This is LOADED with places to visit online for free.
Aquariums, Museums (Anne Frank's House....we just spoke about her before school was out) , The Great Wall of China, Zoos from all over the world!
Go to the Louvre and see The Mona Lisa! Go to Egypt and see the Great Pyramids! Go to the Field Museum in Chicago and see the Arachnid Collection.
The choices are plenty and all worth a visit.
