Earth Structure: A virtual journey to the center of the earth
This lesson discusses the interior structure of the earth as defined by research on the behavior of seismic waves as they move through the layers inside of the planet. The lesson details both ...
Mantle Convection Moving Plates
This demonstration models the manner in which the convection currents in the mantle of the Earth cause movement of the plates. Convection currents in the mantle were thought, for many years, to be ...
Solid Mantle in Full Flow: The DIY Potty Putty Simulation
This demonstration illustrates the properties of the mantle of the Earth, using potty putty mixed with a solution of borax and simple glue. When left on the desk the potty putty will sink and spread. ...
The Earth's Internal Heat Energy and Interior Structure
This resource identifies the sources of the Earth's internal heat energy as extraterrestrial impacts, gravitational contraction of the Earth's interior, and the radioactive decay of unstable ...
Thermal Convection and Viscosity of a Fluid
In this activity, students construct a model that will allow them to experiment with thermal convection, illustrating how thermal energy can generate a flowing motion in a fluid. The thermal ...
Explorations in Earth Science: Three-D Earth Structure Model
In this activity, students use modeling clay or baker's clay to construct a 3-D model of the interior of the Earth to help visualize the main spherical layers or regions (the inner core, outer core, ...
Explorations in Earth Science: Journey to the Center of the Earth
This virtual journey to the center of the Earth introduces the traveler to the structure, material properties and conditions within the Earth's interior. The size and scale of the Earth and of its ...
Earth Structure and Changes (title provided or enhanced by cataloger)
In the first of these two modeling activities, students make a model and label the layers of the interior of the Earth including the inner and outer cores, the mantle and the crust. In the second ...
Journey to the Center of the Earth
This 1 hour 36 minute radio broadcast discusses the first direct evidence that the inner core of the Earth is spinning faster than its crust. Guest host Richard Harris talks with researchers about ...
Deep Mantle Plumes Help Explain Hawaii's Origins
This radio broadcast discusses a theory that says the Hawaiian Islands formed as a result of deep mantle plumes. The theory of plate tectonics does not explain their origin, since they are in the ...
Scientist Proposes Alternative to Deep Mantle Plumes
This radio broadcast continues the discussion from the previous show ('Deep Mantle Plumes Help Explain Hawaii's Origins') over whether the Hawaiian Islands were created by deep mantle plumes. Don ...
Magnetic Reversals: Fact and Fiction
In this activity students learn about Earth's magnetic reversals by reading two fiction stories and a scientific summary of past reversals, including graphical information. This will help students ...
Earth's Inconstant Magnetic Field
This article discusses our planet's magnetic field, which is in a constant state of change. The location of the North Pole has been moving north at an average speed of 10 km per year, lately ...
New Type of Deeper, Longer Quake Discovered
This radio broadcast reports on the discovery of a new kind of earthquake that is much deeper and longer lasting than other kinds of quakes. These long, super-deep tremors originate at a depth of ...
Hotspots: Mantle Thermal Plumes
This article discusses the idea of 'hot spot' volcanoes, those not associated with plate tectonic boundaries, but rather with relatively stationary sources of heat energy (thermal plumes) in the ...
An Introduction to Geomagnetism
This tutorial introduces students to geomagnetism, the Earth's magnetic field, and its changes through time and space. Topics include the properties of Earth's magnetic field, how it makes a compass ...
