The Innovation Institute in Newtonville will hold two open houses — December 5 (6:30PM-8PM) and December 8 (2:30PM-5PM) to introduce winter-term classes in science and engineering for ages 5-15. In this after-school/weekend program, scientists and education specialists work with up to ten students in a class to offer learning and inspiration designed to complement day-school studies. Classes are two hours, once a week. Topics range from the neuroscience of the senses to the science of renewable energies, with a focus on fun learning, critical thinking skills, freedom to create and innovate, and mastery of STEM concepts.
