Students will be introduced to the causes, locations, and hazards of landslides, as well as the role of satellite observations in predicting and studying them. To begin, students investigate the amount of precipitation sufficient to cause a... (View More) landslide in two different mediums (soil and sand), then use their findings in follow-up activities. After the lab, students will think about how rain information can be collected, especially via satellites, to model where landslides will occur. Finally, students will look at areas currently at risk of landslides and research landslide hazards and how to prepare for a landslide event, and create a public service announcement sharing that information. This lesson uses the 5E instructional model. All background information, student worksheets and images/photographs/data are included in these downloadable sections: Teacher’s Guide, Student Capture Sheet and Lab Instructions and PowerPoint Presentation.

In this lesson students investigate the effects of black carbon on arctic warming and are introduced to a mechanism of arctic warming that is not directly dependent on greenhouse gases in the atmosphere: black carbon deposition on Arctic snow and... (View More) ice. It can also be used to introduce the concept of albedo. Prerequisite knowledge: students understand the concepts of absorption and reflection of light energy. This lesson is designed to be used with either an Earth/environmental science or chemistry curriculum. It may also be used as an enrichment activity in physics or physical science during a unit on energy. Includes suggested modifications for students with special needs and low technology option. Requires advance preparation, including freezing ice samples overnight. (View Less)

Students will explore how energy from the sun is absorbed, reflected and radiated back into space by Earth. By completing three short labs investigating the effects of surface color, type of material, or cloud cover on temperature change, students... (View More) will begin to consider how various surfaces might affect Earth's overall temperature. Earth's energy budget will then be explored through a video, simulation activity, and an interactive animation. This lesson uses the 5E instructional model. All background information, student worksheets and images/photographs/data are included in these downloadable sections: Teacher’s Guide, Student Capture Sheet, PowerPoint Presentation and three lab sheets.

This online lab exercise focuses on the causes, characteristics and effects of the glacial-interglacial cycle. The sixth in a 10-part lab series on weather and climate, this lab exercise is designed for first and second year college geoscience... (View More) students (majors and non-majors) as well as pre-service STEM teachers. (View Less)

This online lab exercise focuses on the processes involved in the Carbon cycle and the influences of human activity on those processes- especially as they relate to Earth's weather and climate. The fourth in a 10-part lab series on weather and... (View More) climate, this lab exercise is designed for first and second year college geoscience students (majors and non-majors) as well as pre-service STEM teachers. (View Less)

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.

In conjunction with discussions on atmospheric CO2, timescales, and proxy data, students will make, dissect, and analyze an ice core. The activity allows students to study changes in Earth’s atmospheric composition and temperature on millennial to... (View More) orbital timescales. The lesson includes instructions for making the ice cores (requires up to a week), worksheets, resources and a short assessment. (View Less)

In this laboratory activity, students observe what happens when a fluid of one density is placed in a fluid of a different density. The fluids are salt water and fresh water, cold water and warm water. They generalize their results to describe what... (View More) occurs in the world's oceans to drive the global conveyor belt pattern of ocean currents. There is an option to conduct an investigation taking quantitative measurements, which requires an immersible thermometer and a heat source. Assessment suggestions are included. The investigation is found in the teacher's guide accompanying the textbook, Climate Change, part of Global System 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.
