In this lesson students learn to recognize the types of tephra, which include a variety of ejected volcanic products, and that the distribution and type of tephra can be used to locate an eruption source and describe the style of an eruption. Students also learn that tephra is classified by size, texture, and composition and as a result of this lesson will be able to identify and describe the origin ... Full description.

This demonstration uses a gyroscope (a bicycle wheel works well), string, and a turntable (optional) to show how the equatorial bulge of Earth causes precession. By balancing the spinning bicycle wheel on one hand, and pulling a string attached to the top axle with the other, the axis of the wheel traces out a circle (precesses). The site also explains how the moment of inertia is related to torque ... Full description.

This lesson on the cause of currents and water circulation in the Arctic Ocean will require students to investigate the influence of salinity and temperature on the density of seawater to determine what factors drive water circulation in the Arctic Ocean. Students identify the primary driving forces for ocean currents and infer the type of water circulation to be expected in the Arctic Ocean, given ... Full description.

In this activity students plot the latitude and longitude involved in the movement of the Magnetic North Pole over a period of time, predict its location by the year 2000, and justify their reasoning. Students will discover that the Magnetic North Pole has been charted over the past several hundred years and that the pole shifts an average of 15 kilometers/year. They will also learn tha navigation ... Full description.

In this activity students use web-based archival and real-time data to explore how auroras change with time. They discover that during the 1990's, the National Aeronautics and Space Administration (NASA) placed research satellites in orbit around the Earth to keep the polar regions under almost constant surveillance for signs of auroral activity and that this data helps scientists explore the connections ...

In this activity, students will gain an understanding of how geologists determine rates of sea floor spreading between two tectonic plates. Using a strip map of the North Atlantic seafloor, they will measure distances and note the ages of the strips of seafloor basalt. They will also gain experience applying some basic, useful mathematical concepts such as the calculation and use of velocities and ... Full description.

This unit is designed to acquaint students with the properties of magnetic fields. It is meant to introduce the idea of a "field" through investigations of magnetic fields as produced by various common magnetic materials and direct electrical currents. They will learn that the difference between a magnetic field and a gravitational field is that a gravitational field, in the experience of a student, ... Full description.

Students use wood blocks and model boats to investigate how the shape of an object determines the friction it encounters as it is drawn through a towing tank. They learn the advantages of streamlining and increased waterline length and observe that the shape of an object affects its stability. Students are also introduced to the terms power, turbulence, hydrodynamics, work, and boat design, and explore ... Full description.
