Check out this list of 50 different Virtual Field Trips from MomsLA.com.
"The great part about digital field trips is they’re accessible to everyone. No need to take a long road trip or deal with the stress of an airport to marvel at the wonders spread across our nation’s 50 States. Every state has thousands of wonderful places to visit, of course, but in the interest of time and space, we’ve chosen just one iconic and magical spot per state – and anyone can “visit” anytime since they’re all virtual."
