Who We Are

We strive to be a leader in STEM discovery, learning and innovation that will shape the intellect, social values and principles of future generations

We work to advance STEAM concepts that translate into skills to address social, economic and environmental issues.

We stay COMMITTED to supporting STEM LEARNING outside the classroom and in our COMMUNITY through our VIRTUAL ONLINE Programs during this time


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.

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. 


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 Long Island 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.
