Show caption HideA screen-shot from Google Earth showing chlorophyll concentrations in the equatorial Pacific. This is the data that students use in the exercise. Details In this activity, students are split into groups and assigned different ocean regions. These include the Arabian Sea, Equatorial Pacific, North Atantic, and Southern Ocean. Each group uses Google Earth to view NASA satellite chlorophyll imagery and the cruise track of data collected as part of the U.S. Joint Global Ocean Flux Study. At three locations along each cruise track, chlorophyll-temperature-depth (CTD) and bottle data collected as part of the study can be downloaded. Students work with the data to identify oceanographic features as a function of depth and then make simple calculations.
In the second component of the exercise, monthly mean chlorophyll a satellite imagery is also included and students speculate about the annual cycle of physical and biological processes based on that time series. Students compile the results into a presentation for the class. Each group should have different responses to the questions asked and different results for the calculations because each ocean region is very different. This easily leads into a discussion about the major ecological provinces of the ocean and what factors cause variability.

In this activity, students identify spirals and other shapes present in nature and discuss at what sizes or scales these shapes exist. Examples include a hurricane, foraminifera, nautilus, and a galaxy. They will discuss the differences and similarities of each of these spirals and investigate the powers of ten that identify the scales at which these different examples exist.

This experiment uses the heating of water to explore the concepts of density and volume. Students learn about the transfer of heat energy within the atmosphere, hydrosphere, and Earth's interior, and connect this transfer to differences in density, which in turn result in motion. As part of the investigation, students will also become familiar with the Celsius and Fahrenheit temperature scales.

In this activity, students conduct an investigation to purify water. They engineer a method for cleaning water, discover the most effective way to filter water, and practice conducting a scientific experiment. Through this activity and its associated lesson, student teams follow the steps of the engineering design process related to water treatment, as done by practicing engineers, including constructing and testing their designs.

This article is about the isoperimetric theorem. It states the theorem, explains its history and uses examples and exercises to demonstrate it. The resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

In this video-based activity, students learn that sea level is an average measurement of the height of the ocean, and sea level changes with the seasons and over time. El Niño and La Ninña events are compared, demonstrating that sea height is a function of temperature.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.

The following topical questions and selected resources are designed to guide you through the current debate on the origin of Yellowstone hotspot: does it originate from processes operating only in the shallow portions of the Earth's mantle, or from a deeper-seated feature, perhaps a mantle plume generated at the core-mantle boundary? The resources linked from this page include an assortment of web- and non-web resources, published papers, abstracts, and graphics. Direct links to web resources are followed by a "more info" link that gives a short description of the web resource. These resources by no means comprise a comprehensive treatment of the literature on the subject, but should at least give you a place to start in your study of the origin of the Yellowstone hotspot.
