How Long is Your Shadow on the Shortest Day?
Many people think of the first day of spring or the first day of school as a new beginning. But the winter solstice is a new beginning, too! Longer days will return, and it won’t be long before your child can play outdoors in the evening again. Try this quick and easy science experiment that explores the peak of wintertime! Explore the concept of a "solstice," explaining that it occurs just twice per year when the sun is at the greatest distance from the celestial equator. You can also explain the occurrence that happens in autumn and spring, of an "equinox," when the sun crosses the plane of the earth's equator—causing day and night to be of equal length.
