Other organizations at this address

1 other organization in the IRS Business Master File lists the same street address. matched by us

We match the street line and ZIP code as the IRS gives them, ignoring case and outer spaces and nothing else, so "AVE" and "AVENUE" count as different streets and this list can miss some. A shared address can mean related organizations or a shared office, but it can also be a registered agent, a mail drop or a service provider holding mail for unrelated clients. It is not, by itself, evidence that two organizations are connected.

Mission

WE ENRICH PEOPLE'S LIVES BY REVEALING THE WONDER AND RELEVANCE OF SCIENCE.

Activities or mission (Part I)

IT IS OUR MISSION TO REVEAL THE WONDER AND RELEVANCE OF SCIENCE. WE DO THIS THROUGH INTERACTIVE EXHIBITS AND HANDS-ON EXPERIMENTS THAT FOLLOW AN INQUIRY-BASED LEARNING MODEL WHICH ENCOURAGES SELF-DISCOVERY AND CREATIVE, ORGANIC THOUGHT. BEING BOTH A SMALL MARKET PHYSICAL SCIENCE INSTITUTION AND A SMITHSONIAN AFFILIATE GIVES US THE RESOURCES TO MARRY TRADITIONAL SCIENCE EXHIBITS WITH ONE-OF-A-KIND ARTIFACTS THAT GIVE A CULTURAL CONTEXT TO THE SCIENCE EXPLORED IN THE MUSEUM.

  • SCIENCE EDUCATION:EDUCATIONAL PROGRAMS AND ACTIVITIES ARE PROVIDED FOR THE GENERAL PUBLIC AND SCHOOL GROUPS ON AN ONGOING BASIS THROUGHOUT THE YEAR BOTH IN THE MUSEUM AND THROUGH SPECIAL OUTREACH PROGRAMS. STUDENTS AND VISITORS CAN EXPERIENCE ONE OF OUR LIVE MULTI-MEDIA, AUDIENCE PARTICIPATION THEATER SHOWS, OR LEARN THE SCIENCE OF SPECIFIC EXHIBITS FROM ONE OF OUR MANY VOLUNTEERS AND FLOOR FACILITATORS. THESE ACTIVITIES SERVE TO PROMOTE INTEREST IN, AND ENHANCE THE KNOWLEDGE AND UNDERSTANDING OF THE SCIENCES.

Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. A Schedule J breakdown is as filed: base pay, bonus, other, deferred compensation and nontaxable benefits from this organization, with any from related organizations beside each, and the filer's own total. It is shown with the Part VII listing of the same name on the same return. The form gives no key between the two, so that pairing is ours, and is marked matched by us. Earlier years are each on their own filing page.

The four totals the IRS asks for on Part I of the Form 990, as filed. A dash means the figure was not present on the return — not that it was zero.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all. Showing the 10 most recent; the API carries the rest.

Grants made

No itemized grants to organizations. Schedule I is filed only by organizations that granted more than $5,000 to a recipient, so most filers have none.

Grants received

Other IRS files

Auto-Revocation List

Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.

Publication 78

Listed as of 13 October 2026, under deductibility PC.

These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.

What this page reflects

The registration facts above come from the IRS Business Master File published 13 October 2026 and read 1 November 2026, for every organization at once. Returns through tax year 2024, the newest we have parsed for this organization.
