In this online game, learners build complicated machines to complete simple tasks. The game starts with a power source on one side of the screen and the task on the other side. Learners select machine parts to link together and complete the task. The machine parts follow simple physics rules. 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 Bug Blaster game after they've completed several activities.
