The seasons: light intensity and latitude
This Teaching Astronomy and Space video clip, from the Institute of Physics (IOP), Teachers TV and the Science and Technology Facilities Council (STFC), shows a simple demonstration to explain why regions at the equator are hotter than regions nearer the Earth's north and south poles.
Using a lamp and a board, it is easy to show how the angle of sunlight hitting the ground influences its intensity and therefore the amount of energy it carries. Equatorial regions have a greater intensity of light, and are therefore hotter, than regions positioned away from the equator.
