The Children's Museum of Science and Technology (CMOST)

Cultural Museums and Collections
Welcome to CMOST – CMOST staff

Since its founding in 1954 as the Rensselaer County Junior Museum, CMOST has evolved to keep pace with the surrounding area. As area children, and children across the country, continue to fall behind the rest of the world in scientific and mathematics-based disciplines, a decision to focus on science and technology was made at the beginning of the millennium. This new commitment to specific disciplines combined with our decades of experience in informal “edutainment” make CMOST the ideal partner for teachers and parents in helping to educate the next generation of leaders. Our location in the heart of New York’s “Tech Valley” only further emphasizes the importance of our mission.


The Children’s Museum of Science and Technology (CMOST), ranked one of the top 20 science centers in the nation by Parents magazine, is the only science center in Tech Valley specifically designed for kids and their families to explore, discover and imagine the world of science together. CMOST inspires young minds to engage in a lifelong exploration of science and technology, instilling a sense of wonder and discovery.

Don't Miss This When Visiting

Here at CMOST we understand the way to keep kids interested in science is by keeping things new and cutting edge so we opened Operation W.I.L.D. - Working in the Living Domain, an exhibit allowing our young visitors to experience our large live animal collection in representations of their natural habitats at CMOST. Recently we added Our River, Our Responsibility to the Hudson River exhibit, with the purpose of educating kids and their families how to be proactive in protecting the Hudson River Valley from invasive species. With the help of GE we also expanded the Go Power - Naturally! exhibit by adding the Outdoor Solar classroom that not only increases our school group capacity but also utilizes the classroom as a teaching tool on green energy technology.The Museum also features several other exhibits including a 75-foot long living Hudson River exhibit, a Hudson River Watershed exhibit, a state-of-the-art interactive weather center where kids can do their own digital weather forecast and see themselves on TV. Several different dome shows focusing on space exploration and molecular science are shown daily in the Lally Digital Dome and Planetarium.
