Besides being an enormous human tragedy, the sinking of the Titanic is a fascinating scientific and technological study. Visitors to Titanic Science, on display at the Science Museum of Virginia, in Richmond (800-659-1727; www.smv.org ), from October 5 through January 4, can try to steer a simulation of the liner out of harm’s way, feel how cold an iceberg is, pilot a model of one of the robot vehicles that are used to salvage artifacts from the wreck, and see an IMAX film about the sinking. For stay-at-homes, www.titanicscience.com has a wealth of technical information about the Titanic and its brief life, with an activity guide for students and teachers.
