I received a brochure from these guys in the mail. There classes look quite interesting. Here's the pitch:
"This mobile unit hits the road daily to bring hands-on science activities to children and life-long learners throughout New Mexico -- it's the field trip that comes to you! Book a visit to your club, childcare center, or summer camp today."
This sounds like something we might be able to do as a group, if anyone would like to organize it. They have many 90-minute classes for ages 5 and up, cost is $100 for up to 25 kids, so it could be pretty cheap! There's one class listed for ages 9 and up that's more expensive, $250.
