Navigational tools and methods of early voyagers provide the background and contrast to the satellite images and models used today. Students complete mapping activities based on historical data from Columbus and Blith. Students will also use a computer model of ocean currents to investigate the movement of objects drifting on the ocean surface. Note that this is lesson one of five on the Ocean Motion website. Each lesson investigates ocean surface circulation using satellite and model data and can be done independently. See Related URL's for links to the Ocean Motion Website which provide science background information, data resources, teacher material, student guides and a lesson matrix.

In this activity, students view a satellite image of Earth at night, and consider the environmental considerations and consequences associated with the pattern of light they see. The resource includes a map for student use. Summary background information, data and images supporting the activity are available on the Earth Update data site. To complete the activity, students will need to access the Space Update multimedia collection, which is available for download and purchase for use in the classroom.

In this activity, students are presented with a satellite image of ocean temperature, and examine the map to determine whether ocean temperature is influenced by latitude. Students graph each temperature value as a function of latitude and write a linear equation that best fits the points on their graph. A student worksheet is provided. Summary background information, data and images supporting the activity are available on the Earth Update data site. To complete the activity, students will need to access the Space Update multimedia collection, which is available for download and purchase for use in the classroom.

This two-sided poster presents images and information about ozone. The front features a series of color Earth images; each image reflects total ozone readings taken every October from 1979 to 2012. The poster back contains information about ozone under the following headings: What is Ozone?, Chemistry of the Ozone Layer, Measuring Ozone in the Earth's Atmosphere, Timeline of Stratospheric Ozone Depletion and Observations, How the Ozone Hole Forms, and A World Avoided. In addition, the back contains two activities: Visualizing the Ozone Hole and a Color by Number worksheet.

This ChemMatters article provides a history of the study of ozone, a description of an experimental simulation called "The World Avoided," a brief introduction to the chemistry of ozone, an explanation of how ozone is measured, and the difference between "good" ozone in the stratosphere vs "bad" ozone in the troposhere. ChemMatters is an educational magazine published by the American Chemical Society.

Oceans play a significant role in determining and moderating the effects of energy imbalances. Students will begin this lesson by working with temperature data to reinforce the importance of protocols, practice computing statistical measures of data and interpreting their significance. The lesson continues with investigations into daily and annual energy cycles. Using a sea surface environment visualizer, students then identify patterns of sea surface current and temperature data. Note that this is lesson five of five on the Ocean Motion website. Each lesson investigates ocean surface circulation using satellite and model data and can be done independently. See Related URL's for links to the Ocean Motion Website that provide science background information, data resources, teacher material, student guides and a lesson matrix.

This is an activity about the atmospheric conditions (greenhouse strength, atmospheric thickness) Mars needs to maintain surface water. Learners will use a computer interactive to learn about Mars past and present before exploring the pressure and greenhouse strength needed for Mars to have a watery surface as it had in the past. This lesson is part of Project Spectra, a science and engineering education program focusing on how light is used to explore the Solar System.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"In 2009, 28 world-renowned scientists gathered on a mission: to figure out how to save the planet—or, at least, how far we can push the planet before threatening our survival. The result was a list of nine critical environmental limits below which the Earth’s future would remain safe—by keeping atmospheric carbon low, for example. Exceeding those limits would risk irreversible global damage. But despite providing good science-based measures for monitoring the Earth’s health, these so-called Planetary Boundaries fail to address one very important question: What can you— as a citizen, CEO, city council, or national committee—do to help? That’s where a new approach called Planetary Accounting comes in. The problem with the Planetary Boundaries is that they can’t be directly translated to figures that make sense at smaller scales..."
The rest of the transcript, along with a link to the research itself, is available on the resource itself.

In this learning activity, students compare changes in insolation with changes in surface temperature in the polar regions using scientific visualizations of global data sets. Links to readings related to the shrinking ice cap and albedo are included. This is part 1 of a four-part activity on polar science. Extension activities examining air and sea surface temperature in relation to changing Earth albedo are included. This activity is one of several learning activities connected with the 2007 GLOBE Earth system poster.
