These three activities discuss the special method the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) spacecraft uses to make images of high energy X-rays and gamma rays from the Sun. Activity 1 demonstrates how scientists can use the HESSI rotating grids to determine the distance of a flare from the center of the Sun's disk. The position of the flare on the Sun is not completely determined ... Full description.

This project teaches students about the Sun and Solar flares. They build a paper model of the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) spacecraft, launched by NASA to study the Sun in X-rays and gamma rays. Background information about solar flares discusses what they are, where they occur and how often and why we study them. Students also learn how HESSI works. They work in teams ... Full description.

This activity introduces ocean floor mapping and features. It will help students grasp how one can see with sound waves. It will also introduce them to the amount of information contained in sound. The intent is to understand how sonar can help science see the ocean floor. The concept of seeing with all kinds of waves, not just light, can be extended to many areas of science where remote sensing is ... Full description.

This essay describes the effort being made to predict the North Atlantic Oscillation (NAO) and detect any relationship between it and global warming. Students will discover how computer models are being made of the oscillation and the progress that is taking place. They will also learn about the ramifications of making reliable predictions. The site has links to three other essays on the subject as ... Full description.

This site features a video that illustrates both seasonal patterns and long-term changes in sea ice distribution across the Arctic Ocean. It draws data from two satellite instruments that measure emitted microwave radiation, which helps distinguish open ocean from ice. It shows that during the winter months, a layer of ice forms across vast expanses of the Arctic Ocean and each summer, more than half ... Full description.

In this lesson, students will investigate the technological capabilities that are required for the operation of deep sea submersibles and understand the concept of buoyancy. As they proceed, they will research the development and use of research vessels or vehicles used for deep ocean exploration; calculate the density of objects by determining their mass and volume; and construct a device that exhibits ...

In this activity, students construct and use a Secchi dish to measure the relative amount of sediment within a water column. Although simple in design, the Secchi dish (along with its hi-tech equivalents) is used by many marine and freshwater scientists. As the dish sinks, its image becomes obscured. When the dish can no longer be seen, a measurement of the depth to which light penetrates is taken ... Full description.
