Founded by Robert Powrie Harland, Sr.,[3] Discovery World was initially known as the Science, Economics and Technology Center.

With the push of a button, visitors can call for "rain" to fall down upon this watershed, observing where the water flows and how run-off pollutants navigate the region.

Tank exhibits replicate a wide variety of aquatic habitats, including that of Lake Michigan, the Pacific and Atlantic Oceans, the Caribbean Sea, and much more.

The Dream Machine allows the public to design products to take home, experience a custom-built automated factory, and learn modern engineering trends.

Visitors can operate the controls of the retractable domes of Miller Park and the Milwaukee Art Museum.
