North Bay Science Discovery Day

Ever wished there was someone who could answer all of the obscure questions your kids throws at you? North Bay Science Discovery Day will create that sort of all-knowing atmosphere. More than 100 exhibitors will partake in this free, volunteer-created STEM event (science, technology, engineering and mathematics), each with a specific question to answer. Visitors will learn about STEM subjects through a number of unique and creative activities, making the day a little less science class and a little more summer camp.
