About Us

Shocking experiments, bottle rockets, whale bones! GCSW makes hands-on science exciting, and brings it to communities in the South County.

iMission and History

Since 2011, the Greenfield Community Science Workshop (CSW) has been a dynamic part of the City of Greenfield’s educational and recreational efforts. Created to provide accessible, hands-on science experiences for all, the CSW fosters curiosity, creativity, and confidence in young learners. Located centrally in Greenfield, the workshop is within walking distance for most families and serves as a trusted hub for science exploration.

Our mission is to serve as South Monterey County’s leading science education resource center. We welcome students, teachers, families, and community members to engage with the physical and natural world through meaningful, hands-on learning opportunities. With deep ties to the community and a team of dedicated lifelong learners, the Greenfield CSW helps ignite a love for science that lasts a lifetime.

What We Do

Greenfield CSW offers a variety of engaging science programs designed to meet the needs and interests of diverse learners:

Tinker Time Drop-In Program

A free, open-ended science space where children and families explore projects of their choosing in a safe, inclusive, and culturally welcoming environment. With over 250 sessions each year, Tinker Time supports over 7,500 individual science experiences.

Through partnerships with local school districts, we provide classroom visits, science kits, and field trips that reach more than 20,000 students annually in Greenfield and Soledad.

ScienceMobile (Ciencia Ambulante)

Our traveling museum brings interactive exhibits to schools across South Monterey County, delivering more than 6,400 hands-on science experiences each year to towns like Chualar, Gonzales, Soledad, King City, and more.

Greenfield Bike Garage

Offering free repairs for bikes, skateboards, and scooters, the Bike Garage hosts weekly sessions and large-scale events in seven towns, restoring over 660 items in the past year alone.

Our Impact

Greenfield CSW makes science tangible and fun for thousands of individuals each year. By creating hands-on, culturally responsive science experiences, we empower youth to become active learners and confident problem-solvers. Our inclusive, free, and accessible programming ensures that every child—regardless of background—has the opportunity to engage with science in meaningful ways.

Over the past year alone, we delivered:

7,500+ Tinker Time experiences
20,000+ school enrichment interactions
6,480+ ScienceMobile learning experiences
660+ bike restorations

We’re not just teaching science—we’re building a community of explorers, creators, and future innovators across South Monterey County.
