IGCSE Physics Lesson Plan

This weekly lesson plan for a Grade 10 physics class covers cosmology and the Big Bang theory over four class periods from July 29 to August 2. On the first day, students will learn about the past evolution of the universe and evidence that supports the Big Bang theory, such as redshift and cosmic microwave background radiation. The second day focuses on how the Doppler effect causes changes in observed wavelength and frequency based on an object's motion. On the third day, students will learn how the redshift of galaxies provides evidence for the expansion of the universe and practice questions involving the Doppler effect. The final class uses examples to demonstrate the Doppler equation relating changes in wavelength to an object's velocity. Students are assigned related homework each night to reinforce the concepts.
