In this sinusoidal modeling project, students investigate a real-world phenomenon that follows a periodic pattern, such as temperature, tides, daylight hours, or other repeating cycles, and model it using sine or cosine functions. After collecting at least 20 data points, students will create a function that incorporates amplitude, midline, period, and phase shift, then graph their model alongside the data. The project concludes with a written reflection analyzing their process, mathematical dec
