STEM Traffic Simulation: Can AI Beat Human Thinking?Can your students outsmart artificial intelligence? In this hands-on STEM challenge, teams build a real traffic intersection using toy cars, measure how long it takes 10 cars to get through, then race to improve it — one group using AI research, the other using pure observation and logic. It's competitive, engaging, and surprisingly deep. Students collect real data, calculate percentage improvement, and discover that fixing one problem often cr
