On a warm weekend in October 2021, about two dozen OLLI members and an equal number of Berkeley undergraduates gathered for an intergenerational design challenge. This informal STEM learning experience is the capstone event of the National Science Foundation research study awarded to us and two campus partners, The Fung Fellowship and the Lawrence Hall of Science, in the fall of 2019. The students were an amazing group of go-getters (smart, empathetic, engaged) and, no surprise, so were the OLLI members!
