Importance of ground cover
Class: 6ème, 4ème
Lesson: Les plantes et l'homme: leur importance dans le monde vivant Erosion
Rationale: Show that ground cover slows down erosion.
Materials:
2 sugar boxes
candles
matches
clump of grass with soil
soil
3 glasses
water
Procedure:
1. Poke holes in the short side of two sugar boxes.
2. Seal the insides of the boxes with melted candle wax to make a filter.
3. Fill one filter with a clump of grass and soil and the other with loose soil.
4. Incline the two filters.
5. Add a glass of water to both filters and collect the filtrate.
6. Compare the quantity of water and soil in each filtrate.
