In this online Flash game, learners take to the skies in a hot air balloon and are challenged to beat other balloonists' times to the finish line without crashing. Learners use their knowledge of air temperature and updrafts and downdrafts caused by different geographic features to pilot their balloon in this sky-high competition. These terms are defined in the help tab and can be accessed at any time during the game. There are also three levels of play (easy, medium, hard).
