    LEARNING OUTCOMES

    Students conduct experiments to study the properties of different soils, to find ways to prevent their degradation. They also study their biodiversity and the role of this biodiversity.

    They learn that:

    • Soil health is a major concern since it supports human settlements (buildings, agriculture, roads, etc.).

    • Soil contains a rich biodiversity which contributes to food production, through agriculture.

    • Some human activities may lead to soil degradation, such as fertiliser and pesticide use, overcultivation or deforestation. Inherent biodiversity of soil can reduce the need for fertilisers and pesticides.

    • Erosion may represent a threat for soil stability, and thus for human activities. It may be reduced if grasses grow on the soil.
