Do One Act of Science for America’s 250th—Right Here in Philadelphia
Do Acts of Science
In 2026, join thousands of Philadelphians celebrating our nation’s 250th birthday by taking part in simple Acts of Science that protect wildlife, explore our night sky, and strengthen our city.
Throughout April 2026—Citizen Science Month—and the 2026 migration season, you can:
Philadelphia was the birthplace of America. In 2026, it becomes the birthplace of 2.50 million Acts of Science.
Join in. Make a difference. Celebrate together.
Projects
Explore the Night Sky Across Philadelphia
In April 2026, volunteers from The Franklin Institute, NASA’s Night Sky Network, Dark Sky Network, Globe at Night, and Lights Out Philly will host stargazing stations throughout the city. Philadelphians can look through telescopes or binoculars, learn to identify constellations, and help measure light pollution.
