How to explain the sun earth and moon rk

Today I will be telling you about the sun earth moon seasons moon phases and tides

We get seasons because the earth is on an axis of 23.5 degrees and since it is revolving around the sun which means that the sunlightwill be hitting the earth at different angles which creates seasons

This is my classmates doing the experiment I believe that early in the day the shadow is long then the time around noon it is a shorter shadow then letter it gets longer again then it goes sideways !

I wasn't here for this lab but it looked very fun but since I wasn't there I can't explain it

This is our tides and how the moon effects tides the moon effects tides because the moons gravity pulls it and we look at a graph to figure out the tides what time they occur and how many ft they are

This is some other evidence that we studied seasons this was supposed to represent the earth going around the sun and the seasons come because sunlight hits the earth at different angles
