Exploring Illumination and the Inverse-Square Law with Arduino.

The article discusses the integration of physics principles, engineering, and computer programming in pre-college classrooms. It highlights the importance of implementing integrated activities that incorporate physics concepts, engineering, and computer science to broaden STEM opportunities and increase students' interest in these disciplines. The article presents a unit that allows students to explore the inverse-square law by designing and building an illuminance-distance sensor using Arduino microcontrollers. The unit follows a five-phase instructional model and includes engaging students in discussions, exploring the relationship between illuminance and distance, explaining the concepts through data analysis, and evaluating and presenting findings. The article emphasizes the benefits of this approach in teaching STEM skills and habits of mind. [Extracted from the article]
