I just watched this and learn something new. I am always interested in learning social science and English. It is a very informative video about seasons..

What grade levels are the middle school science courses for? Are they just 6th, 7th, and 8th and it doesn't matter really or is it different levels?

[@kailynnmclean3639]

I think its all middle school grades

God teaches us we are the center of the world with a great light (Sun) to rule the day, and a lesser light (Moon) to rule the night, our seasons come from the Sun’s rotation north of the Tropic of Cancer June being closest to the Arctic Circle and rotating outward in the winter months closest to the Antarctic circle, below the Tropic of Capricorn

Got it!....maybe.

Question: Why are day and night not reversed in summer and winter when the side of the earth facing the sun changes in summer and winter? Example: In summer, the northern hemisphere is lit on the right or tilted towards the sun. In winter, the northern hemisphere is lit on the left or tilted away from the sun. Since the “north pole” is always pointing towards Polaris, it seems like day and night would be reversed during summer and winter🤷🏻‍♂️ Thank you in advance for any information/explanation🤗

This only makes sense with a close sun and moon using the Gleason map, during the summer solstice the sun is revolving around the northern geocentric region which is how we have a 24-hours of sunlight near the northern pole or the center of the Gleason map. As time goes by, the sun rotates outward towards the Antarctic circle in the winter months giving us shorter days north of the equator. As we live on a stationary Earth

This video is about HOW we have seasons not WHY we have seasons.
