TEKS 3.10B: Formation of Soils
Soil
About this lesson
Learning Target: I can explain how soil is made from broken-down rocks and old plants/animals, and describe how different soils (sandy, silty, clayey) feel and hold water based on their tiny pieces!
Focuses On:
- How soil is formed through weathering and decomposition, and the components.
- How different types of soil are formed, their particle size, and water retentions
Builds On:
1.10A:
investigate and document the properties of particle size, shape, texture, and color and the components of different types of soils such as topsoil, clay, and sand
Next Level:
Students will not focus on soil alone again at higher levels.

This lesson is designed to support students' understanding of how soil is formed through the processes of weathering and decomposition, and how these processes result in different soil types with distinct properties.
The lesson begins with an introduction to the components of soil and the formation processes of weathering and decomposition. It then explains the different properties of sand, silt, clay, and loam, linking these properties back to how each soil type was formed.
This lesson builds on students' understanding of soil from standard 1.10A, in which they explored different soils and were introduced to basic soil terminology.
