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 is an activity about observing and mapping sunspots by direct solar observation. Learners will use a small telescope, binoculars, or a Sunspotter to create a projected image of the Sun and trace the position of any observed sunspots on a piece... (View More) of paper. Additionally, learners will mark the direction of the Sun image’s motion. This is Activity 2 of the Space Weather Forecast curriculum. (View Less)

This is an activity about measurement. Learners will label key points and features on a rectangular equal-area map and measure the distance between pairs of points in order to calculate the actual physical distance on the Sun that the point pairs... (View More) represent. This is Activity 5 of the Space Weather Forecast curriculum. (View Less)

This is an activity about coronal mass ejections. Learners will calculate the velocity and acceleration of a coronal mass ejection, or CME, based on its position in a series of images from the Large-Angle Spectrometric Coronograph (LASCO) instrument...

The NASA spacecraft missions represented by this material include SOHO, TRACE, STEREO, Hinode, and SDO. (View Less)

This is an activity about bar magnets and their invisible magnetic fields. Learners will experiment with magnets and a compass to detect and draw magnetic fields. This is Activity 1 of a larger resource, entitled Exploring the Sun. The NASA... (View More) spacecraft missions represented by this material include SOHO, TRACE, STEREO, Hinode, and SDO. (View Less)
