This is an activity about image resolution. Learners will recreate a solar image taken by the Solar Dynamics Observatory (SDO) using various sizes of building bricks, and discuss how their recreations relate to image resolution. Learners will also... (View More) compare SDO images to solar images from older spacecraft to see how improved technology helps scientists learn more about the Sun. (View Less)
This is an online Flash-based interactive tool kit that provides access to illustrations, visualizations, videos, and near-real time images of the Sun from a variety of NASA spacecraft missions. Learners can access this information to supplement... (View More) other materials related to the Sun and heliophysics. (View Less)
In this self-guided lesson, students read and learn about the history of Earth imaging and the Landsat satellite. They develop interpretation skills as they play a game that involves inferring the subjects of various Landsat images.
Maps and images are examined, compared and contrasted in this introductory lesson. Beginning with the school building map typically posted in their classroom, students analyze the information it contains, describe its features, and determine its... (View More) purpose. Students then examine maps at different scales to compare and contrast the amount of detail and the purposes. Maps are then compared to NASA satellite images. The use of satellite images to measure and map land usage is explored through images of Las Vegas taken in 1972 and 1992 (note: see Related & Supplemental Resources for link to more current images). The URL opens to the investigation Directory, with links to teacher and student materials, lesson extensions, resources, teaching tips, and assessment strategies. Note that this is investigation two of four found in the Grades K-4 Module 1 of Mission Geography. The Mission Geography curriculum integrates data and images from NASA missions with the National Geography Standards. Each of the four investigations in Module 1, while related, can be done independently. (View Less)
This is an activity about sampling specifically in astronomy. Learners will make a sampling window in order to estimate the number of stars in the sky visible to the unaided eye. After, they will discuss how to estimate the effect of different... (View More) variables on their counts, such as sky brightness, dark adaptation, cloud cover, etc. Please note use of a clear night sky is optimal for this activity. (View Less)
