The New York Science Museum is located in the Flushing Grassland of Queens, New York, which was once the exhibition site of the 1964 New York World Expo. After the Expo, the only science museum in New York was built as a base for New York science popularization. The Science Museum now has more than 400 exhibits related to chemistry, physics and biology, mainly for young people and young children for cloth exhibitions and open visits, and many students are seen visiting the museum under the guidance of teachers (maybe volunteers) and appreciate this learning method.
