EGK Tornado AR STEM is an innovative augmented reality application designed to provide an immersive, hands-on learning experience about tornadoes and their impact on communities. This app transforms abstract scientific concepts into tangible, interactive 3D simulations that can be explored in your own environment.

The curriculum is structured as a 5-week AR journey, where each week unveils a new, critical aspect of tornado science and human resilience.

Week 1: The Formation of a Tornado. Users will place an AR model of a developing supercell thunderstorm. The simulation will visually break down the key atmospheric conditions required for a tornado's formation, including warm moist air, cool dry air, and wind shear. Users can tap on different elements like the updraft and mesocyclone to see detailed animations and learn their scientific roles.

Week 2: The Tornado. This week focuses on the powerful vortex itself. The AR model will be a dynamic tornado, allowing users to scale it up and down and rotate it to understand its structure. The app will provide data overlays, such as wind speed and pressure gradients, helping to explain the physics behind the destructive force. This is a core STEM learning module.

Week 3: Simulation of a Tornado Swiping a Town. This is a powerful, yet educational, simulation of a tornado's impact. Users will place a virtual town model and watch as the tornado interacts with it. This module highlights structural engineering principles and the importance of storm shelters and safe rooms. The simulation is designed to be informative, not frightening, emphasizing the science of destruction and safety.

Week 4: Aftermath of a Tornado Swipe at Mayfield, 2021. This module is based on the real-world event in Mayfield, Kentucky. Users will see a photorealistic reconstruction of the aftermath. This segment emphasizes the human element, discussing meteorology and the role of emergency services. It encourages empathy and understanding of community impact. The AR experience will include pop-up text and images detailing the specific events and recovery efforts.

Week 5: The Rebuilding of Coal City, Illinois. This final week focuses on resilience and civil engineering. Users will witness the virtual rebuilding of a town, showcasing how communities can recover and adapt. The AR model will demonstrate tornado-resistant building techniques, such as reinforced concrete safe rooms and improved roof-to-wall connections. This module serves as a powerful message of hope and preparedness, reinforcing the applied science and engineering principles learned throughout the previous weeks.

The application leverages the power of RealityKit to create stunning, realistic AR experiences. It features an intuitive SwiftUI interface that allows for seamless navigation between weeks, interactive models, and a built-in quiz to test knowledge. This app is perfect for students, educators, and anyone interested in meteorology and natural disaster science.
