Water in the Earth System (WES): An NSDL K-12 Collection Project

围绕“地球系统中的水”（Water in the Earth System， WES）这一主题，正在创建一系列K-12数字教材和资源，以提高K-12教师、学生和家长在课堂、家庭和非正式学习环境中轻松查找、获取和使用高质量、基于标准的水资源的能力。收集了大约500个典型的K-12水资源（科学，经济和政策），用于调查和了解重要的水概念，过程和问题。资源材料和相关的工具和服务由K - 12教师与大学科学家和教育工作者合作确定、审查和编目。这些人正在与许多其他组织密切合作，包括：联邦和州政府机构，专业科学和教育协会，学术机构和中心，以及其他几个国家SMETE数字图书馆项目。该项目的重要共同资助由美国国家科学基金会地球科学理事会的地球科学部提供。

A collection of digital K-12 materials and resources built around the theme of "Water in the Earth System (WES)" is being created to enhance the ability of K-12 teachers, students, and parents to easily find, access, and use high-quality, standards-based water resources in their classrooms, at home, and in informal learning environments. The collection of approximately 500 exemplary K-12 water resources (scientific, economic, and policy) is being used to investigate and learn about important water concepts, processes, and issues. The resource materials and associated tools and services are identified, reviewed, and cataloged by K - 12 teachers in collaboration with university scientists and educators. These individuals are working closelywith a number of other organizations including: federal and state government agencies,professional scientific and education societies, academic institutions and centers, andseveral other National SMETE Digital Library projects.Important co-funding of this project is being provided by the Division of Earth Sciences in NSF's Geosciences Directorate.
