This Saturday—June 20, 2020—marks the official beginning of summer in the Northern Hemisphere, with the occurrence of the June solstice. In celebration, we’re focusing this week’s Distance Learning offerings on seasons. Today we’ll revisit a previous lesson about what causes the Earth’s seasons—with bonus content added to focus on the solstices!

In this timely multimedia lesson, we explore what causes Earth’s seasons, and what it means to experience an equinox.

Geared toward upper elementary-level students.
