I took my 10 year old grand-daughter to the Perot Museum/Dallas during spring break. The building and attractions are new and beautiful. It is five stories of amazing exhibits and many wonderful interactive things for kids to do. I loved the dinosaurs and large turtle skeletons. Grand-daughter was amazed with the 35 foot petrified tree and various pertrified poop. The gem area is soooo fascinating - they had a 6-7 foot tall amethyst geo cut in half. The museum is usually sold out; purchase/print tickets on line. It was very crowded due to spring break. The museum assign a time for you to enter; I would like to return at a quieter time. The 30 minute 3-D movie (fee) on weather on other planets was new to us. I think pre-teen and teens would enjoy it.
