CRPA: Glaciers: A Chronology of Climate Change

冰川：气候变化年表是CRPA的一个项目，旨在解释气候变化背景下冰川的历史循环。通过使用化学同位素(铍10)，可以相当准确地确定后来被冰川冰覆盖并暴露在阳光下的岩石的年龄。通过这种方法，已经确定了过去7万年的冰川周期。该项目由哥伦比亚大学的拉蒙特-多尔蒂地球天文台和美国自然历史博物馆(AMNH)合作，旨在影响成人观众、6-12年级的青少年和大型教师。研究成果将通过8分钟的高清电影在AMNH及其附属博物馆的“科学简报”部分进行大屏幕观看。将使用严格的前端评估来为演示文稿提供信息并评估观众影响。随后的形成性评估旨在衡量这部电影的学习影响和对长期概念的保留。预计将有超过70万人通过教育电影和网站获得关于冰川循环和气候变化的最新、科学准确的数据和相关信息。教师可以很容易地获取材料，这部电影将有英语和西班牙语的闭路字幕。

Glaciers: A Chronology of Climate Change is a CRPA project that seeks to explain the historical cycling of glaciers in the context of climate change. By using chemical isotopes (Beryllium 10), the age of rocks that have been covered with glacier ice and exposed to sunlight later can be determined fairly accurately. Through this method, the glaciation cycles have been determined for the last 70,000 years. In collaboration between the Lamont-Doherty Earth Observatory at Columbia University and the American Museum of Natural History (AMNH), this project is designed to impact adult audiences, youth in grades 6th-12th, and teachers writ large.The research results shall be expressed via an eight-minute high definition film for large screen viewing in the "Science Bulletins" section of the AMNH and the affiliated museums. A rigorous front-end evaluation will be used to inform the presentation and assess audience impact. Subsequent formative evaluations are designed to measure the learning impact of the film and the retention of longer term concepts.It is anticipated that more than 700,000 individuals will have access to current, scientifically accurate data and related information on glaciation cycles and climate change through the educational film and website. Materials will be easily accessible to teachers and the film will be closed captioned in both English and Spanish.
