The purpose of the first part of this video is to introduce the idea of summation and its notation using the Greek-letter Sigma. We practice working with sums by using Gauss's summation trick. In the second part of the video, we study examples of infinite series, one which converges to a finite number (geometric series), and one which diverges (harmonic series).

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 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.
In this activity about magnetic fields and their relation to the Sun, learners will simulate sunspots by using iron filings to show magnetic fields around a bar or cow magnet, and draw the magnetic field surrounding two dipole magnets, both in parallel and perpendicular alignments. Finally, learners examine images of sunspots to relate their magnetic field drawings and observations to what is seen on the Sun.
