Short Lessons About the Longest Day of the Year

It is going to be over 90F here in Maine today. That temperature will make it feel like summer a few days before the summer solstice. Many refer to the summer solstice as the "longest day of the year" when they really mean "longest period of daylight in a day."

SciShow Kids offers a nice video that can help K-3 students understand why the length of daylight changes throughout the year.


Reasons for the Seasons is a TED-Ed lesson appropriate for upper elementary and middle school students. The lesson explains the relationship between the shape of the Earth's orbit around the Sun, the Earth's tilt on its axis, and how those affect the amount of sunlight on different areas of the Earth.


And for a little perspective on winter vs. summer solstice here's a great side-by-side time-lapse of the winter and summer solstices in Manchester, England.
