Stuart Flack, a policy researcher and senior fellow at the Environmental Law and Policy Center, collaborated with the Wisconsin Science Festival to pilot this project. 

Featured Festival

While LEGO are widely used in museums and schools for sculpture, building, robotics, and all sorts of creative play, our project, “What Color is ______?” at the 2018 Wisconsin Science Festival, marks the first time that LEGO has been used to conduct a large-scale survey and to store and visualize the findings in real time.

Over two summer pilot tests and four days in October, more than 2,000 children visiting UW Madison’s Discovery Building participated avidly in our project. We asked them to answer 21 questions about themselves and the world using only 2×4 multi-colored LEGO blocks in 12 colors.
