The 10 Best Free Stem And Building Clubs For Kids in Fairfax County
Fairfax County has more free STEM and building clubs for kids than anyone realises, scattered across venues and buried in calendars that are a chore to search. These are our picks — the ones that run on a schedule you can plan around, for school-age children. Each links to the official listing so you can confirm the details before you go.
These are the 10 most regular — the ones that run on a predictable schedule. 3 more occasional sessions run across the same branches; each library's calendar has the full list.
