In this kinesthetic activity, students take on roles of either photons or gas molecules. Photons signal a change from visible light to infrared with a piece of folded construction paper, simulating absorption by the Earth's surface and reradiation... (View More) to space. The play is guided by flipping a coin, and students see how stochastic processes result in 70% of visible protons being absorbed and reradiated as infrared. This activity is supported by a textbook chapter, What is the Greenhouse Effect?, part of the unit, Climate Change, in Global Systems Science (GSS), an interdisciplinary course for high school students that emphasizes how scientists from a wide variety of fields work together to understand significant problems of global impact.

In this kinesthetic activity, the concept of energy budget is strengthened as students conduct three simulations using play money as units of energy, and students serve as parts of a planetary radiation balance model. Students will determine the... (View More) energy budget of a planet by manipulating gas concentrations, energy inputs and outputs in the system in this lesson that supports the study of climate on Mars, Mercury, Venus and Earth. The lesson supports understanding of the real-world problem of contemporary climate change. The resource includes a teacher's guide and several student worksheets. This is the second of four activities in the lesson, How do Atmospheres affect planetary temperatures?, within Earth Climate Course: What Determines a Planet's Climate? The resource aims to help students to develop an understanding of our environment as a system of human and natural processes that result in changes that occur over various space and time scales.
