The Coordinate Plane
An interactive applet and associated web page that describe the concept of the coordinate plane (Cartesian Plane). The applet shows the plane, its axes, origin and related controls. The user can drag a point around and see the coordinates change, and click anywhere to create new points. The origin can be dragged to emphasize or eliminate certain quadrants. The grid, axis pointers and coordinates can be turned on and off. The coordinate display can be turned off to permit class exercises and then

Coordinates of a point
An interactive applet and associated web page that describe the concept of a point in coordinate geometry. The applet show one point initially, but clicking anywhere adds more. As the points are dragged, the coordinates are seen to change. The grid, axis pointers and coordinates can be turned on and off. The coordinate display can be turned off to permit class exercises and then turned back on the verify the answers. The applet can be printed as it appears on the screen to make handouts. The web

Distance from a point to a line
An interactive applet and associated web page that demonstrate how to find the perpendicular distance between a point and a line. The applet has a line with sliders that adjust its slope and intercept, and a draggable point. As the line is altered or the point dragged, the distance is recalculated. The page actually shows four ways to do it, with links to detail pages on each one. The grid and coordinates can be turned on and off. The distance calculation can be turned off to permit class exerci

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.

Toilet Paper Analogy for Geologic Time
This in-class demonstration involves using a 1000 sheet roll of strong toilet paper to demonstrate the vast length of time involved in Deep Time. Important events in geologic history are marked on the toilet paper. As the toilet paper is unrolled, from the front of the room to the back and around the room, students begin to get a sense of how little time humanity has been on Earth and how much time is really involved.
