Summer (June 20 or 21)

This is a 12-minute video explaining the sun's arc through the sky at different points in the year, including the solstice and equinox. (for older elementary or secondary students)

Learn how the shape of the Earth's orbit around the Sun and the Earth's tilt on its axis affect the amount of sunlight we get in winter and summer.

This video asks the question: if 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? It makes a ‘figure 8’ pattern, known as the Sun’s analemma.

This site has a slide show for 7-14 year olds. The slide show answers: when is the solstice, what does solstice mean, and why is this interesting?
