The Long Island Explorium encourages visitors to explore and play together in our hands-on interactive maker space rich with science/ STEM based exhibits and activities. While our focus is children ages 2-12 and their caregivers, we welcome visitors of all ages. The Long Island Explorium was launched in 2004 as โ€œThe Childrenโ€™s Maritime Museum at Port Jeffersonโ€ (CMM) by a group of local residents seeking a family-friendly educational experience.

๐ŸŒŽ Shake it. Build it. Hear it. Feel it.

Have you explored our TWO newest hands-on exhibits yet?

โšก Discover Radical Resonance โ€” experiment with sound, motion, tuning forks and vibration while meeting electrical engineer Aisha Lawrey.

๐ŸŒŽ The Seismic Shake-Up โ€” build, shake and rebuild as you experiment with earthquakes and engineering alongside earthquake geologist Dr. Wendy Bohon.

These exciting new exhibits were awarded to the Long Island Explorium through the Association of Science and Technology Centers (ASTC) and the IF/THENยฎ Champions Network, an initiative of Lyda Hill Philanthropies. We're thrilled to bring even more opportunities for kids to experiment, explore, and see themselves in STEM through the stories of real women scientists and engineers.

Come experience them for yourself on your next visit! ๐Ÿ”Šใ€ฐ๏ธ๐Ÿ—๏ธ
