Good morning from chilly Paris Hill, Maine where my thermometer reads 11F, but it feels more like 0F. Not only is it going to be cold all day, it’s also going to be the day that we have the least sunlight all year. That is because today is the winter solstice.

Here’s a small collection of resources for teaching and learning about the winter solstice.

PBS Kids Nature Cat has a cute video that explains the basic concept of winter and summer solstice.

TIME recently published a video featuring “four things you probably didn’t know about the winter solstice.” Spoiler alert! You probably knew them, but the video will remind you about those things.

Mechanism Of The Seasons is a six minute video about why the length of daylight we receive in a location changes throughout the year. This video could be helpful in a flipped classroom environment.

Sixty Symbols offers an eleven minute video about equinoxes and solstices. It’s not a video that most kids will find engaging, but I’m including it because in it you can see a demonstration of how you can use the free Stellarium software in your lessons.
