How do day/night and the seasons work?

New ELI today - 'Earth on Earth; using a globe in the sunshine to show how day/night and the seasons work'. 

Pupils can use the ‘globe in the sunshine’ to:
  • explain how the half of the Earth bathed in sunlight at any one time is experiencing day, whilst the other half is experiencing night; 
  • point out and explain the day/night dividing lines of dawn and dusk; 
  • show how equatorial regions are warmer (and feel warmer) than polar regions because the Sun is nearer to being overhead and so the rays are more concentrated
  • point out and explain how polar regions are lit in the summer but are in darkness in the winter.
