Sparking creativity and igniting innovation in young minds.

A preschool exploration program with a STEAM focus!

Young explorers will immerse themselves in nature and outdoor play (rain or shine!), as well as hands-on learning in science, technology, engineering, art, and math. Children will be guided by master teachers and special guest educators including naturalists, artists, scientists, and more!

Our distinctive challenge-based curriculum ignites an interest in the “big ideas” of science and critical and creative thinking. Our lessons are aligned with the Next Generation Science Standards.

See your child “glow” at Little Sparks!

Girls do STEAM

This program is meant to reach elementary-school aged girls, who are forming their own identities now, as they explore and learn about their own possibilities within the world of STEAM. 52% of women working in the areas of STEAM site an educational experience that took place in elementary school as setting their path. In order to ensure that girls are getting those experiences, we offer workshops that showcase women as mentors and teach them the skills they need. Since aptitude is not gender based, we focus on building the girls confidence, which is the most important factor in their involvement in the areas of STEAM moving forward.


Schools & Groups

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.


Science, Engineering and Innovation Camps

We bring our expertise and innovation to your location. Our educators develop a series of workshops and activities. We customize to your needs. Students always leave asking for more! These STEM camps are highly popular during school breaks and for energizing students during the year.

In House Field Trips

Hands-on Workshops for Young Scientists, Grades Pre-K to 6TH!

Fabulously FUN hands-on investigations explore Science, Technology, Engineering, Art, Math, all while including a literacy component.

Our new Career and Civic workshops incorporate career awareness and civic engagement with hands-on learning. Our in-house workshops are 2 hrs long, which includes a 90 min workshop and a 30 min exploration time. Extended hours can be arranged where needed.

In School Field Trips

We have developed a program that allows us to take the Explorium on the road. Our in-school and after school workshops focus on bringing smart and fun workshops that challenge elementary aged children to think for themselves as they work to develop their own solutions to the open-ended challenges we pose for them. Every field trip is led by a certified instructor and is accompanied by take-home materials.

Here are a list of our workshops.

Teachers & 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.

Educate the Educators

“Educate the Educators” program will provide comprehensive teacher professional development workshops to low income school districts located on Long Island. This program is designed to empower teachers to embrace a challenge based approach to STEM education and to lead STEM workshops in their classrooms. The workshops are aligned with the New York State Science Learning Standards and are designed to foster creativity and critical thinking skills among the students. The project is designed to support turnkey training of colleagues thereby creating a lasting impact and establishing a professional learning community within the participating districts.
