Good report.

Your educational stuff reminded me of something my father did with us everywhere, when we went to a beach on the ocean. He would pick a time early in the week to show us the power of the water. I can remember standing in ankle or knee deep water, getting our feet buried and then being moved by the water down the beach. He had us observe where we were, then about 15-30 minutes later, we looked up and were at least 10 yards down the beach. His message was always to be respectful of the water and not in fear of it. Respect for it keeps you out of situations when you should be in fear.

When you go back, the stuff you taught last time can eb gone over, and you can also expand. Teach a little more, even one thing, each time, and you will end up with children who will know quite a lot. Moreover, the chidlren you teach will not be abel to help themselves. They will teach other children. And lessons learned this way are not easily forgotten.

Nice.
