Plate Tectonics
In this activity students use various large-scale data sets (earthquakes, volcanoes, bathymetry, etc.) to follow the evidence in building the theory of plate tectonics. Learn more
Plate Tectonics (Magnetic Field)
Magnetic stripes on the seafloor was the elusive evidence that solidified Plate Tectonics as a valid scientific concept. Student use the magnetic field sensor and small magnets to reproduce this evidence. Learn more
Plate Tectonics
See the evidence for plate tectonics and the way plate movement affects our Earth.
Earthquakes and Volcanoes clearly mark the boundaries of tectonic plates. What else can we tell from earthquakes? Let your students do the investigating. Enlarge image.
Summary:
In this activity, students will be observing several different types of data in order to expose them to the evidence that supports the theory of plate tectonics developed by Alfred Wegener.
Students will use their critical thinking skills to create and support a theory that corroborates the concept of plate tectonics, as well as continental drift, using the provided data as evidence for plate movement.
Students will also explore fossil and glacier deposits, elevation and bathymetry, sea floor age, earthquakes, and volcanoes as evidence of plate tectonics.

Here's what you need:
My World GIS is a Geographic Information System (GIS) designed by educators specifically for learning with a GIS--not about a GIS. It is a powerful mapping and analytical tool that provides visual representation of data in a geographic context.

Plate Tectonics - (Magnetic Field)
Students investigate natural magnetism in mineral magnetite and in turn, learn how natural magnetism was used as evidence for plate tectonics.
Notice the "symmetry" about the center of the graph. How does this compare to the sea floor? Enlarge graph.
Lab Summary:
In this activity students will gain an understanding of the mechanism of plate tectonics and sea floor spreading.
Students will first investigate the magnetism of rocks and minerals as well as a bar magnet. Then they will construct a model ocean floor using a shoe box and magnets, and measure the "bands" with the magnetic field sensor.
