Lesson Plan: Parallax and Trigonometry
This lesson engages high school students in understanding how trigonometry is applied to measure distances using the principle of parallax, a key method in astronomy. Students investigate how a shift in viewpoint creates a measurable angle that, combined with a known baseline, forms a triangle. By applying trigonometric functions and small-angle approximations, students calculate distances to objects, simulating the method astronomers use to determine the distance to nearby stars.
