Slough News: Discover The Slough At Night

One of the most popular activities at the Mercer Slough Environmental Education Center in Bellevue is back for another season. Slough Sleep-Ins are an overnight adventure for students in grades 1 through 4. Play games, venture out on a night hike and conduct a series of experiments in our lab. Sleep over in one of our brand new classrooms and then explore the Slough by day during a search for birds and animals. Wrap up your Mercer Slough experience by using nets and our video microscope to discover the creatures that live underwater. →Learn More
