I tried to explain seasons to my kids the other day. I got out the globe and asked who wanted the role of the sun and no one wanted it (who knew that was the dud role in this play) so I assigned my older daughter who can stay pretty still.
I glossed over (actually I totally omitted) the part about the sun rotating. Just seemed easier. I assigned the role of Earth to one of my sons and the role of the moon to the other. Then I attempted to get one to constantly face the second while the second turned in circles while going around my daughter and leaning slightly askew.
You can imagine how well that worked.
Then I tried to show them how the rays of the sun would be more direct at one time of the year than at another in out part of the world but the awe of knowing WHY winter is colder than summer didn’t light up their little eyes like I thought it would. I can’t imagine why.
