Offset is a mobile application created by NASA. This application would be appropriate for elementary-age students in order to allow them to explore the factors at play in global warming. The retro game allows players to attempt to slow the pace of global warming by cutting back on carbon emissions in a fast-paced environment that requires students to multitask. However, and more importantly, while playing this game, students will learn how the carbon cycle works, about different sources of carbon, and how to offset those sources of carbon in order to slow global warming.
The application can be downloaded from the Apple App Store, or here.
