This short (11:29 minutes) video features NASA scientists answering a set of student-designed questions related to NASA’s Global Precipitation Measurement satellite mission. The set of twelve questions were generated after students viewed... (View More) animations of GPM data; the questions centered on satellite operations, satellite data, and precipitation patterns and impacts. (View Less)
This is an online game 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. Outside of Solar Week, information, activities, and... (View More) resources are archived and available online at any time. This is a scavenger hunt game to allow learners to review science concepts covered in previous activities. This game is scheduled to occur during Tuesday of Solar Week. (View Less)
This two-sided poster presents images and information about ozone. The front features a series of color Earth images; each image reflects total ozone readings taken every October from 1979 to 2012. The poster back contains information about ozone... (View More) under the following headings: What is Ozone?, Chemistry of the Ozone Layer, Measuring Ozone in the Earth's Atmosphere, Timeline of Stratospheric Ozone Depletion and Observations, How the Ozone Hole Forms, and A World Avoided. In addition, the back contains two activities: Visualizing the Ozone Hole and a Color by Number worksheet. (View Less)
This is a poster about radiation in space. Learners can read about the Van Allen belts and how NASA's Van Allen Probes are investigating the influence of the Sun's energy on Earth. The activity version also includes math problems, a vocabulary... (View More) matching game, a communication research challenge, and a toolbox of web resources. (View Less)
This is a legacy site for videos and animations related to the Deep Impact mission and encounter with Tempel 1. Learners can watch videos about the mission, encounter, science, and results.
In this online interactive, learners will explore how scientists learn about the composition of an asteroid by studying energy and neutrons that emanate from it. Includes audio (and transcription) explaining the diagram.
This tutorial lays the foundation to participate in the Students' Cloud Observations Online (S'COOL) project. S'COOL engages students in making and reporting ground truth observations of clouds then comparing those observations with data from the... (View More) CERES satellite instrument. Student observations are taken within +/- 15 minutes of the satellite overpass schedule; scientists then use those observations to validate and improve the satellite results. The tutorial covers the following four topics: determining satellite overpass time, observing cloud properties, transmitting results to NASA, and comparing results with satellite-retrieved properties.

This activity models grazing incidence reflection by using students as the “sea of electrons” provided generally by metallic bonding on the surface of a metal. A tossed ball is used to represent a photon of light and the ball tosser represents... (View More) the object giving off the photon. This activity is designed to illustrate that different photons may be absorbed or reflected, depending upon their energy to illustrate how the telescope utilizes grazing optics to focus X-rays.The activity requires balls of various sizes (ping pong ball, golf ball, tennis ball, basketball or bowling ball). The activity guide includes discussion questions and instructions for using the video "Building the Coolest X-ray Satellite: Astro-E2" in the classroom. (View Less)
This lithograph shows an image of Mars on the front, with informational text on the back about how the Hubble Space Telescope (HST) has been used to study Mars weather. HST took this image on March 30, 1997, just as it was making a close pass to... (View More) Earth some 60 million miles (100 million km) away. It shows Mars during the transition between spring and summer in the northern hemisphere (summer solstice). The north polar carbon dioxide (dry ice) frost cap is rapidly evaporating from solid to gas, revealing a much smaller permanent water ice cap. Bright water ice clouds are visible across the center and along the bottom of the image. (View Less)
This chapter provides background information to teachers about remote sensing. Topics include the electromagnetic spectrum, sensors and platforms, scale and resolution, geographic information systems, and ground truthing images. The reading is... (View More) appropriate as well for high school students. The primer is part of the Ground Truth Studies Teacher Handbook, which provides more than 20 activities to build student understanding of global change and remote sensing, and includes background chapters for teachers, glossary, and appendices.
