I was a chaperone on Erich's Field Trip to the
Academy of Natural Sciences (aka The Dinosaur Museum). The teacher arranged a number of fun activities - Fur, Feathers and Scales (we got to meet a fox, duck and a turtle), a Visit to Outside-In (we met a guineau pig and a legless lizard) and the Butterfly Pavillion.
Here's Erich's class:
