This project uses penguins to hook students into exploring how science investigates changes in Earths biota and climate. The project builds on a pilot effort, called Penguin Science, and will develop PowerPoint presentations, short video "webisodes," background reading material, and live and interactive website components to engage students in ongoing field research. Students, K-14, will be involved in climate-change research that will include ecology, sedimentology, paleontology, glaciology and oceanography. The project will use the amazingly popular Antarctic pack-ice penguins (Adelie and Emperor) to look at biotic responses to environmental change, and address the question: How do we know what we know? Activities include how the changing environment currently and over the previous 12,000 years has affected the population size and distribution of these creatures. The demography and ecology of Adelie and Emperor penguins appear to be particularly sensitive to changes in land-based and marine ice. The response of species to climate change is very complex and polar species are no exception: in some parts of Antarctica they are declining and in others increasing, both trends related to changing ice. However, these responses are well enough understood that ecologists, geologists, glaciologists and oceanographers have used the dated, sequential penguin occupancy of areas as one proxy for ice sheet retreat and advance, as well as changes in sea-ice persistence, during the Holocene. The patterns revealed by penguins corroborate the information from glacier and sediment cores. The project will compare these proxies (how the data are gathered, how they are analyzed, and what they mean) in a way that will be engaging to students.

这个项目用企鹅来吸引学生探索科学如何调查地球生物群和气候的变化。该项目建立在一个名为“企鹅科学”的试点项目的基础上，并将开发PowerPoint演示文稿、短视频“网络集”、背景阅读材料和实时互动网站组件，以吸引学生参与正在进行的实地研究。K-14年级的学生将参与包括生态学、沉积学、古生物学、冰川学和海洋学在内的气候变化研究。该项目将使用非常受欢迎的南极浮冰企鹅（阿德利企鹅和帝企鹅）来观察生物对环境变化的反应，并解决这个问题：我们如何知道我们所知道的？活动包括当前和过去12000年不断变化的环境如何影响这些生物的种群规模和分布。阿德利企鹅和帝企鹅的人口和生态似乎对陆地和海洋冰层的变化特别敏感。物种对气候变化的反应非常复杂，极地物种也不例外：在南极洲的一些地区，它们正在减少，而在其他地区，它们正在增加，这两种趋势都与冰的变化有关。然而，生态学家、地质学家、冰川学家和海洋学家对这些反应已经有了充分的了解，他们已经使用有年代的、连续的企鹅占据区域作为全新世期间冰盖退缩和前进以及海冰持久性变化的一个代表。企鹅揭示的模式证实了冰川和沉积物岩心的信息。该项目将以一种吸引学生的方式比较这些代理（如何收集数据，如何分析数据，以及它们的含义）。
