32. NASAExplorerSchools Temperature and Earth Climate: Modeling Hot and Cold Planets Learning Objectives By the end of this activity, students should be able to: Describe an equilibrium temperature. Identify the factors leading to an equilibrium temperature. Relate the temperature of an object to the energy it emits. Relate the temperature of an object to the reflectivity of its surface. Identify major energy inputs and outputs of a system. State and apply the Law of Conservation of Energy. Qualitatively relate “distance from the source” to the “energy incident upon an object.” Describe relative strengths and limitations of physical and computer models.
