Exploring Ecosystems and the Atmosphere in the K-12 Classroom: A Plan to Integrate NASA Carbon Cycle Science with GLOBE

在K-12课堂上探索生态系统和大气：将NASA碳循环科学与GLOBE结合的计划该项目是新罕布什尔大学、NASA北美碳计划（NACP）以及捷克共和国与GLOBE社区的科学家和教育工作者的合作。通过对当地环境的探究式调查，GLOBE中小学生将了解全球碳循环及其对气候变化的影响。该项目的核心活动是一个教育项目，其结构类似于研究碳循环的科学项目。这些调查是随着复杂程度的增加而分层的，供高年级的学生使用。学生和教师参与的活动利用生态实地测量、模拟森林生态系统碳、水和氮动态的简化生态系统模型、遥感工具包和一套使用研究人员收集的数据的练习。该项目正在使用三项现有的GLOBE协议（土地覆盖、物候学和土壤），并正在制定“植物生物量和生产力”和“叶片性状”两项新协议。一些基于这些协议的学习活动正在创建，新的数据分析工具将使学生能够根据他们的植物生物量测量来估计地上碳储量。一个简化的生态系统模型（PnET-GLOBE）将允许学生操纵对碳循环敏感的变量，该模型是从科学界使用的更复杂的模型改编而来的。此外，正在创建新的工具，协助学生分析遥感数据和碳塔通量数据。正在开发的城市生态系统的具体活动将有助于该项目接触到更多样化的受众。通过这些活动，学生将提高他们的环保意识，并建立更强的分析和建模技能。

Exploring Ecosystems and the Atmosphere in the K-12 Classroom: A Plan to Integrate NASA Carbon Cycle Science with GLOBEThis project is a collaboration of scientists and educators from the University of New Hampshire, NASA's North American Carbon Program (NACP), and the Czech Republic with the GLOBE community. Through inquiry-based investigations of their local environment, GLOBE elementary and secondary students will learn about the global carbon cycle and its implications for climate change. The core activity of this project is an educational program that is structured like a scientific program to investigate the carbon cycle. These investigations are tiered with increasing levels of sophistication for use by students in higher grade levels. Students and teachers engage in activities that utilize ecological field measurements, a simplified ecosystem model that simulates carbon, water and nitrogen dynamics of forest ecosystems, a remote sensing toolkit and a set of exercises that use data collected by researchers. The project is using three existing GLOBE protocols (land cover, phenology, and soils) and is developing two new protocols for "Plant Biomass and Productivity" and "Leaf Traits." Several learning activities based on these protocols are being created and new data analysis tools will enable students to estimate aboveground carbon storage based on their plant biomass measurements. A simplified ecosystem model (PnET-GLOBE) that will allow students to manipulate variables sensitive to the carbon cycle is being adapted from a more sophisticated model used by the scientific community. In addition, new tools are being created to assist students in analyzing remote sensing data and carbon tower flux data. Specific activities for urban ecosystems being developed will help this project reach a more diverse audience. Through these activities, students will increase their environmental awareness and build stronger analytical and modeling skills.
