Grades K-5. Drop in. Pick up a hands-on activity kit that lets kids explore Science, Technology, Engineering, and Math right at home! This month's kit gives you the opportunity to build your very own robot to light up the room! Our popular DIY kits are available starting on the first of each month, while supplies last. Kits are first-come, first-served. Limit one per child; no multiples for classrooms or daycares, please.
