In this activity, learners use multiple thermometers, placed at different angles, and a lamp to investigate why some places on Earth's surface are much hotter than others. Learners will create an experiment and record their findings in a data table to discover the importance of the angle of incidence. Step-by-step instructions are included with photos along with safety recommendations. Activity guide includes a "What's going on?" explanation and connections to relevant science concepts like sunlight and the resulting temperature on Earth's surface using helpful diagrams.
