Plasma and the Plasmasphere

Exploring the Plasmasphere [PDF] Students use an image of the plasmasphere obtained by the IMAGE satellite to calculate how fast it orbits the Earth. They will use this to determine whether gravity or Earth's magnetic field provides the forces responsible for its movement through space.

Exploring the Plasmasphere [PDF] Students learn that the Pythagorean Theorem is more than a geometric concept. Scientists use a photograph taken by the IMAGE satellite to measure the size of Earth's plasmasphere region using a ruler and protractor.

Radio Plasma Imaging with IMAGE [PDF] Students use the Distance = Velocity x Time relationship to determine the distances to plasma clouds seen by the IMAGE satellite.

Plasma Clouds [PDF] Students use a simple 'square-root' relationship to learn how scientists with the IMAGE satellite measure the density of clouds of plasma in space.
