“Sustainapalooza” is coming back to Sci-Port for its second year. Program Coordinator Nancy Larned says it’s all about learning how to incorporate greener living practices into our daily lives. And it features lots of green-themed activities for all ages…like Recycled Paper Making, Enviroscape and Water Ambassadors. Larned says there will also be several community partners talking about things like green homes, solar power and recycling. The event runs from 11 a.m. to 4 p.m. Saturday — and you can get two-for-one admission all that day.
