SkySurvey: Using SDSS Data in the Classroom

AST-0225645PI: Szalay， alexanderist：约翰霍普金斯大学授予Szalay博士一笔资金，用于继续扩展、宣传和评估其试点网站Skyserver （http://skyserver.sdss.org）。该网站将斯隆数字巡天（SDSS）的数据免费提供给任何可以上网的人。到2005年完成时，SDSS将绘制出整个天空四分之一的详细地图，确定超过1亿个天体的位置和绝对亮度。它还将采集超过100万个星系和类星体的光谱。Szalay博士建立了一个由天文学家、程序员、科学作家、教育专家和教师组成的团队，以吸引更广泛的受众。他们设计了几个工具，使学生和公众能够轻松直观地访问SDSS数据。他们还设计了几个互动教育项目，让学生利用SDSS数据学习天文学概念。例如，学生们将制作哈勃图来显示宇宙的膨胀，从光谱中计算恒星的温度，并在SDSS图像中寻找小行星。所有项目都将包括教师指南，给出完整的解决方案，对课堂教学项目的建议，以及对国家教育标准的适用性。＊＊＊

AST-0225645PI: Szalay, AlexanderInst: Johns Hopkins University Dr. Szalay is awarded funds at Johns Hopkins University to continue expanding, advertising, and evaluating its pilot website, Skyserver (http://skyserver.sdss.org). This site makes data from the Sloan Digital Sky Survey (SDSS) freely available to anyone with Internet access. By the time the SDSS is finished in 2005, it will have mapped one-quarter of the entire sky in detail, determining the positions and absolute brightnesses of more than 100 million celestial objects. It will also take spectra of more than a million galaxies and quasars. Dr. Szalay has built a team of astronomers, programmers, science writers, education experts, and teachers in order to reach a wide audience. They have designed several tools to allow students and the general public to easily and intuitively access SDSS data. They are also designing several interactive educational projects in which students use SDSS data to learn concepts from astronomy. For example, students will make Hubble diagrams to show the expansion of the universe, calculate temperatures of stars from spectra, and look for asteroids in SDSS images. All projects will include teachers guides that give complete solutions, advice on teaching the projects to a class, and applicability to national education standards. ***
