Science & Technology

There’s a renewed interest in, and urgent need for, Science, Technology, Engineering, Mathematics (STEM) literacy today. Portland Public Library strives to engage the community with a  fascination for science, the wonders of the natural world, and the possibilities of technology. Through explorations of all kinds – information services, hands-on learning, digital experiences, and public programming – the Science & Technology team aims to stimulate understanding, exploration, and creativity with the sciences and present the fun, the useful, and the very interesting.

Be a Citizen Scientist

Doing science can be fun! You may think of research as teams of professional scientists at work but with the aid of the Internet, non-specialists can contribute, too.  As “Citizen Scientists” we can share in scientific data collection and providing access to scientific information within our communities.  PPL promotes citizen science through events, educational programs, and volunteer opportunities for you to explore science or technology on your own, increase personal understanding and appreciation, and contribute to the research underway.

AZA Frogwatch USAVisit our partner, Cornerstones of Science, for upcoming citizen science opportunities including FrogWatchUSA.

Science research affects us and the world we live in every day. We may think it happens in remote labs but, in fact, great science is being done in our own backyard.  Come meet a scientist. In the informal setting of the library’s atrium,  USM faculty will share what they’re up to. Coffee and cookies provided.

Climate Change

Our lives are integrally connected to the climate.  Learn more at the library about how human societies have adapted to the relatively stable climate we have experienced since the last ice age and the changes, anticipated or unanticipated, that a warming climate will bring.  How we react, how we adapt, how we protect our environment, our health, and our safety, depends on understanding and a will to action.
