Yesterday I taught maps to P6, particularly how to add text markers and network with each other. The mesh doesn't do what I'd expect, so I only got a few of the students networked. But those who did - they totally got it.
Today was water quality. I had the whole World Water Monitoring Day kit (pH, dissolved oxygen, turbidity), plus hundreds of litmus papers. We tested everything. All of the students had fetched water from boreholes - except maybe one or two had wells. I wrote everything down, so that I can GPS and photograph more of these sources later.
If we could measure water hardness/softness, I could have demo'd the problem that Moses clued me into, the problem with the Kigarama borehole. That thing is definitely rusting out. Fortunately, it and the Kigarama school were on my map photos. But very disappointing to see people getting water from that hole, when a shallow well a hundred feet away is pumping out clean water.
Matthew, who's been helping out me and a Harvard student filmmaker, recommended I chek out Rweteera school, which is a few miles down the road (actually a bit more than a few). Their rain barrels "don't work" and the kids wash in the river. Want more information on this. Tomorrow is a soccer game for all the schools, so I'm going to make a day trip down there.
