Highlights for High School
Curious about black holes and distant galaxies? We encourage you to check out this incredibly rich course from the Chandra Astrophysics Institute (CAI). The CAI is an opportunity for students in grades 9 -11 to come to MIT to train for and undertake astronomy projects.
This course is organized around six different investigation topics and features extensive notes, dozens of hours of video, and an image gallery.
Special note to teachers: The investigation notes were created with you in mind! They contain details about how to set up each activity, assessment ideas, and special tips and tricks.

Views from Supporters
"I completely agree with your iconoclastic view that all online knowledge should be free.

However, whenever we do not have enough students for a given class to be taught by our own faculty member, I asked our few students to look for an appropriate class on OCW."
