Here’s something for the K-12 educators out there (or just those who like to play around with large chunks of wood. I mean, who doesn’t?). I just posted a new episode for my Science Teaching Tips podcast. Check out the new episode – “Take it from the Top”. Don Rathjen was a K-12 science teacher for about 20 years, and then started working at the Exploratorium to bring great science activities to teachers. (I’ll give you more of his activities later, which include a working pendulum clock and a ticker-tape time… all marvelously clever contraptions. He has more patience than I do!). This one is an Exploratorium classic about center of gravity, an adaptation of an exhibit on our museum floor. Don seems to make a stack of blocks defy gravity in this one!
