Air pollution working model with lights, in this course introduces students to the concept of air pollution and its harmful effects on the environment and human health through a creative science project. In this course, learners are guided step by step to design and build a working model that demonstrates how pollutants affect air quality, using simple materials like cardboard, LEDs, small motors, and colored papers. The model incorporates lights to show the difference between clean air and polluted air—green or blue lights symbolizing clean air, and red or yellow lights representing pollution levels. Students will also learn about common sources of air pollution such as vehicles, factories, and burning waste, and how these contribute to smog and health problems. The course emphasizes both theoretical and practical learning, combining environmental science with hands-on skills in electronics and design. By the end, learners will understand the impact of air pollution, explore possible preventive measures, and create an engaging model suitable for school presentations and science fairs. howtofunda
