Our fast-paced webcast series engages middle school students in Science, Technology, Engineering, and Math (STEM) topics in just 30 minutes. We bring in Museum curators, astronauts, and experts in the field to connect classrooms with real-world, relevant content. Shows combine animations, interviews with experts, and unique locations to show students that science extends beyond the walls of their school.

The shows are interactive. Students respond to polls and submit questions that are answered online or during the live broadcast. Educators are provided with additional content and follow-up activities to extend the experience beyond the live webcast. Each show meets Next Generation Science Standards. See the full schedule.

How It Works

  • We release an episode on the first Thursday of each month.
  • You can watch it on-demand as your class schedule allows.
  • We host a live video chat with our hosts and experts from the episode the second 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.
