A total lunar eclipse will be visible in North America on February 20th beginning at 8:43 pm Eastern and 5:43 pm Pacific time. This prime-time celestial show should be an excellent teaching opportunity for young astronomers, and several good web resources are available. NASA’s Eclipse Home Page is the most extensive, with downloads that include […]

The new Polar Sciences Collection from Teachers’ Domain includes 20 new resources, lesson plans, and student activities funded by NSF as an education activity of the International Polar Year. Teachers’ Domain has also catalogued other resources already on the site that complement the Polar Collection. Nearly all the new resources are available in the Open […]

The team that made the popular eSkeletons project has launched eLucy, a new site that supports Lucy’s American tour. “Lucy” is a partial skeleton of a 3.2 million-year-old Australopithecus afarensis. Evolutionary biologists consider the bones among the most important clues to the origins of the human race. Lucy almost certainly walked upright and […]
