Join a Children's Museum Educator to learn about river ecosystems as we investigate models of structures made by some of nature's very best architects and engineers! From mammals to birds - participants will get to examine and hypothesize about these builders, think about how they work together, and explore models of the incredible structures they create, and complete a fun, hands-on activity!
