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

Distance from a point to a line using trigonometry
An interactive applet and associated web page that demonstrate how to find the perpendicular distance between a point and a line using trigonometry, given the coordinates of the point and the slope/intercept of the 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 grid and coordinates can be turned on and off. The distance calculation can be turned off to permit class

Optional Soil Infiltration Protocol
The purpose of this resource is to determine the rate at which water soaks into the ground. Students place two cans into the soil and add water to them to a depth of at least 5 cm. Students measure and record the time it takes the water level to drop a fixed 2 - 4 cm distance. Students repeat the measurement to determine how easily water moves vertically through the soil.

Driving Through Geologic Time - An analogy
This activity uses an analogy to illustrate the scale of geologic time and our limited view of the Earth's history. It relates the history of the Earth to a drive across the country. The drive is 4560 km (rough distance between Washington D.C. and Seattle), with 1 km equaling one million years of Earth's history. This analogy is used by the author as a springboard to talk about the limits of our personal perceptions and experiences when making conclusions. Learning goals, context for use, teachi
