Did second tour only, starting in Pyramid/Ascending Dragon room. Students enjoyed analyzing the pyramid picture and talked about the different views – arrived at the extraterrestrial theme themselves. Cool. Talked about the polygraph experiment and art piece. In substrate room, the sketch on the wall with the long fuse and tiny person was a hit; close looking rewarded. One student thought the explosion looked like a toasted marshmallow.
Hercules was recognized from the art session upstairs. Nice to see in real size. Canvas on Moon inspired good discussion (2nd graders!). Mandala a thought-provoking hit. In the first section, our last stop, only had time to pass by the window shade piece (new substrate!), which they liked, and briefly the colored Gunpowder Study in the first section.
Would like to try the dragon story somewhere. Didn’t have time for more than one activity (substrate search); work on making more time for another. For me, second hour groups are more squirmy; thinking of doing something physical in the garden before going inside.
An amusing question: What’s the substrate of a peanut butter and jelly sandwich?

I think the question “what is the substrate of a pbj?” can be extended to any sandwich, excepting an open-faced sandwich. It is a great question for discussion.
