Activate! is a website, a curriculum, and a space for playing, designing and sharing games. Activate! uses the lens of game design and the related tools of iterative design and programming to strengthen Science, Technology, Engineering and Math (STEM) skills and develop stronger issue literacy on environmental and energy-related topics. Activate! is targeted for youth between the ages of 13 and 18. The Activate! site enables youth to make games using the game development tool "Game Maker." While Activate! can be used online by youth individually, it can also form the core of classroom and/or after-school programs. rograms.
