I've mentioned before that we are studying world geography and cultures this year. It is actually called Exploring Geography and Cultures by My Father's World curriculum, and we love it! The studies are divided up by continent, and incorporate the ecosystems, climate, and animals of each continent for the science portion, as well as geography, a brief history, and culture for select countries. We also learn about missionaries who worked in the various countries. It's an all around fun time, as we enjoy learning about people and nature. :) Oh, and trying new foods from other countries is a pastime of ours, so that works in well, too.
