This resource is a complete lesson that covers the Big Bang Theory for the OCR A Level Physics A course. However, it is useful for other exam boards too.
This lesson teaches the following content:
-the cosmological principle; universe is homogeneous, isotropic and the laws of physics are universal
-Doppler effect; Doppler shift of electromagnetic radiation
-Doppler equation: Δλ/λ ≈ Δf/f ≈ v/c for a source of electromagnetic radiation moving relative to an observer
-Hubble’s law; v ≈ H0 d for receding galaxies, where H0 is the Hubble constant
-model of an expanding universe supported by galactic red shift
-Hubble constant H0 in both km s–1 Mpc–1 and s–1 units
-the Big Bang theory
-experimental evidence for the Big Bang theory from microwave background radiation at a temperature of 2.7 K
-the idea that the Big Bang gave rise to the expansion of space-time
This lesson includes:
-A full presentation including 2 example questions with worked solutions.
-A worksheet with model answers, perfect to set as homework.
-Clear visual aids and diagrams to simplify complex concepts.
-Editable PowerPoint and Word document for easy customisation.
