MODULE 3 CORE Lesson: Soil Science & Soil Health.

Описание: CORE LESSON - Soil Science 101: Why Healthy Soil is Key to a Sustainable Planet (Module 3)
What is the most important component of a sustainable food system? The answer is soil! This video dives into Module 3: Soil Science & Soil Health, providing high school students with the foundational knowledge to understand the critical role healthy soil plays in our planet's future. Learn how soil properties affect plant growth, water quality, nutrient cycling, and the essential carbon cycle.

We connect theory to hands-on practice, showing why understanding the ground beneath our feet is crucial for combating climate change and ensuring global food security.

Key Concepts and Hands-On Activities Covered:

== Soil Health & Ecosystem Services: Discover the vital role of soil microbes and learn how healthy soil provides essential services like water filtration and carbon storage.

== Soil pH Activity: Learn how to test soil samples for acidity or alkalinity and discuss how pH levels directly influence a plant's ability to absorb vital nutrients.

== Soil Organic Matter (SOM) Analysis: Use soil color as an indicator of Organic Matter. See how high SOM supports water retention and nutrient cycling.

== Soil Structure & Respiration: Witness soil aggregation ("soil glue") and test for microbial activity by observing the release of CO₂ (respiration).

This lesson reveals how farming practices can either deplete or restore ecosystems. Watch to see soil in action!
