July 16–August 6, 2017

For several weeks each summer, Brookhaven Lab welcomes members of the public to its site. We plan days that include visits to our facilities, opportunities to speak with our researchers, special activities for adults and children, and much more—and it’s all free!

Summer Sundays 2017 has ended. Information about next year’s Summer Sundays will be available in spring 2018.



Family Fun Day

A fabulous day of hands-on family fun with the Science Learning Center! Come enjoy the thrill of exploration in the Science Learning Center where all the exhibits are designed for school-aged children. Have fun with the fundamentals of science with hands-on activities about engineering, electricity, sound, light and more! We are also celebrating 70 years of Discovery and a Century of Service this year. Photos and memorabilia about our history will be on display in Berkner Hall Lobby – including artifacts from Camp Upton, the US Army camp established here 100 years ago in 1917. And for visitors interested in the history of Camp Upton and Brookhaven National Lab, we are planning special history talks and a historical bus tour of the BNL site. View daily schedule



Exploring the Ultra Small

Tour the Center for Functional Nanomaterials, where Brookhaven scientists study structures as tiny as a billionth of a meter. Discover the weird and wonderful things that happen at the tiniest of sizes with hands on activities about the nanoscale. Bring the kids and come see our Center for Functional Nanomaterials where scientists are working to understand and improve materials for energy. Scheduled science talks, “Energy, CO2, Climate, and You!” by Dr. Stephen Schwartz  and “Your Smart Phone through the Eyes of a Nanoscientist”  by Dr. Mark Hybersten. View daily schedule



Brilliant Light, Dazzling Discoveries

Visit the National Synchrotron Light Source II, where scientists use intense beams of light to see the inner structure of batteries, proteins, space dust, and more. Come find out what it means to be a “photon microscope” and why we are so excited about this incredible machine. View daily schedule.



Atom-Smashing Fun*

Explore the Relativistic Heavy Ion Collider, where particles are smashed together at near-light-speed to reveal the secrets of our universe. Visit our particle collider, where physicists study what the universe may have looked like in the first few moments after its birth. View daily schedule

* Facility tour appropriate for ages 10 and over.
