Yesterday was the first day of school. We got up and had breakfast. After the breakfast I remembered that Nat had been persistently asking about a patch of lichen we pass every few days, and I had been saying vaguely, "It's lichen. I think it's like moss?", so we looked it up in the Nature Encyclopedia, stopping at protozoa on the way (fascinating. Single celled organisms that are neither plant or animal. Many are fierce predators. Nat defined predator for me, very clearly). Lichen, it turns out, is a symbiotic mesh of fungi and algae that doesn't need soil and never flowers.
We pointed out lichen patches on our way to the farmer's market.
After the market the boys went to my parents' for the afternoon, and I came home with the girls. I had a nap and then organized and purged in a frenzy of activity,while Geoff continued the shelves in the basement. When the boys got home I got Nat to sound ouf five or six words in a storybook we were reading, watched the Phineas and Ferb about the Gordian Knot, and called the day an educational win.
Dunno what we'll do today...
