MORE FREE: Are you planning a visit to Philadelphia this summer? There are several free and educational sites to drag your kids to — they’ll have fun, grudgingly.

The Wagner Free Institute of Science is a unique natural history museum with exhibits on fossils, animals from around the world, and the evolution of the scientific field since the museum’s inception 170 years ago. The institute is also known for its long-running, and also free, adult education programming.

U.S. Mint in Philadelphia gives free tours. Visitors can see the production of coins and learn about the history of the Mint.

About 90 minutes from Philadephia is the Allentown Art Museum in the Lehigh Valley. The permanent collection is diverse, from European paintings to contemporary American installations. Etchings, photography, textiles, Tiffany glass and accessories — there is so much to see.

Independence National Historical Park contains two of Philly’s most popular historic attractions: the Liberty Bell and Independence Hall. Go to the Old City to see where the U.S. Constitution and the Declaration of Independence were signed. You can explore Independence Hall on your own, but tickets are required for guided tours—but you’ll pay just $1 online.

Philly’s Science History Institute preserves and promotes understanding of the history of science — “Bugs and Bakelite buttons. Lab notes and lifesaving letters. Vaccines and vats of bright, colorful dyes. Our digital and in-person exhibitions explore the diverse and surprising histories behind the science that shapes our world.”

The National Museum of American Jewish History is a Smithsonian-affiliated museum in Philadelphia. “It offers a comprehensive insight into the American Jewish history, making it a worthwhile visit for those interested in cultural and historical explorations.”
