Happy 250th! Our museum will be OPEN 10am–7pm on July 3 and 10am–5pm on July 4.

Join our museum’s Gallery Guides for a “drop-in” tour that explores the vital impacts made by engaged communities on scientific discovery, environmental justice, and public health.

Our Science & Activism Tour invites visitors to consider these questions: Who is a scientist? Who is an activist? How does each bring about change?

Stories include the influential book Silent Spring by conservationist Rachel Carson and the rise of the environmental movement; ACT UP, the AIDS crisis, and the development of the patients’ bill of rights; the Black Panthers’ lead role in community testing for sickle cell anemia; and the community-led research conducted by neighborhood coalition groups fighting to make government and industry accountable for environmental injustice.

This tour offers a broad picture of the ways activists have reshaped our understanding of science and how visitors can become engaged today through community science.


Drop-in tours are free and no reservations are necessary.
