This textbook chapter reviews the scientific evidence for global warming, presents proxy climate data, and discusses the increase in scientific knowledge as evidenced in the series of IPCC reports since 1990. The likelihood of a globe with doubled... (View More) atmospheric becomes CO² concentrations and the possibility of reaching a climate tipping point is discussed. The resource includes two classroom investigations, student worksheets, links to current news articles, and a suite of pre- and post-unit assessments. A teacher's guide supports classroom use. This is the seventh chapter in the unit, Climate Change, which addresses the question of how human activities are changing Earth's climate. The resource is part of 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 lab activity, student teams hypothesize which source has a greater becomes CO² concentration: their breath, auto exhaust, or air in the classroom. They test gas samples from each of these sources, plot data, and hypothesize about the... (View More) respective role engine exhaust and animal respiration play in contemporary climate change. The lab procedures require Bromthymol Blue indicator solution (BTB), household ammonia, vinegar, and balloons. Links to videos supporting the investigations are provided. This activity is supported by a textbook chapter, "How is Carbon Dioxide Measured?," 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.

This quantitative experiment involves lab teams in comparing a sample of room air with one of the greenhouse gases - carbon dioxide, nitrous oxide, or methane - and measuring their heat capacity. The activity requires an infrared heat source, such... (View More) as a heat lamp, two 2L beverage bottles, #4 one hole rubber stoppers, and a thermometer or temperature probe, volumetric flasks, a graduated cylinder, and tubing. Nitrous oxide can be obtained from a dentist, methane from gas jets in a chemistry lab, and becomes CO² can be generated using vinegar and baking soda. A worksheet guides student calculations of heat capacity of the different samples. The investigation s is supported by the textbook, Climate Change, part of the Global System Science, 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.

This experiment has student teams comparing a sample of room air with one of the greenhouse gases - carbon dioxide, nitrous oxide, or methane - and observing the relative effectiveness of the gases in trapping infrared (IR) radiation. The activity... (View More) requires an IR heat source, such as a heat lamp, two 2-liter beverage bottles, #4 one hole rubber stoppers, and a thermometer or temperature probes. Nitrous oxide can be obtained from a dentist, methane from gas jets in a chemistry lab, and CO² can be generated using vinegar and baking soda. Students compare the heating and cooling curves in data they collect. The investigation is supported by the textbook, Climate Change, part of Global System Science, 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.

This activity has two purposes: challenge the learner to develop a procedure for investigating a research question and to learn more about factors affecting the dynamics of air in motion. It demonstrates that warm air and cold air differ in weight... (View More) and this difference affects air's vertical movement in the atmospheric column. Resources provided to students for this challenge include a homemade balance beam made of wood, two paper bags, a desk lamp, paper clips, tape and a thermometer. The resource includes background information, teaching tips and questions to guide student discussion. This is the chapter 8 of Meteorology: An Educator's Resource for Inquiry-Based Learning for Grades 5-9. The guide includes a discussion of learning science, the use of inquiry in the classroom, instructions for making simple weather instruments, and more than 20 weather investigations ranging from teacher-centered to guided and open inquiry investigations.
