OLOGY, the kids' website of the American Museum of National History, provides students with resources and related activities on a variety of topics, including anthropology, archaeology, astronomy, biodiversity, the brain, climate change, the earth, Einstein, expeditions, genetics, marine biology, paleontology, water, and zoology. Kids simply click a topic to go to its main page.
Each topic page provides a scrolling information bar called "Did You Know?" Topics may include a variety of interesting facts -- for example, "A black hole with the mass of the Earth would be about the size of a marble" or "Light has no weight and no mass." There also is a variety of games, activities, and informational texts about scientists who work in each field as well as links to museum exhibits on each topic. Kids can collect and save cards anytime they see a red asterisk on the site. Once they've accumulated enough, they can use the card images to create a digital story and compete to get into the Ology Hall of Fame.
