This activity engages learners to investigate the impact of Earth's tilt and the angle of solar insolation as the reason for seasons by doing a series of hands-on activities that include scale models. Students plot the path of the Sun's apparent movement across the sky on two days separated by three months of time.
Students use Google Earth to analyze oil consumption per capita in the US and around the world. Students then use spreadsheets to create graphs and calculate statistics regarding per capita energy use among various categories.
This short video examines the recent melting ice shelves in the Antarctica Peninsula; the potential collapse of West Antarctic ice shelf; and how global sea levels, coastal cities, and beaches would be affected.
This short video surveys the different current and potential sources of energy - both non-renewable and renewable. It provides some discussion of the pros and cons of the different sources and explains how they are used to produce energy that people can use.
This series of five activities about ocean acidification incorporates real data from NOAA. The activities are organized as a pathway, with five levels increasing in sophistication, and different data-based inquiry activities.
In this mock mission, students become members of a research team and conduct a series of tasks to audit Earth's radiative budget. They use a Java Applet/visual viewer to access satellite data sets, calculate the balance of incoming and outgoing solar radiation, and defend their answers to a number of science questions.
This video is part of the Climate Science in a Nutshell video series. This short video looks at the effects of climate change happening right now around the globe, including: more extreme weather events, droughts, forest fires, land use changes, altered ranges of disease-carrying insects, and the loss of some agricultural products. It concludes with a discussion of the differences among weather, climate variability and climate change.
This video features a short animated sequence that illustrates the difference between young and old carbon released into the atmosphere from the consumption of food (young carbon) and the burning of fossil fuels (old carbon).
In this learning activity, students use a web-based carbon calculator to determine their carbon footprint on the basis of their personal and household habits and choices. Students identify which personal activities and household choices produce the most CO2 emissions, compare their carbon footprint to the U.S. and global averages, and identify lifestyle changes they can make to reduce their footprint.
This video segment describes climate data collection from Greenland ice cores that indicate Earth's climate can change abruptly over a single decade rather than over thousands of years. The narrator describes how Earth has undergone dramatic climate shifts in relatively short spans of time prior to 8000 years ago. The video and accompanying essay provide explanations of the differences between weather and climate and how the climate itself had been unstable in the past, with wide variations in temperature occurring over decadal timescales.
