This Purdue University website features measurement tutorials for general chemistry students. Beginning with the subject of Units, thw site teaches users about the English and Metric systems including the prefixes and how to convert from one system to the other. Visiting the Errors link, students can find information about uncertainty, systematic errors, and random errors. At the next link, users can find assistance for adding, subtracting, multiplying, and dividing as well as rounding significant figures. The last link addresses the concept of scientific notation. Within each link, students can also find a few practice problems along with the solutions. [RME]

Brian McNoldy at Multi-community Environmental Storm Observatory (MESO) educates the public about the use of radar in meteorology in this pdf document. After reading about the history of radar, visitors can find out how radar can detect storms by transmitting a high-power beam of radiation. Students can learn how scatter, absorption, frequencies, scan angles, and moments impact the radar display. With the help of many example images, the author also discusses how to interpret the images collected. At the end of the online document, visitors can learn about the characteristics and capabilities of NEXRAD WSR-88D, the radar used throughout the United States. [RME]

http://www.geologyrocks.co.uk/tutorials.php

Jon Hill at the University of Edinburgh and Katie Davis at Bristol University created this website to provide numerous educational materials to geology students of all ages. Students and educators can find many tutorials in sedimentology, paleontology, geophysics, and more. The website features fifty-seven geologic-related images as well as a few puzzles. With materials covering basic to post graduate topics, all geology students can benefit by visiting this exceptional website. Although educational materials for kids are not yet available, they should be provided soon so educators should revisit this website. [RME]
