Erosion in a Bottle (lab)
Source:
Water Action Volunteers
Activity (PDF)
In this activity, students study erosion
and its effect on the environment. Groups build a model that
demonstrates runoff and erosion, which can occur in both urban
and agricultural settings. After the students complete the lab
and look at other groups' results, you can discuss erosion
control practices. This can be adapted for an agriculture
education course by looking at the Natural Resource Conservation
Service (NRCS) requirements for residue as it relates to soil
loss and farming practices. Students receive a soil, they
determine texture by feel, and their group selects a crop
residue to apply to the soil. Groups choose 0%, 10%, 30%, and
60%. The NRCS has visuals the students can use as a reference.
The students then look at the amount of water run-off with each
residue. |
