This article explains the monthly variations in the Moon's appearance as seen from Earth. Directions for using Oreo cookies to illustrate the four major phases of the Moon are provided. The article is targeted to children ages 10-12.
This article discusses the differences between ozone in the stratosphere and troposphere, and how NASA is measuring ozone using a spectrometer on-board the Aura satellite. The article includes an activity: building a spectroscope using a DVD cover... (View More) and inexpensive materials. (View Less)
The front of this poster is a cartoon profile of the atmosphere, showing the "good and bad" roles of ozone in the stratosphere, high troposphere, mid-troposphere, and surface. On the back is an article for students, beginning with an explanation of... (View More) ozone's roles, and an introduction to spectroscopy. Also includes detailed instructions for building a classroom spectroscope using a CD or a DVD as a diffraction grating. See related resources to download a PDF file that is a pattern for making the spectroscope body out of construction paper. (View Less)
This article discusses how Global Positioning System (GPS) satellites work, and how the TOPEX and Jason-1 satellites use GPS data in making very precise topological maps of the oceans. The article includes an activity. Students are divided into two... (View More) groups. One group will use triangulation to record the positions of several objects placed in a room. Using measurements from this first group, the second group will try to determine the exact placement of the objects in the first room and recreate the pattern in the second room. (View Less)
This article discusses how the Multi-angle Imaging SpectroRadiometer (MISR) instrument found on the Terra satellite is used to understand how particles in the atmosphere interact with sunlight and how particle pollution affects Earth's climate.... (View More) Directions for building a demonstration model of MISR out of cardboard tubes is included, along with short activities to show how it's multiple viewing angles allow MISR to differentiate the kinds of particles in the air because they scatter light differently, depending on their size, shape, and composition.
