On selected evenings during February, March & April, Family STEM Nights were held at CMMC. Families of students in the Monomoy school district were encouraged and challenged in creativity, critical thinking and perseverance, all while having fun.
Cheri Armstrong, the librarian at the Elementary School in Chatham and one of the educators involved with our Verizon Foundation project, proposed a series of "Family STEM Nights." The results exceeded our expectations as the first series of nights was overbooked, and we extended the series to include a second topic.

After many months of meetings and negotiations with the Town of Chatham and the Building Department, the approvals from the Planning Board, Historical Commission and the Zoning Board of Appeals, a Building Permit was issued and the lease for the "Hotel" was signed on February 27th, and renovations began.
The building is commonly referred to as Hotel Nautilus from its days used by the RCA staff and the Navy in WWII. The first floor will be converted into expanded exhibit space, education center, meeting space, archival space and administrative space.
