This site offers several sets of questions for students to answer about where mountain ranges are located and why they are where they are. Many of the questions have links to more information and/or images. Questions address the role of plate tectonics in the process of mountain building. A computer isn't necessary to answer the questions, but is highly recommended so that the students can use the ... Full description.

This series of exercises demonstrates basic principles associated with the Earth's magnetic field. Several relevant questions are included to support conceptual learning. Full description.

This site describes bouyancy (the difference between the upward and downward forces acting on the bottom and the top of an object) and the Archimedes Principle, which states that the buoyant force on a submerged object is equal to the weight of the fluid that is displaced by it. It consists of text descriptions of these principles, using the examples of metal cubes suspended in water and hot air baloons ... Full description.

This review material is meant to reinforce student understanding of the relationship between plate tectonics and the rock cycle. Although developed for students in the United Kingdom, it can easily be modified for any region on Earth. The activity involves students answering questions based on their knowledge of plate tectonics and the rock cycle and could be used as a homework assignment or individual ... Full description.

This homework exercise asks undergraduate geology students at Tulane University to view the National Landslide Hazards Map, published online by the U.S. Geological Survey, and determine what geologic features are present that contribute to high incidence or susceptibility to landslides. Students are also asked to read online articles, and answer questions about the costs of landslides in terms of ... Full description.

These Virtual Voyages were created as one-hour homework assignments for a freshman-level oceanography course at San Francisco State University (SFSU). Each voyage is structured around real-world images and includes five multiple-choice questions and five short-answer questions. Topics include seafloor bathymetry west of San Francisco, Earthquakes, Hawaiian hot spot, ocean waves, tides in San Francisco ... Full description.

This site demonstrates how, with the use of orbital mechanics, a space mission to Mars can be planned. Using no more than algebra, Kepler's laws and the formula for the energy of an object in a Kepler orbit, it derives the time for an optimal flight to Mars, the timing of the flight, the thrust needed to enter the orbit and to leave it upon arrival, and details of the flight back to Earth, including ...

This website offers arithmatic practice, games, geometry lessons, graphing, algebra and even trigonometry and calculus. The problems and quizzes provide instant feedback. There are also sections for parents and teachers with educational tips and ideas. Full description.

This homework exercise, developed for an undergraduate geology course at Tulane University, leads students through the steps involved in determining the probability that a flood of a given discharge will occur in any given year. Students retrieve discharge data from U.S. Geological Services Internet sites for Dry Creek, LA, Rapid Creek, SD and Red River, ND to make their calculations. Full description.

This educational game reviews concepts learned during an astronomy or space science unit. It can be adapted to any material and any curriculum. The game serves as a motivational tool to enhance enjoyment of reviewing concepts. The site includes instructions for the game and sample questions about the Earth, the sun, other planets, and constellations along with some questions called potpourri. Full description.
