Mentoring and inquirY using NASA Data for Atmospheric and earth science for Teachers and Amateurs (MY NASA DATA) is a project to enable K-12 teachers and students, as well as citizen scientists, to explore the large volumes of data that NASA collects about the Earth from space. Students use scientific inquiry and math skills as they access and display microsets of the Earth System. A microset is a small amount of data - perhaps a single parameter for the whole globe; or a time series for a single location - extracted from a much larger data file. It is in a simple format, such as plain text, or accessible through a user-friendly tool. Most of the data are global at a typical resolution of 1 degree in latitude and longitude. In addition to the microsets, the MY NASA DATA website offers a collection of lesson plans to help you get started with data exploration. Some were developed by the team, while others have been contributed by educators who have used the MY NASA DATA website. All lessons identify relevant national or state education standards.
