Science Museum

The CosmoCaixa, aka the Science Museum in Barcelona is run by La Caixa (a Bank) Community Projects. It's purpose is to stimulate knowledge and people's opinions of science through exhibitions and a wide variety of activities. Located near Tibidabo atop the city, some highlights of the exhibit include the Flooded Forest, which recreates 1000 m2 of an Amazonian rainforest ecosystem and features piranhas, crocodiles and other animals and plant species typical to the zone. There is also the Geological Wall which is made up of seven sections of real rock which illustrate the world's various geological structures. It's a great day trip, or half day, especially with kids.
