Whiteboard recap of last lesson: ideas over time.
Match:
Why did it take so long for people to accept the Sun-centred model?
Ask: does the Sun really move across the sky?
It looks like the Sun rises, crosses the sky and sets — but is that what really happens?
True or false: the Sun moves around the Earth.
If the Sun stays still, what must be moving to make it "rise" and "set"?
Explain why it looks like the Sun moves, even though it is the Earth that spins.
Teacher models. Watch how Earth spins.
Swap the clip: change the ID after /embed/ (now zgzC69-bzYc).
Use a globe (or fists) to show the spin and the poles.
Play the animation. Bust the "Sun goes round Earth" myth.
Earth spins on its tilted axis once every 24 hours. The Sun does not move.
Watch for: pupils saying the Sun "goes round us" or "moves across the sky".
