Today in Science provides an enlivening daily peek into the history of the scientific enterprise. Each day, ScienceNetLinks, a project of the American Association for the Advancement of Science (AAAS), publishes a two-paragraph gloss of an important event in the history of science. For instance, November 24th corresponds to the day that Charles Darwin published his earth-shaking treatise, On the Origin of Species, in 1859. After perusing the short description of this monumental event, users may then link to a host of resources from ScienceNetLinks, such as collections about Darwin, a section about what we can learn from fossils, a comparison of the competing evolutionary theories of Lamarck and Darwin, a page dedicated to the evolution of feathers, and a game based on the theory of natural selection. Rather than limiting users to a particular day in history, a handy calendar feature lets users select any date of interest. With 365 entries to choose from, educators are sure to find inspiring material for classroom discussions, daily trivia, or a variety of other educational activities.
