Science Museum Announces Free Becoming America Exhibition Exploring How Science Shaped the United States

Science Museum has announced a major new free exhibition, Becoming America: How Science Shaped a Nation, opening on 23 October 2026 to mark 250 years since the signing of the United States Declaration of Independence.

Running until 25 April 2027, the exhibition will explore how science, technology, and innovation helped shape the land, people, and identity of what became the United States during a pivotal period between the 1760s and 1790s.

Created with support from Library of Congress, the exhibition will feature more than 100 objects, including a rare surviving Dunlap print of the Declaration of Independence, a pioneering Gulf Stream map created by Benjamin Franklin and Timothy Folger, and scientific items linked to both King George III and George Washington.

Visitors will also discover stories often overlooked in traditional narratives, including the scientific knowledge of Indigenous communities such as the Haudenosaunee Confederacy and contributions from people of African descent, including astronomer Benjamin Banneker.

Among the standout displays will be a traditional Mashpee Wampanoag dugout canoe, a surveyor’s compass linked to the historic Mason–Dixon Line survey, and Charles Willson Peale’s famous mastodon excavation artwork.

According to Sir Ian Blatchford, the exhibition offers a fresh perspective on the origins of America by highlighting how science influenced politics, agriculture, exploration, and national identity.
