This article presents a number of activities students can do to help them to gain an understanding of the effects of the Earth's tilt on seasons and daylight hours. In addition to simple physical models, the author provides information on how to access an internet database to find sunrise/set times for cities around the US and world to compare how daylight changes throughout the year - a good technological tie-in. I recommend this article for middle and high school teachers looking for ways to help students to grasp this important concept. I think upper elementary students might also be able to do these activities but the database activity would have to be explained well.
