Frequently Asked questions

Is there a cost?

No, the Chelsea Science Festival is a free event.

Is the Festival Handicap Accessible?

 Yes, the Chelsea Science Festival doesn't want anybody to be left behind so every year we have this fun, free event at PORT Park in Chelsea, MA. 

Is the Festival accessible from public transportation?

Yes, the closest MBTA bus stop is the blue line 116/117 stopping at Marginal Street before crossing the Andrew McArdle Memorial bridge on the Chelsea side going into East Boston or the first stop in Chelsea after crossing the bridge if commuting from Boston. The Silverline is a couple minutes away in walking distance stopping at the Airport Parking Garage in Chelsea. The green line/orange line 111 is in a longer walking distance but still feasible. 

WHO & WHY we started the Chelsea Science festival?

The Lewis Latimer Society & Museum for the past 20 years has been offering programs in STEM. The society was concerned since the city was changing, that the people who were going to be left out or behind were the kids. So we started working with after school programs and summer learning programs and going on field trips that promoted STEM. Overall, we wanted to organize and get other groups in the community into STEM and offer more STEM activities in the city of Chelsea such as the Chelsea Science Festival which is also designed to support teachers.

What are we looking for in the future?

  • Keeping the Chelsea Science Festival expanding each year and gaining popularity to get more organizations involved in the City of Chelsea
  • Bringing in different organizations to come into the community and make connections with the people and other organizations to work together in the future
  • Increasing the number of collaborators/ partners/ volunteers/ sponsors each year
