Upcoming Field Days

All welcome. Field Days run 10 AM to 1 PM, for adults and kids 6+ (an adult caregiver needs to accompany kids under 14). Registration covers materials and keeps the day running — and if the cost would keep you away, every day has a pay-what-you-can registration, no questions asked.

We start from the very beginning — what a volt is, what a battery actually does — and build up, part by part, hooking up small solar panels, lights, batteries, and motors.

Along the way you'll get comfortable with a multimeter, measuring voltage, current, and resistance for yourself. Nothing is a black box: by the end you'll understand every wire.

Philosophy & Resources

A few things to know before you join us for a Field Day — plus guides and resources to explore and build on your own.

Let’s Be Outside

Field Days are outdoor programs, and we’ll be outside in all but extreme conditions. We keep an eye on the forecast, choose sheltered spots when we can, and take breaks as needed — but the best thing you can do is come dressed for the weather. Layers, sturdy closed-toe shoes, rain gear, sun protection, and a water bottle go a long way. We’ll always let you know if a day calls for anything special.

Safety

Every Field Day follows established safety procedures, and our facilitators are trained in them. We review expectations with participants at the start of each day, keep group sizes manageable, and make sure the tools and activities are appropriate for the ages taking part. We don’t offer ‘drop off’ — children under 14 must be accompanied by an adult caregiver, who shares responsibility for their child’s safety and participation.

Waivers

All participants (or a parent/guardian, for minors) complete a waiver form before their first Field Day. We’ll share the form ahead of time so you can fill it out in advance and we can get started without paperwork on the day.

Resources

  • Zines & guides — free, hand-made booklets on the basic science and engineering behind resilience skills (solar, water, heating, and more). Read online or print your own.

More guides and zines coming soon.

Questions about any of this? Email us — we’re happy to talk it through.

What are Field Days?

Field Days are hands-on, outdoors, screen-free skill-shares for adults and kids 6+, running 10 AM to 1 PM. Every day is a different mix of skills and topics — from woodworking and fiber arts to plant walks, hikes, and farm salons. Everything’s free — just show up. See what’s coming up on the schedule. You can also read about recent Field Day and Field School projects in the Field Notes, or find out more about our philosophy and approach in the Philosophy & Resources section.
