Teachers (those of you in the South who start before labor day…), get your eclipse-explainer hat on! This is your chance to finally help your kids understand the Earth–moon-sun relationship. You’ll never have them this motivated to understand it again. NASA has a huge collection of materials–you can access all of them from this launch page.
The whole site is worth messing around with, but I’ll call out the k-12 lesson plans and the resources for informal science venues (libraries, museums, etc.) . But I’m also loving their section on MATH INTEGRATION–a series of math challenges from elementary level through high school/ undergraduate that also help students understand the eclipse.
