The lessons in this unit provide methods for students to carry out three investigations to ask questions about differences in the land cover types for three important dimensions of the schoolyard ecosystem:
- the biological community – earthworms
- the physical environment – percolation of water into soil
- the social dimension – people’s use of the schoolyard
The unit culminates in a final lesson where students have the opportunity to pursue topics they identify themselves. This can be set up simply as an open inquiry opportunity, or as a way of pursuing specific whole-schoolyard questions that might have surfaced during previous inquiries.
