STEM Activity Clearinghouse

The STEM Activity Clearinghouse is an online library of hands-on STEM activities contributed and vetted by librarians, museum educators, and informal learning spaces. Users can filter projects by age range, topic, difficulty, and setting, making it easy to find a quick one-off experiment or a multi-day challenge. Families and educators appreciate that activities are designed for real-world use in libraries and clubs, often using inexpensive materials. It’s especially useful for upper-elementary through middle school STEM blocks and maker clubs. Some entries assume group settings, but many adapt well for home. Bookmarking a small set of favorites per unit and prepping materials ahead of time turns it into an open-and-go resource.
