The expansive preschool exhibit experience Engineers On a Roll comes to the Da Vinci Science Center in 2017. This new permanent visitor experience is a combined engineering lab, playscape, and climbing space that offers preschool children hours of active fun while they explore technology, mathematics, and engineering. Its colorful balls encourage kids to direct, sort, and experiment while the balls remain in constant motion. Long tracks that dip and curve show physics in real-time action.
