The reason to teach about these things is that in practicing developing and testing hypotheses, it builds up our skills to understand other systems. So this kind of material should not be rote learned, it should be investigated.<br>
<br>
As Maria suggests, it might be even better practicing hypothesis testing on systems more relevant to us. The seasons probably made more sense a century ago as a system on which to practice understanding. We were much more affected by the seasons then and lived in a far simpler world. Today, maybe we should practice understanding on the internet or television or whether the moon landing was an elaborate hoax on a sound stage.<br>

For example, students may plan settling Mars and investigate the role of eccentricity in seasons there and on Earth. </div>
<div><br></div><div>The question, "Why are there seasons?" should be answered with, "Why do you need to know?" - which allows students to investigate the matter in some context, for themselves, and check their answers for REASONable-ness within that context.</div>

The challenge for teachers is to share our love of understanding things, not so much a love of learning but a love of understanding. The joy of building robust hypotheses of how things work.<br></blockquote><div><br></div>
<div>Tony, the pure joy of building robust hypotheses of how things work, just to understand, is mostly a male thing. The joy of figuring out reasons why things work, so as to make sense of personally and socially relevant contexts, is mostly a female thing. I call for balance, and for accommodations to students who prefer one over the other.</div>

Another challenge: why is it colder in the mountains?<br>
