Wonderful World of Weather

From site:  This standards-based Real Time Data Module has been created 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 lesson plans which make up this module have been designed to allow teachers to select the ones which fit into their curriculum to allow for flexibility in implementation.
