Students will construct graphs from existing weather data sets establishing statistical relationships between air temperature over land in proximity to large bodies of warm water with continuous currents, and construct a model to visually support causality for those relationships. Students will be able to understand that ocean currents can have an effect on local weather conditions, influencing temperature (and precipitation with extended lesson), and use that understanding to make plausible explanations for the differences in temperature and precipitation between two geographically close Florida cities of a similar latitude.
