These students are learning about maps of the world.
     They first compared world maps with globes.  They drew pictures of Antarctica as is it is shown on a globe and then as it is shown on a map.  They compared different types of map projections.  They learned to identify important lines of latitude and longitude (and they regions those lines define) on a world map. 
     In the next lesson, they'll learn to identify directions on world maps, and they'll attempt to make world maps of their pumpkin globes.
