MoMath Exhibits Coming to the Explorium for a Limited Time

Jan. 26th - The Long Island Explorium in Port Jefferson is proud to present two engaging MoMath exhibits: “Ring of Fire” and “Miles of Tiles,” in partnership with the National Museum of Mathematics.  The Exhibits are part of the "MoMath 2 Go: The Family Math Initiative" which aims to help families with children in preschool through second-grade become more comfortable talking about math. The partnership is sponsored by the Heising-Simons Foundation, which works to support sustainability, clean energy, human rights and the education young children.

In "Ring of Fire," children can touch the clear 3D shapes to make laser lights appear.  The ring of eye-safe laser light is invisible - until a visitor places a solid object in its path.  Then beautiful and surprising cross sections instantly appear: hexagons in a cube, parabolas in a cone, or contour maps on the surface of a hand.

“Miles of Tiles” allows kids to create with brightly colored magnetic shapes that can be combined in limitless ways to create a panorama of patterns and tessellations.

Additionally, the exhibit includes MoMath 2 Go “tip cards” that provide talking points for parents to communicate mathematics to their children more effectively.

Last day of exhibition - March 24th, 2019.

Eastern Long Island Mini Maker Faire 2019

We’re gearing up for our 2019 Mini Maker Faire! We’re looking for Makers to showcase their creations and Volunteers to make the event a success.

The future belongs to the CURIOUS. The ones who are not afraid to TRY it, EXPLORE it, POKE at it, QUESTION it, and TURN it inside out. 


Constructivist Approach

Children are not empty vessels to be filled with knowledge by teachers; but rather continually constructing their own knowledge. Constructivist teaching invites learners to consider socially important, relevant challenges and endeavors.

Fail Forward

Failure is not a bad thing. It helps us to develop ‘GRIT’. Grit is a distinct combination of passion, resilience, determination, and focus that allows a person to maintain the discipline and optimism to persevere in their goals even in the face of discomfort, rejection, and a lack of visible progress for years, or even decades.

Play to Learn

Through play children can learn to make sense of the world around them. Play helps children to develop social and cognitive skills, mature emotionally, and gain the self-confidence required to engage in new experiences and environments.


For Families and Children: 

Our curriculum, exhibits and educational approach are unique by design, developed to spark inventive solutions, build confidence by embracing the “fail forward” concept and foster teamwork through hands-on workshops and activities that pose challenges with multiple outcomes or solutions. Because of this focus on creativity and innovation, the Explorium is recognized as Long Island’s Family Maker Space, a place for families to play, create, build and grow together.

For Students: 

Our workshops are smart and fun! We nurture children’s thinking as they work to develop their own solutions to open-ended challenges. STEM workshops include evidence-based writing, career awareness, and civic engagement components. Our distinctive challenge-based programs are built on New York State Science Learning Standards, New York State English Language Arts and Mathermatics Learning Standards, and the National Core Arts Standards.

For Educators: 

The Maritime Explorium is a New York State certified provider of Continuing Teacher and Leader Education ( CTLE) credits. Our programs help inspire teachers to incorporate STEAM and constructivist approaches into their standards-based lessons. Teachers learn how to foster engagement of all learners through hands-on challenges that explore the engineering design process, encourage teamwork, and incorporate career and civic awareness.
