Jan Term 2023 - Scandinavia

Scandinavian countries are consistently ranked as the happiest countries in the world. Jan Term 2023 focused on discovering what it is about these societies that lead their citizens to be so happy. In examining the food, culture, natural beauty, architecture, and daily life in these countries, students explored the basis for their very high life satisfaction ratings. Students learned about the culture and robust welfare systems of Denmark and Sweden (e.g. universal healthcare and free education), contrasting it to their experience in the United States; tried a variety of Scandinavian food that they both loved (Fika and homemade pastries) and could maybe do without for a while (pickled herring and salted licorice); participated in thrilling Arctic adventures like ice skating on a lake, dog sledding, and ice climbing; and were lucky enough to experience the elusive Northern Lights dancing in the sky!
