Okay I know this is like 4th grade science or something, but I think with my stroke I just can’t seem to picture why the sun is “on” or “off” for most of the day up at the North Pole or down at South Pole, and yet at the equator days are very regular year ’round.
I keep picturing the Earth on its axis, but I just can’t seem to figure out how the sun shines differently at different latitudes.

The other explanations are good and it sounds like you got it but if you want to visualize or even demonstrate it to literal 5yo children do this:
Place a lamp in the middle of a room, remove any other light source. Get an apple or orange. Let them stab a pen through it. Put a little tack anywhere on it. Then make them slowly walk around the lamp in a circle with the apple. After one circle you say that is a year. Then let them keep walking in the circle and make them slowly spin the pen which spins the apple – tell them to watch the surface of the apple and also the tack which is actually “where they live” and tell them that’s day and night. Then last make them tilt the pen while they keep circling the lamp and spinning the apple and make sure to tell them they keep tilting it in the exact same direction all the time so the tilt is always the same (this is the most counterintuitive step, that the tilt doesn’t change at all as you move around. Like.. make it always face the same corner of the ceiling as they move around). If they struggle take over and show them how you mean that thing with the tilt, then hand the apple back. Then say that makes summer and winter because the days are longer or shorter and the sun is hitting more or less direct. And lo and behold at one of the the poles it’s either “always” day or “always” night for a while.
Or just show them a 3 minute youtube video but that’s fucking lame and they won’t remember.
