Visitors will engage in a variety of survey type questions focusing on different aspects of nanotechnology. For each question posed, they will be provided short descriptions about the possible options. They will then place their vote using a marble in the container labeled with their selection. Throughout the day the public will be able to visualize how others have answered the same question by looking at the quantity of marbles in each container. Museum staff can use the data to chart trends in public knowledge about nanotechnology.
