Students perform a lab to explore how the color of materials at the Earth's surface affect the amount of warming. Topics covered include developing a hypothesis, collecting data, and making interpretations to explain why dark colored materials become hotter.
This is a classroom activity about the forcing mechanisms for the most recent cold period: the Little Ice Age (1350-1850). Students receive data about tree ring records, solar activity, and volcanic eruptions during this time period. By comparing and contrasting time intervals when tree growth was at a minimum, solar activity was low, and major volcanic eruptions occurred, they draw conclusions about possible natural causes of climate change and identify factors that may indicate climate change.
This is a short NASA video on the water cycle. The video shows the importance of the water cycle to nearly every natural process on Earth and illustrates how tightly coupled the water cycle is to climate.
This lesson is a lab in which students use thermometers, white and dark paper, and lamps to measure differences in albedo between the light and dark materials. Connections are made to albedo in Antarctica.
This activity introduces students to the process of converting sunlight into electricity through the use of photovoltaics (solar cells). Students complete a reading passage with questions and an inquiry lab using small photovoltaic cells.
Student teams design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy. In this activity, students gain a better understanding of the three different types of heat transfer, each of which plays a role in the solar water heater design. Once the model devices are constructed, students perform efficiency calculations and compare designs.
Students investigate passive solar building design with a focus on heating. Insulation, window placement, thermal mass, surface colors, and site orientation are addressed in the background materials and design preparation. Students test their projects for thermal gains and losses during a simulated day and night then compare designs with other teams for suggestions for improvements.
