Welcome!

LexCAN is a Lexington-local climate action and advocacy group. We work with partners and collaborators for meaningful change. Join our movement!

The Give Grass a Chance Campaign was Successful!

Thinking Globally, Working Locally

Through a variety of interactive & educational programs organized to help our community work through the most urgent and necessary changes.

Helping Residents Electrify Everything

LexCAN works closely with the Town of Lexington's sustainability team to create programs like Clean Heat Lexington.

Reducing Waste and Protecting Ecosystems

We work closely with many local partners like LexZeroWaste, Lexington Living Landscapes, and many more organizations for maximum impact.

Advocating for Policy Change

LexCAN has helped turn climate ideas into town bylaws — including the nation’s first gas-powered leaf blower ban and a law banning fossil fuels in new home construction. Advocacy isn’t just talk.

Have fun, explore, and learn outdoors and inside at Discovery Museum’s free Nature Play Festival! We will gather with our community and local businesses to offer immersive nature-based activities throughout our campus including Invasive Plant Papermaking, Mud Kitchen, Bug Hunts, Log and Rock Flipping, and so much more.

Explore our inclusive, accessible, and giant Treehouse and Discovery Woods nature playscape, and take a guided Nature Walk on the conservation land that abuts our campus. The fun will continue indoors with our STEM-based galleries and hands-on activities.

Sensory accommodations will include a Take-a-Break tent, an ASL interpreter onsite 11:30am to 3:00pm, and ASL yoga in the early afternoon. As always, we will have noise-reducing headphones available to borrow in the lobby.

There will be food, music, and fun as we connect with nature and appreciate the wonderful planet we all call home.  Free admission for all.  Rain or shine.
