Powerhouse Science Center

Sacramento Science Discovery Weekends

Welcome to the Discovery Museum

Science & Space Center


Our mission statement:

€œPowerhouse Science Center is a dynamic regional hub that engages and inspires people of all ages to explore the wonders, possibilities, and responsibilities of science.

Organization History: The Discovery Museum Science & Space Center has operated for 60 years as a 501(C)(3) nonprofit agency. Our tax ID is #68-0321106. Originally founded in 1951 as the California Junior Museum, the Center was designed as a space where children could experience science and nature through interactive programs and exhibits. Today, the Discovery Museum is one of Northern California's premier institutions with an emphasis on STEM (science, technology, engineering, math) education and hands-on learning.

Looking Toward the Future: Over the next few years, the Discovery Museum will transition to a new facility: the historic PG&E power station on the Sacramento River. The new facility will be known as the Powerhouse Science Center.
