Discover STEM in 30

Join us for STEM in 30, an interactive classroom program consisting of 30-minute webcasts that engage middle school students in STEM topics ranging from WWI airplanes to rovers on Mars. Chat with experts, submit your questions to be answered live, take a poll, discover related content, and participate in follow-up activities.

Our format has changed!

To better reach your classrooms and facilitate conversations with your students, we are updating the way our show is released.

Here’s how it works:

  • We release an episode on the second Thursday of each month.
  • You can watch it on-demand as your class schedule allows.
  • We host a live video chat with Beth, Marty, and experts from the episode the third Thursday of each month.*
  • You bring the burning questions that came up when you watched the episode and dive even deeper on each month’s topic

*Exact date of live chat subject to change. 

Watch STEM in 30 on this page or on NASA TV. You can also view archived programs on-demand. Learn more about STEM in 30.
