Waterbear Field School

At Waterbear Field School, we build useful things outdoors, together.

Field Days

All welcome. Field Days are open build sessions and skill-shares 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.

Solar Power & Electronics Bench

Lincoln Park, Somerville

Learn the basics of electricity by hooking up small solar panels, lights, batteries, and motors, and measuring voltage, current, and resistance with a multimeter.

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.

Building Bike Trailers

Artisans Asylum, Allston

Learn how to build a cargo trailer for a bicycle from two ten-foot lengths of half-inch electrical conduit, a pair of recycled 16″ children's bike wheels, four laser-cut steel dropouts and a handful of bolts — about $40 of parts, and it carries real loads.

Learn how to build a cargo trailer for a bicycle from two ten-foot lengths of half-inch electrical conduit, a pair of recycled 16″ children's bike wheels, four laser-cut steel dropouts and a handful of bolts — about $40 of parts, and it carries real loads.

We start with the one real skill in it: bending conduit, which is easy once someone shows you and unforgiving if nobody does. Then we drill, bolt and square up the frame, mount the wheels on the dropouts, and fit the hitch — a short length of braided vinyl tubing and a standard Burley hitch that clamps to the rear axle.

Note: for this workshop, we'll be building one bike trailer design together, and donating the bike trailer to the city. If you like the design, you can make arrangements with us at the workshop to purchase the materials to build your own.

Cold Frames & Winter Growing

Umbrello Hay Field, Lincoln, MA

Build a cold frame and keep growing food through the cold months — the simplest season-extending structure there is, and one you can reproduce at home.

A cold frame is a box with a clear lid, and it is the cheapest way to push a growing season weeks further at both ends. We look at how they work, what makes a good one, and why the old designs settled where they did.

We design first, then build — working through the details so the result is something you can copy at home without a plan from us.

More details ▾Fewer details ▴

A bike trailer is the cheapest cargo capacity there is, and you can make one in a morning. Ours uses two ten‑foot lengths of half‑inch electrical conduit, a pair of recycled 16″ children's bicycle wheels, four laser‑cut steel dropouts, and a handful of bolts — about $40 all in.

You'll learn to bend conduit, which is the one real skill in it, and then drill, bolt and hitch the frame together. The design comes from Edge Collective and the Somerville Bike Kitchen, and the files are open — so you can make another one, or a bigger one, after you go home.

A bench is the first tool. Without one you are holding the work with your knee; with one, everything else becomes possible. And a bench that folds is a bench you can take to the job instead of carrying the job to it.

Waterbear Field School

About

Waterbear Field School is a hands-on, outdoors skill-share for kids and adults.

What are Field Days?

Field Days are hands-on, outdoors, screen-free skill-shares for adults and kids 6+. Every day is a different mix of skills and topics — from woodworking and fiber arts to plant walks, hikes, and farm salons. Every day has a pay-what-you-can registration, no questions asked — registering also reserves your materials and tells us how many to expect. See what’s coming up on the schedule. You can also read about recent Field Day and Field School projects in the Journal, or find out more about our philosophy and approach in the Philosophy & Structure section.

Philosophy & Structure

A few things to know before you join us for a Field Day.

Let’s Go 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. 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.

Structure

Waterbear Field School operates as a recreational and enrichment program, not a licensed school or daycare. We don’t offer ‘drop off’ — children under 14 must be accompanied by an adult caregiver.
