This is an activity about the Kp index, a quantification of fluctuations in the Earth's magnetic field due to the relative strength of a magnetic storm. Learners will take a reading from a magnetometer site and make a Kp index estimate to predict... (View More) whether or not an aurora display will occur near that site. This resource is designed to support student analysis of THEMIS (Time History of Events and Macroscale Interactions during Substorms) Magnetometer line-plot data. This activity requires the use of a computer with Internet access. This is activity 18 in Exploring Magnetism: Earth’s Magnetic Personality. (View Less)

This is an activity about using spectrogram plots as an indicator of magnetic activity on Earth. Learners will analyze spectrogram data and compare it to local Kp indices in an attempt to determine global magnetic storminess. This activity uses real...

This is a presentation to be used by educators to teach about the Sun and its effects on Earth's magnetosphere, including characteristics of coronal mass ejections, or CMEs, the aurora, and solar wind. A web link to a PDF or PowerPoint presentation... (View More) is supplied, along with background information for the instructor. After the presentation, learners will read about various aspects of the Sun-Earth connection and write about one aspect that they found interesting from the presentation and the printed information. Internet access is required to obtain the presentation resources. This resource is Activity 14 of the Magnetic Mysteries of the Aurora teachers guide. (View Less)

This is an activity about vectors and velocity. It outlines the addition and subtraction of vectors, and introduces the application of trigonometry to describing vectors. The resource is designed to support student analysis of THEMIS (Time History... (View More) of Events and Macroscale Interactions during Substorms) Magnetometer line-plot data. Learners will complete worksheets consisting of problem sets that allow them to work with vector data in magnetic fields. This is activity 15 from Exploring Magnetism: Earth's Magnetic Personality.
