This is an activity about the concept of direct versus indirect sunlight. Learners construct and use a sun angle analyzer to investigate the effect of angle on area illuminated. The fraction of light on each square of the analyzer is then calculated and compared. A discussion at the end relates the results to the amount of sunlight falling on different parts of the Earth and the effect this has on temperature and seasons.
