The Antarctic ice sheet changes in size over the course of a year. When it is summer in the southern hemisphere, the ice sheet decreases in size. As the ice sheet melts, it releases fresh water into the ocean. In the southern winter (our summer), the ice refreezes, drawing fresh water out of the surrounding ocean, leaving the salt behind. These seasonal changes in the ice sheet are examined in this ... Full description.

GIS enables students to geo-reference multiple data sets creating layers. This essentially becomes a vertical profile of data, information, photographs etc. that when viewed as a body of information can present a fairly comprehensive view of that location. Based on data associated with latitude and longitude, students now have the ability to examine geo-referenced data sets derived on Earth, and from ... Full description.
