Shadows change length throughout the year because the altitude of the Sun above the horizon changes. The altitude (height above the horizon) of the Sun changes as the Earth revolves around the Sun each year. This is due to Earth's axis being at an angle. In the Northern Hemisphere, the North Pole is pointing away from the Sun on the winter solstice (around Dec. 21) and for the Northern Hemisphere the Sun is at its lowest altitude and shadows will be the longest of the year. On summer solstice (June 21), the Sun is at its highest altitude and shadows are the shortest of the year. Janice VanCleave

Why do shadow lengths change thoughout the year?
because the earth is "tilted" 23.5 degrees. So, when earth rotates around the sun, it is either tilted closer, or farther away from the sun. For example, in summer, earth is titled towards the sun, making shadows short. But in winter, earth is tilted farther from the sun. So shadows are longer. That is why shadows are longer or shorter during the year.
