OBJECTIVE

By the end of the lesson, students will be able to:

  • Identify differences in drainage between sand, loam, and clay soils

  • Explain how soil type and pH affect plant growth

  • Match crops to the soil type in which they grow best

  • Amend soil to adjust pH toward a target range

  • Use runoff pH testing to evaluate whether soil conditions meet crop needs.

FUTURE READY

In this lesson, students take on the role of agronomists, using observation, data analysis, and problem-solving to improve soil conditions. They test soil, measure pH, and make adjustments—learning that real-world challenges require ongoing testing and improvement. This process builds systems thinking and shows how science informs decisions about food, resources, and the environment. Students also explore careers like agronomy, environmental science, and sustainability. Most importantly, they develop curiosity, persistence, and a mindset focused on solving real-world problems.
