Why Give?

With your generous support, the Explorium can exponentially expand the reach of its innovative exhibits, cutting edge educational and professional development programs to the children of our community of all ages and abilities. The result: a profound advancement in advancing STEM learning and innovation leading to a future generation of scientists, innovators, thinkers and tinkerers. Since 2005, the Long Island Explorium has hosted more than 125,000 visitors to the museum and reached more than 2000 students annually through our STEM programs on Long Island and beyond.

What is the Campaign for 2020?

2020 is not just an election year but a year that we are "electing" to focus our efforts in reaching 2020 underserved children and youth all around Long Island and beyond. These are communities that otherwise would not have access to our programming.

Join us and help us raise $150,000 in support of the Explorium's Campaign for 2020.

Update: December 2nd, 2019 - We have raised $110K! Help us surpass our fundraising goal!

Girls in STEM

Access to strong STEAM (Science, Technology, Engineering, Arts, and Mathematics) education is not equitable across the socio-economic spectrum. The statistics are striking with only 45% of Latinos and 46% of Blacks scoring at the “basic” level or better on standardized math tests. 44% of low-income students reach this basic level, while a full 77% of average-income students do.

Research shows that schools with large numbers of racial and ethnic minorities, low-income students and English Language Learners are systematically under served.

Funds raised will allow us to provide high quality STEM programming, resources and tools in these communities as well as invest in the teachers’ professional development so that teachers will be able to independently utilize these tools in their classrooms throughout the school year in all areas of STEM education. These teachers will be better able to help promote their students’ career and college readiness.

Studies show a tight link between confidence and girls’ performance in the areas of science and math. Data show that girls around the world, and certainly in the US, lag behind boys in math and science, but it’s not due to aptitude. According to the OECD researchers, “Aptitude knows no gender.” Alas, confidence does. “The strong relationship among self-beliefs, gender and performance in mathematics and science hints that countries may be unable to develop a sufficient number of individuals with strong mathematics and science skills because of girls’ lack of confidence in their abilities.”

The result is that only 12% of women, in contrast to 39% of men, choose to major in a science field. This lack of women in science and engineering affects our economy due to lack of skilled candidates for the S.T.E.M. workforce.

Funds raised will help us reach underserved girls and provide opportunities for developing critical thinking and problem-solving skills that will lead to improved self-esteem, leadership, and confidence to pursue future studies and careers in STEM fields. Our STEM programs empower girls by enhancing self-perceptions of abilities in the areas of STEM.

For ALL Members

ASTC Travel Passport Program (PDF)

You must have the NEW membership card with the ASTC logo on it. (All existing members must exchange your current membership card for the new one. Please bring your old card to the Long Island Explorium and you will receive your new Membership card with logo)

BEFORE YOU GO - check that the museum that you are visiting is participating in the passport program. Check that is is more than 90 miles from the Explorium.
*This distance is measured “as the crow flies,” meaning that it is based on the
linear radius, not driving distance.

Online radius tools can be helpful when determining if a Passport venue is within a 90-mile radius of the Explorium.  Go to
This tool allows you to draw two circles in different colors.  Enter the address of the museum where you are a member first (or their home address, if the museum they wish to visit checks IDs).  Then, enter the address of the museum you wish to visit and create a new circle in a different color.
