“If someone were traveling to our area for the first time during this time of year, what would you tell them to bring to wear? Why?” This question was used to engage students in a guided-inquiry unit about how climate differs from weather. In this lesson, students explored local and national data sets to give “travelers” advice when preparing for a trip to Boston, Massachusetts in the spring. By using personally meaningful investigations to answer a variety of scientific questions related to weather and climate, students deepened their understanding of weather and climate and the factors affecting both.
