The Sun’s surprising movement across the sky

Published on July 6, 2020 by

Suppose you placed a camera at a fixed position, took a picture of the sky at the same time every day for an entire year, and overlaid all of the photos on top of each other. What would the sun look like in that combined image? A stationary dot? A circular path? Neither. Oddly enough, it makes a ‘figure 8’ pattern, known as the Sun’s analemma. Gordon Williamson explains why in an engaging video about patterns of movement of things in the sky in different times of day.

This video satisfies the 1-ESS1-1 and 1-ESS1-2 requirement for kindergarten proficiency.

Students who demonstrate understanding can:

1-ESS1-1. Use observations of the sun, moon, and stars to describe patterns that can be predicted.

1-ESS1-2. Make observations at different times of year to relate the amount of daylight to the time of year.
