CEE students used Legos, straws and leaves to inspire youngsters at the American Association for the Advancement of Science (AAAS) Family Science Days Feb. 16-17, part of the organization’s annual meeting held this year at the Hynes Convention Center in Boston. A book co-authored by Professor Penny Chisholm also played a role, winning the AAAS/Subaru SB&F Prize for Excellence in Science Books in the children’s science picture book category. 

Two exhibit booths were organized by juniors Tara Soni and Therese Santiano-McHatton, the former and current presidents of the MIT student chapter of the American Association of Civil Engineers. The booths offered interactive, educational demonstrations of photosynthesis (sponsored by Chisholm’s lab) and the properties of materials at different scales (sponsored by Professor Markus Buehler’s Laboratory for Atomistic and Molecular Mechanics). 

Chisholm’s book, Ocean Sunlight: How Tiny Plants Feed the Seas (Blue Sky Press, 2012), which was co-authored and illustrated by Molly Bang, was displayed at these booths as well. 

Professor Jesse Kroll's research group in atmospheric chemistry staffed a booth (in collaboration with Kathleen Vandiver and the MIT Center for Environmental Health Science) that taught visitors to use Lego bricks to model the composition and relative quantity of molecules in air, and the complete and incomplete combustion of a hydrocarbon fuel. The goal of these activities was to teach participants the origin of air pollutants such as carbon dioxide, carbon monoxide and particulate matter. Kroll's group also demonstrated sensors they use in their research to detect particulate matter in the atmosphere. 

“We had about 200 people visit the Lego air pollution booth, including 100 participants age six to 14, who filled out surveys highlighting the cool new things they learned about air and air pollution,” said postdoctoral associate Eben Cross, who co-led the exhibit with Van
