On Thursday mornings, Seacoast Science Center hosts its Big Fish Little Fish Play Day, a drop-in play and exploration time for children ages 1-5 with an adult. Educator-designed activity stations are set up around the Center to engage children in fine and gross motor skills, sensory, literacy, math and creative activities. Pop-up story times and outdoor mini-adventures may be offered based on weather and the theme of the day. Reservations are recommended but not required to attend Big Fish Little Fish on Thursday mornings. This program is FREE for SSC members; regular admission applies for non-members ($10 adults, $8 seniors, $5 for children ages 3 and over).
