Attendees from across the country descended on the nation’s capital to speak up for science.

The March for Science unfolded on the National Mall in Washington, D.C., on Saturday, and in multiple cities around the world. Coinciding with Earth Day, the event drew researchers, educators and scientifically-minded people.

The event kicked off with open teaching sessions on the Mall, followed by a rally near the Washington Monument, and then a march that traveled to the U.S. Capitol building.

NPR spoke to some of the participants about why they decided to attend the March for Science.
