This document outlines a unit plan for exploring cyclical motion and trigonometry concepts across chapters 3 and 5. It includes examples of cyclical motion, project objectives to understand sine functions and represent real data mathematically. Activities are described to search for examples online, collect spring lab data to graph and model with regression, and create a report using presentation software. A final project involves using mathematics to represent a real-world situation of cyclical motion in a PowerPoint presentation with examples provided.
