The fourth Wellesley STEM Expo — free and open to the public — will be held on April 6, 10AM-3PM, at Wellesley High School (50 Rice Street). Last time, over 3000 attended this amazing event (see the video recap of the 2017 Expo). From 10AM to 2PM, there will be over 100 exhibits, 14 workshops (workshop space is limited), and a showcase of student work. A featured exhibit will be Picturing Science, adapted from the exhibit at the American Museum of Natural History. At 2PM, this year’s keynote speaker — Dr. Cheryl Knott, Professor of Anthropology and Biology at Boston University — will speak about her work to protect the wild orangutans of Borneo. At 3PM, there will be a Meet-a-STEM-Professional networking reception. Register for free. Check out opportunities to be a sponsor.
