Weather RATS, or Weather Research and Tracking Systems, is a collaborative effort among a national network of K-12 students, their teachers, wireless weather stations, internet data sharing, and professional engineers and meteorologists. Weather Rats is a new way to teach K-12 science and technology by tracking and comparing weather data from schools in Massachusetts, Arizona, Oklahoma, and Puerto Rico. In addition, it is hoped through this enriching project that Weather RATS will inspire many more students, especially girls and minorities, to pursue careers in science and engineering as a result of this project.
