Earth science experience

Science experiments, online field trips, and links to science and technology centers worldwide. Explore the Earth Science and Biological Sciences experiments to learn more about carbon chemistry. 

This chapter first presents a review of the rapidly developing range of MC-ICP-MS instrumentation available, then briefly surveys the initial experiments and associated methodologies that have helped to characterize the current and predicted performance of this kind of mass spectrometer, and concludes with a description of the exciting research areas, previously considered to be intractable, that are now developing in the earth sciences, cosmochemistry, oceanography, and the life sciences as a direct consequence of this technique. 

The National Science Education Standards recommend that students have experience grappling with issues that society must ultimately resolve. This publication examines such issues in the fields of biology, chemistry, physics, Earth science, technology, and mathematics. Each issue is presented in two parts The first part is written for the teacher and contains background on the science of the issue and presents alter-...

This book is the product of 40 years of distilled experience teaching quantum theory to juniors, seniors and graduate students. It is intended as a less weighty text for one semester of the physical chemi stry sequence or for a stand-alone course in quantum mechanics for students of chemistry, materials science, molecular biology, earth science and possibly even physics.

Figure 5 Sea-Viewing Wide Field-of-View Sensor (SeaWiFS) satellite image of an iron-induced phytoplankton bloom in the Southern Ocean. The bloom is apparent as a chlorophyll maximum near the center of the image (66°S, 172°E) large, contiguous white areas represent cloud cover. The image was captured on day 20 of the SOFeX South patch experiment. Coordinates are degrees South and East.

Our plan was to create a prototype LAN system and demonstrate it in a public school using an earth science curriculum. A year-long formative experiment was completed in June, 1987. A LAN connected the 25 Apple lie computers in the school to a hard drive which allowed for central storage of data, text, and programs. The Bank Street Writer word processing program was enhanced with an electronic mail system. The Bank Street Filer was another basic tool which made it possible for students to create databases which could be accessed from any computer in the school [12]. 

The importance of space stations as research laboratories for both space and earth sciences was realized long before the first station was launched, which may account for the continuation of space station programs. However, space stations are important for many other reasons. First, space stations allow national and international space agencies to expand and improve on their knowledge of space environments and the potential of space stations as semipermanent or even permanent habitats for humankind. Second, space stations offer an unprecedented opportunity for nations to experience a form of diplomacy and sharing of resources that could serve as a future model of foreign relations. Third, if the quest for new ways to understand the environment is to continue, that search must be extended into space to maintain an essential perspective that had been unavailable. Space stations are invaluable tools for extending the ways humankind learns about itself and its environment.
