Math is Power
The Cambridge STEAM Initiative partners with the Cambridge Public Schools’ Math Department on initiatives that focus on math as a civil right. As part of this collaboration, the STEAM Initiative has hosted screenings of Counted Out, a documentary exploring how inequitable access to math literacy impacts us.

Open Our Doors Automatic Door Openers on Public Buildings
Many city buildings have heavy doors without automatic openers, often making access to these buildings a challenge. Touchless automatic door openers benefit those who are elderly, pregnant, using wheelchairs or walkers, pushing strollers, concerned about germs, or anyone who has their hands full.
CPL Nature Club: Rethinking Urban Green Spaces: Nature Walk with Earthwise Aware (Main)
Join Earthwise Aware (EwA) for an interactive walk to observe, document, and take part in shaping urban spaces that work with nature. Together, we will explore how design choices and climate pressures shape the ecological value of our everyday green spaces, and document habitat conditions using simple citizen science tools.
Starting at the library lawn, we will examine spaces that appear green but often function poorly. Manicured lawns and sparse tree plantings may look inviting, yet they frequently support little biodiversity and can limit soil health and resilience. What makes a space truly nature-friendly? We will record what is present, what is missing, and what that tells us about ecological function.
During the walk, we will:
Observe and document plant communities and habitat quality
Identify signs of low and high ecological function
Compare conventional landscapes with more resilient plantings such as native beds or meadow patches
Contribute real data that supports local ecological understanding and decision making
This is participatory science in practice. Your observations will feed into broader efforts to track urban biodiversity and inform better land use choices.
The program will meet outside the library in Joan Lorentz Park. Registration required.
Rain date: Wednesday May 6
