Water conservation
Where household water goes, what contamination looks like before a laboratory confirms it, and the specific things a community can observe and record. Includes what to do when a water source is upstream of something worrying.
In order, though nothing stops you starting where you need to.
The uses people think are large, and the ones that really are.
Colour, smell, foam, fish. And the limits of each.
Buffer zones, upstream uses, and who to talk to.
Four weeks of observations at one point. Evidence starts here.
Lesson content in preparation
The structure, sequencing, formats and assessment design are complete and shown here in full. The teaching material itself is written with teachers and reviewed against the DepEd curriculum before any school uses it.
