Dinosaur Train
The Earthquake/Nursery Car
The EarthquakeMom takes the kids on a playdate with Tank Triceratops to the desert, where they meet a distant relative of Tank's, an early Ceratopsian named Penelope Protoceratops. The Conductor points out that Penelope lives in a part of the world that gets a lot of earthquakes, and sure enough, the kids experience their first quake with Penelope. Mom and the Conductor have prepared the kids with excellent advice about what to do in an earthquake, so everyone does fine.Educational ObjectivesProtoceratops belongs to one of the major groups of plant-eating dinosaurs, called ceratopsians, which also included Triceratops and Protoceratops. The surface of the earth is divided up into big chunks, called "plates," that move around, carrying the continents with them. So the world we see today is very different from the world the dinosaurs lived in.Nursery CarWhen the family rides the Dinosaur Train, they learn that a new car has been added - a Nursery Car, with dozens of eggs in little, padded nests, attended by their expectant moms and dads. The kids watch the eggs hatch, and try to guess which hatchling goes with which dinosaur parent.Educational Objectives Aftershocks are small earthquakes that occur following a major earthquake. They happen when the Earth's crust adjusts to the effects of the main shock. Even giant dinosaurs hatched from relatively small eggs, but egg size is limited by restrictions on shell thickness. The shell must be thin enough to allow air to pass through tiny holes in the shell called "pores."
