This standards-based Real Time Data Module was created by the Center for Improved Engineering and Science Education (CIESE) for use by students in the elementary grades to allow them to investigate weather phenomena both locally as well as in other places around the world. By using hands-on activities and real-time data investigations, the students will develop a basic understanding of how weather can be described in measurable quantities, such as temperature, wind and precipitation. The site features a Teacher Area containing lesson plans, curriculum standards, guidelines for data collection, and a list of children's books with weather-related themes.
