This activity models the necessary balance of creating power and cleaning up its associated waste. Learners participate in a game where they attempt to move forward toward a goal. For the power generated (step forward) they gain some waste (inflated balloon). Learners must manage the waste (discard balloons), before they can continue to generate power (move forward). When learners set up a free account at Kinetic City, they can answer bonus questions at the end of the activity as a quick assessment. As a larger assessment, learners can complete the Smart Attack game after they've completed several activities.
