  1. The Geomaths MathHelp material - University College London (UCL)
    Part of the Interactive Mathematics and Geoscience Education (IMAGE) project, Geomaths MathHelp provides mathematics self-study material embedded within the geological sciences. MathHelp "notebooks" cover specific mathematical topics accessed through a relevant geological context; for example, power functions through seismic velocities, trigonometry through cliff erosion, and integration through sediment accumulation. The notebooks contain explanations, illustrations, examples and practice quizzes (online, for registered students). Modules are organized into revision, 1st level (corresponding roughly to pre-A level and A-level standard), and 2nd level (for students of Geological Sciences who have A level mathematics or equivalent) respectively. A mathematical glossary is also constantly available. more>>

  2. U.S. Geological Survey - U.S. Department of the Interior
    Scientific fact-finding and research organization of the U.S. Dept. of the Interior; the principal source of scientific and technical expertise in the earth sciences within the U.S. Federal Government. Includes The Learning Web, where Teacher Developed Lessons for Biology, Geology, Hydrology, and Geography include math such as kids measuring the population density of local insects and comparing their own data to Amazon data; or tracking developments in the malformation and decline of amphibian populations in North America and elsewhere. more>>
