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
Where Am I?
In this lesson, students work together to find the latitude and longitude of various locations. Students also use latitude and longitude to help them figure out the distance between two given coordinate points.

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.
Motion in One Dimension - Grade 10
Grade 10: Motion. The physics of motion in one dimension involves studying how things move in a straight line. This is useful for learning how to describe the movement of cars along a straight road or of trains along straight railway tracks.
Lettre ou correspondance
La lettre est un « écrit que l'on adresse à quelqu'un pour lui communiquer ce qu'on ne peut ou ne veut lui dire oralement ». C'est une conversation à distance.
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
Earth's history in 4.56 meters: constructing a timeline with calculator tape
In this short activity, students make a timeline of Earth's history using calculator tape. The tape is 4.56 meters long, so that one billion years is equal to one meter. This exercise is designed to introduce students to the scale of Earth's history and help them gain a familiarity with some major events. It also teaches about scaling, the metric system, as well as the concepts of large numbers and deep time. The activity may be used in an introductory geoscience course. Learning goals, context
GEOLogic: Continental Drift and Plate Tectonics
GEOLogic questions are puzzles that were developed to support students understanding of geoscience concepts while challenging them to develop better logic and problem solving skills. In this exercise, students are asked to match up lecturers with what day and time they teach, and how many students they have in each class based on clues given from several different perspectives. In the second part of the activity, students are asked to learn more about the historic figures mentioned by doing read
GEOLogic: How Much of the State is Wet
GEOLogic questions are puzzles that were developed to support students understanding of geoscience concepts while challenging them to develop better logic and problem solving skills. In this exercise, students are asked to match up students with their home state, and their states with the area and percentage of area of surface water that they contain, as well as where each of the states rank nationally in terms of water area. Students are given clues from various perspectives to help them deduce
GEOLogic: How Well Do You Know Your National Parks and Memorials
GEOLogic questions are puzzles that were developed to support students understanding of geoscience concepts while challenging them to develop better logic and problem solving skills. Using a game show format, this exercise asks students to associate historical figures with a particular National Park or Memorial, as well as the number of points each student contestant scored on the show. This activity is appropriate for a high school science class or an introductory level undergraduate geoscience
GEOLogic: Lagerstatten and Unique Fossils
GEOLogic questions are puzzles that were developed to support students understanding of geoscience concepts while challenging them to develop better logic and problem solving skills. In this exercise, students are asked to match up several unique fossils with the sites and locations where they were found, as well as their geologic age. This activity is appropriate for a high school science class or an introductory level undergraduate geoscience course, and can be given as an in-class assignment
GEOLogic: Museums and their Dinosaur Displays
GEOLogic questions are puzzles that were developed to support students understanding of geoscience concepts while challenging them to develop better logic and problem solving skills. In this exercise, students are asked to match five top museums with two fossils that they have on display based on clues presented from various points of view. This activity is appropriate for a high school science class or an introductory level undergraduate geoscience course, and can be given as an in-class assign
Modeling the interior of the Earth using Seismic Waves
This is an inquiry-based student exercise designed to explore how we use seismic waves to understand the structure of the Earth's interior. Students test several models of the interior of the Earth beginning with a simple homogeneous Earth and moving toward more complex multi-layered Earth models. The ultimate goal involves student generation of a model that reproduces actual measured seismic travel times as closely as possible. The activity is appropriate for an introductory level geoscience co
Radioactive Decay and Geochronology
This activity was developed to introduce upper level undergraduate students to dynamical systems modeling. In this exercise, students create a STELLA model of the radioactive decay process. They then learn how the special radioactive series 238U - 206Pb and 237U - 205Pb can be used to determine both the time when a rock initially crystallized and when it underwent a recrystallization, even when the sample being dated was not a closed system. Learning goals, context for use, teaching tips, materi
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
