This diagram from Denmark explains the reason for our seasons.  Most of this you probably studied in school

Equinox comes from two words meaning “equal night.” At the equinox the sun is directly over Earth’s equator and the length of light and dark (day and night) are [approximately] equal.

Solstice comes from two words meaning, “sun” and “to stand still.”  This happens when the sun reaches the farthest northern (or southern) point from the equator.

Indeed if you observe you’ll notice that the length of the day (compared to night) changes most rapidly at the equinox and very slowly at the solstice.  Have you ever observed the differences in where the sun rises and sets?

About 35 years ago, my commute to work included a stretch of wide open expressway.  In the spring and the fall around the time of the equinox, the rising sun would be directly in my eyes as I drove along this part of the road to work.  It only lasted three or four days and then it was off to the left or right and would be higher or lower in the sky and not bother me.

You don’t have to be a home-schooler to teach your children about these things.  AND you don’t have to be a child to learn more.  Use your eyes, be curious, find answers and learn.  It’s fun.  No, really it is. 8)
