Quote of the day: “This is the best science class I’ve had — ever!”  150 6th graders explored CaveSim today at Falcon Middle School.  They’re studying rocks and the rock cycle, and they learned all about speleogenesis (how caves form).  They also learned about cave rescue, and some even saw a TP-6N field telephone, used for in-cave communication during rescues (see http://fieldphone.blogspot.com/).  A big thanks to Jeff Polk for putting these phones on long-term loan.  Also, a big thanks to Margaret Browne (Falcon Middle School science teacher) for inviting us, and for helping so much during the day (helping with gear, providing lunch and helping to maintain order!)
