Why Kids ♥ It

OMSI is the perfect place to have fun while learning! Kids can conduct their own chemical experiments, see what outer space looks like, study thousand-year-old fossils, launch water rockets and more — all while developing critical skills like problem solving, communication, and attention to detail.

Why Parents ♥ It

Your young learners can explore, observe and experiment through interactive hands-on activities, with no cleanup required! The bright and airy Theory Café overlooks the Willamette River and delivers oven-fired pizza, salads, and local craft beer and wine, making it easy to keep everyone fueled up for science learning.
