Area of a triangle using the box method (Coordinate Geometry)
An interactive applet and associated web page that calculate the area of a triangle using the box method in coordinate geometry. The applet has a triangle with draggable vertices. As you drag them the triangle's bounding box is shown and the area recalculated by subtracting the areas of the outside triangles. The grid and coordinates can be turned on and off. The area calculation can be turned off to permit class exercises and then turned back on the verify the answers. The applet can be printed

Winter Field Lab: Pond Hydrology
This field activity may be implemented during late winter or early spring when things have not quite thawed. From a frozen pond, students collect bathymetric data, measure water temperature and conductivity, locate ground-water inputs, and extract a sediment core. Back in the lab, they make hand and computer-contoured bathymetric maps, temperature and conductivity cross-sections, and run visual-core log, loss-on-ignition, and magnetic susceptibility tests. Then they draw conclusions about water
Winter Field Lab: Snow Hydrology
This field activity may be implemented during late winter or early spring when things have not quite thawed. Students collect their own data from a snowpack, including measuring water equivalent, identifying types of snow metamorphism, finding evidence of precipitation patterns, and judging possible snowpack hazards. Back in the lab, students evaluate their data, draw conclusions, and make a report. This activity is designed for upper-level undergraduate and graduate-level geohydrology courses.
