The Menlo Park Main Library will host a visit from the “Try-It Truck,” offering grade schoolers the opportunity to explore hands-on science learning stations, using tools and the engineering design process to solve challenges. The event is free, thanks to the Friends of the Menlo Park Library, and will take place from 2:00—4:00 p.m. outside the library at 800 Alma Street. For more information, visit menlopark.org/children.
