class continues with a focus on soil. The lesson covers the importance of soil for plant growth and animal habitats, the benefits of soil, and the different types of soil, including sand, silt, and clay. The properties of these soil types, such as water retention and grain size, are discussed. Additionally, the lesson touches on the various colors and textures of soil, using examples like the saffron-colored earth in Mauritius. The class concludes with an invitation for questions in the next meeting.
