When is a good time to study the Sun? How about March 18-22 during Solar Week? Teachers can find good resources for solar studies throughout the year at the Solar Week site and the Sun-Earth Day site, but during Solar Week, you have the opportunity to interact live with solar scientists by submitting questions. (There’s another Solar Week in October, in case March doesn’t work out for you.)
Sun-Earth Day happens on or around the Spring Equinox. The 2013 theme is “Solar Max–Storm Warning!” exploring the violent nature of our Sun at the peak of solar activity and sharing discoveries that come from NASA’s heliophysics missions. You can find lesson plans divided by grade on the Sun-Earth Day “Get Involved” page.
