TOWNSEND — Squannacook Elementary School teachers Christopher Barnacoat and Shelley Babin are gearing up for the After-school Enrichment Program by teaching their students to construct a geodesic dome.

According to Barnacoat, the dome will be constructed out of PVC pipes and will take approximately six weeks to complete.

“A geodesic dome is the strongest and lightest structure (with) the most volume,” he said. “It is a series of triangles that turn into pentagons and hexagons when it is all put together.”

The students will begin by making their models out of plastic straws and paper clips so they can see how the dome will fit together. Barnacoat made a diagram out of cut paper to give the students some direction.

Barnacoat said he saw the geodesic dome during a field trip to Nature’s Classroom in Freedom, N.H., and decided it would be a good project for his students.

“It will be a good project for them to work on,” he said. “The program runs every Tuesday after school until Nov. 28.”

Geodesic domes are used for housing as well as storing scientific equipment.

“Not too far away from here there is a geodesic dome that houses a very large telescope,” he said. “It’s an amazing structure.”

Last year, Barnacoat constructed a sun dial which sits in the Squannacook garden.
