The Science History Institute joins the Delaware River Festival for its 7th annual celebration of the mighty Delaware.

This annual event brings people together on the Philadelphia and Camden waterfronts for a day of family-friendly fun, educational activities, and water-centered learning. The Delaware River Festival offers something for the whole family: free ferry rides, museum visits, pedal boats, face painting, a scavenger hunt, crafts, and so much more!

Learn about three environmental problems humans have caused or worsened in the world’s oceans, some of the tools and techniques scientists use to monitor these issues, and ways in which the general public can take action. And make your own plankton with paper plates and crayons!

This event is free and open to the public, and no tickets are required.
