This is an online lesson associated with activities during Solar Week, a twice-yearly event in March and October during which classrooms are able to interact with scientists studying the Sun. This activity is scheduled to occur during Monday of... (View More) Solar Week. The lesson introduces the concept of astronomical filters and their connections to imaging different objects in space. Learners will explore perceptions of images as seen using different colors of light, construct a filter wheel, and practice investigating various astronomical images using the filter wheel. This material was designed to highlight how filters are useful to astronomers and show how a real astronomical telescope uses filters to image the Sun. Outside of Solar Week, information, activities, and resources are archived and available online at any time. (View Less)

This series of laboratory lessons and activities uses authentic solar imagery and data to introduce students to solar science. Students are asked to explore details in imagery, including how to deal with the issues of noise and resolution, and... (View More) understand scale. They are introduced to the concept of space weather and how that affects both observing instruments and the Earth. Students learn about spectra, how helium and coronium were discovered, and go on to explore real spectra from the Sun. Most activities are mathematically based, and targeted for grades 9-10. Imagery is included from NASA/ESA's SOHO mission, NASA's SDO mission, and Japan's Hinode satellite. (View Less)

This is an activity that compares the magnetic field of the Earth to the complex magnetic field of the Sun. Using images of the Earth and Sun that have magnets attached in appropriate orientations, learners will use a handheld magnetic field... (View More) detector to observe the magnetic field of the Earth and compare it to that of the Sun, especially in sunspot areas. For each group of students, this activity requires use of a handheld magnetic field detector, such as a Magnaprobe or a similar device, a bar magnet, and ten small disc magnets. (View Less)

This is an activity about image comparison. Learners will analyze and compare two sets of images of the Sun taken by instruments on the Solar Dynamics Observatory spacecraft. With Set 1, they will observe the Sun in both a highly active and a... (View More) minimally active state, and be able to detect active regions and loops on the Sun by comparing the two images. With Set 2, they will identify areas of high magnetic activity on a magnetogram image and recognize that these areas correspond to highly active regions on the Sun. (View Less)

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... (View More) 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. (View Less)

Using a set of activities, recommendations, and diagrams, participants will construct a fully functional Space Weather Action Center (SWAC) for use in a classroom. Students will access, analyze, and record NASA satellite and observatory data to... (View More) monitor the progress of an entire solar storm. Afterward, they will transform the data collected in their student journals into real SWAC news reports using an adaptable SWAC script. (View Less)

This is an activity about the period of the Sun’s rotation. Learners will select images of the Sun from the SOHO spacecraft image archive. Next, they will calculate an image scale for the selected solar images. Then, they will use it to help... (View More) determine the actual speed of sunspots based on measurements of their motion in the selected Sun images and, finally, determine the period of the Sun's rotation. This activity requires access to the internet to obtain images from the SOHO image archive. This is Activity 3 of the Space Weather Forecast curriculum. (View Less)

This is an activity about depicting the relative strength of magnetic fields using field line density. Learners will use the magnetic field line drawing of six magnetic poles created in a previous activity and identify the areas of strong, weak, and... (View More) medium magnetic intensity using the density of magnetic field lines. This is the fifth activity in the Magnetic Math booklet; this booklet can be found on the Space Math@NASA website. How to Draw Magnetic Fields - II in the Magnetic Math booklet must be completed prior to this activity. (View Less)

This is an activity about depicting magnetic polarity. Learners will observe several provided drawings of magnetic field line patterns for bar magnets in simple orientations of like and unlike polarities and carefully draw the field lines and depict... (View More) the polarities for several orientations, including an arrangement of six magnetic poles. This is the fourth activity in the Magnetic Math booklet; this booklet can be found on the Space Math@NASA website. (View Less)

In this activity, learners construct a classroom-based Space Weather Action Center and use it to obtain, analyze, and record real solar data on a weekly basis. A set of sequential activities are also provided to engage the audience in making... (View More) informed decisions about space weather using their collected data. Please note a computer with an Internet connection is required to access NASA data. This activity is part of the Space Weather Action Center Educator's Instructors Guide, which follows the 5E learning cycle. (View Less)
