12-3pm
Join Keystone Kidspace’s own Mr. Matt and the Master Watershed Stewards for a day of creekside adventures at Codorus Creek (located right in our backyard)!
Included with Open Play admission, you’ll help create a collaborative art installation on the Patio, launch sailboats, try fly fishing, collect aquatic insects for examination, skip rocks, and see what other scientific discoveries lie just beneath the surface.
If you’re planning to embrace the splashy side of science, please bring tall rain boots or a change of clothes (open toed shoes will not be allowed in the creek, including Crocs).
No paddle required—we’re Up Kid’s Creek!
