We had another visitor. Pythagoras came and taught us about his life and teachings. Most of the stories we hear about Pythagoras are more legend than truth, but it is still fun to learn about him.
It is told, Pythagoras observed that when the blacksmith struck his anvil, different notes were produced according to the weight of the hammer. After this the kids were broken into 2 teams, boys v. girls, and given PVC pipe, rubber bands, string and a pipe cutter and told to make a xylophone. After several attempts the girl team decided on a human xylophone! They even roped Pythagoras into helping.
The next day we used legos to demonstrate the Pythagorean theorem.
