Get Involved

Interested in joining How On Earth’s production team? We’d be glad to have you!

Our volunteers come from diverse backgrounds including journalism, science, engineering, and more. What unites us is a passion for exploring and communicating scientific topics over the airwaves, and a love of independent community radio.

Students are especially welcome, and for-credit internships can be arranged.

Contributing to How On Earth can be a great way to gain experience in:

  • Writing for radio
  • Recording interviews and producing sound-rich features
  • Hosting live broadcasts and conducting on-air interviews
  • Running (“engineering”) a sound board during a live broadcast
  • Posting content to the show’s website and social media accounts
  • Communicating science in accessible, listener-friendly ways

We welcome new volunteers at all levels of experience. A good first step is to attend one of KGNU’s station-wide Volunteer Orientations. Then send an email to the How On Earth production team to find out how you can help: contact [no spam] (just put the @ where it belongs).
