I find the sudden conclusion at the end of the video that the earth revolves around the sun to be too unpredictable and unexplained, based on the other content presented through the video. There will be those that won't understand the video because the presentation assumes a knowledge that there is a change in frame of reference between the solar-system to earth-surface frames. The whole episode is presented from the solar system perspective away from the earth, because that does aid in describing the state of the Earth system, but it's not going to be immediately clear to a viewer how the effects of that perspective applies to their particular location or perspective on the Earth, because of the way the episode has been written. Like, the fact that a hemisphere 'leans' toward the sun during a season clearly has the effect of longer sunlight days during that season, but it isn't clear how that has any relevance to the main conclusions. The final conclusions feel like an idealised conclusion of what you would like to have kids learn from the episode, but due to limited explanation time for concepts, it's been cut short and left to the student to feel that they are stupid because they don't understand what have been presented as simple concepts of the earth's revolutions.
