Here is one compromise I have worked out. The day before winter break (or somewhere right around there) is usually the winter solstice. Its a great opportunity to talk about why and how the seasons change, how the solstice is celebrated around the world, and to review/introduce a key concept in Earth Science.
Now, thanks to technology, we can use a website such as www.daylightmap.com to look at the sunlight on that day. We can then either set it to different times and dates to see the changes, or we can do this several times of year and see the changes. I like to re-introduce it, since this is an area where there are so many misconceptions and confusions, and its so commonly tested on the Regents.
We do an activity near the start of school (fall equinox), winter solstice (before winter break), summer solstice (end of school)---you get the idea. Here is the freebie for Winter Solstice
Or, go to www.daylightmap.com and see what creative things you can come up with on your own! Comment with ideas you have :)
