Have I mentioned that I really love Oak Meadow? The enrichment activities are so great. Take our lesson on Bernoulli's Principle and the Principles of Flight, for example. We had a textbook lesson that explained Bernoulli's Principle and its relation to flight, and then OM had Thing 3 experimenting with paper airplanes to gain a concrete understanding. He told me today that it was one of the best days he's had this year. But then, who doesn't love playing with paper airplanes?
