In this teacher’s magnetism activity guide, “Exploring Magnetism,” students are given the opportunity to act as scientists discovering magnetic fields and electromagnetism through inquiry and measurement.

Included at the beginning of each session is a summary of the session, a list of national education standards that the session covers, and a list of materials required for the session. Each session is broken into several activities, with each activity outlined for the teacher. In the Background Material section, you can find science background for the lessons. A glossary can be found after the background section, and at the very end we recommend different resources finding materials to purchase and for learning more about magnetism.

The activities in this guide are meant as primers for supplementary guides that allow students to learn about the importance of magnetic fields in space science, which are studied by NASA scientists. For example, in Exploring Magnetism in the Solar Wind, students learn about the stream of charged particles emanating from the Sun—called the Solar Wind— and how NASA scientists are designing a mission called STEREO to study it and its magnetic field. The other guides, Exploring Magnetism in Solar Flares and Exploring Magnetism in the Aurorae, allow students to learn about magnetism in the Sun-Earth System with more hands-on lessons.

In this 2013 interview, Dr. Ernie Hildner reflects on his extensive career in solar physics, which includes serving as the Chief of the Solar Physics branch at NASA’s Marshall Space Flight Center and spending 19 years as the Director of NOAA’s Space Environment Center (now the Space Weather Prediction Center). He discusses the scientific discoveries, technological advancements, and administrative milestones that transformed space weather from a niche research area into a vital operational service.
Dr. Hildner’s early research focused on solar prominences, but his involvement as an experiment scientist on the Skylab coronagraph in the 1970s was a major turning point. By using a disk to block the sun’s direct light (creating an artificial eclipse in space), the Skylab team was the first to directly observe and verify Coronal Mass Ejections (CMEs). Skylab’s X-ray telescopes also revealed “coronal holes” for the first time. Hildner describes these as areas where the sun’s magnetic field lines open straight out into space (comparing it to the “part in your hair”). Instead of trapping the hot solar atmosphere, these open fields act like “fire hoses,” rapidly streaming material into space and causing geomagnetic storms on Earth days later. Prior to Skylab, NOAA’s daily solar flare and storm predictions were highly crude. Skylab’s well-funded operations led to a worldwide network of observatories that monitored the Sun in real time, drastically improving space weather forecasting and fundamentally shifting NASA’s culture regarding mission planning. Hildner highlights that space weather becomes crucial for astronaut safety. While Earth’s magnetic field protects low-earth orbit, lunar and future Mars missions require deep understanding of solar radiation hazards. He names several technological and scientific milestones. He also stresses that organizing the scientific community was just as important as the research itself. Dr. Hildner concludes by emphasizing the mutually beneficial, tight-knit relationship between NASA (research and data tracking), the NSF (funding and research), and NOAA (daily operations and forecasting), which ultimately provides tangible, protective benefits to society and taxpayers.

Show | Grades 6-12+ | In this December 2012 interview, Dr. David Hathaway, a solar astronomer at NASA’s Marshall Space Flight Center, discusses his career trajectory into solar physics and outlines what he considers the most significant historical milestones in space weather research. Dr. Hathaway initially wanted to study stellar structure, evolution, and stellar interiors. During graduate school, he realized the difficulty of modeling convective heat transport in stars. Guided by mentors, he recognized that our Sun — a “star in our backyard” — offered the perfect, observable model for stellar convection. His specific focus on space weather began when his supervisor, Dr. John Davis, challenged him to predict the Sunspot cycle. Hathaway developed successful prediction methods and, because of his knack for public speaking, frequently interacted with reporters. This required him to deeply educate himself on the historical and technological impacts of space weather.

Earth has four seasons: spring, summer, fall, and winter. Other planets can experience seasons, too, but they might be wildly different from the ones that we are used to. This article explores the relationship between stars and the seasons experienced by the planets which orbit them, and is connected to educational resources that help K-12+ teachers explain seasonal changes and related concepts in simple, engaging ways for students.
