In this activity, learners replicate the scientific processes of observing, forming an explanation, revising and communicating about a model of a comet. Learners construct a model of features of a comet using an assortment of common craft supplies.... (View More) This activity relates to several NASA comet missions such as Deep Impact, Stardust, Stardust-NExT, and EPOXI and can be used to emulate a process that scientists and engineers follow on all missions.

This website has gathered images taken at different wavelengths by a variety of ground-based and space-borne observatories, including selected astronomical objects in the famous Messier catalog, as well as for some non-Messier objects. An online... (View More) gallery introduces the wealth of data available at wavelengths beyond the familiar visible light. Users will discover some important characteristics of astronomical phenomena, and learn about which types of radiation are best suited for studying certain objects. The Gallery features a mosaic of various images, each taken at a different wavelength. By scrolling down through the Gallery, you will find copies of each image, accompanied by explanatory text which will explain the similarities and differences between images. (View Less)
This manual provides simple demonstrations to show how lenses and mirrors are used to create telescopes. It was created for use by the Night Sky Network of astronomy clubs.
This poster series highlights six astronomical images observed with NASA's Great Observatories (Hubble, Chandra and Spitzer) and found within the "From Earth to the Universe" (FETTU) exhibition. Each poster contains additional information on the... (View More) historical context of the astronomical objects (constellation, view with the unaided eye), as well as basic facts about the specific object, the category of object, the NASA missions used, and the contributions to advancing knowledge of the universe enabled by the NASA observations. The materials expand on the theme of demonstrating how far understanding and knowledge have come since Galileo's telescope 400 years ago with illustrations of specific NASA contributions, provide background information on which informal educators can draw for NASA-related activities in their programming, and include student activities.

This Hubble Space Telescope image of galaxies appears to form the number 10. The text describes the image and provides a brief explanation of why astronomer Halton Arp compiled his catalogue of odd-looking galaxies in the 1960s. In the accompanying... (View More) educational activity, In Search of ... Peculiar Galaxies, students investigate galaxy interactions through a level 1 inquiry activity using the images and text from the lithograph and other resources. A level 1 inquiry activity can help prepare students to become independent thinkers. (View Less)
The main scientific instrument on the Gamma-ray Large Area Space Telescope (GLAST) is the Large Area Telescope (LAT). This interactive computer-based educational activity allows students and web users to see the results when gamma-ray photons of... (View More) different energies and incident angles hit the LAT. The photons convert into electron-positron pairs which travel through 19 interleaved layers of silicon into the cesium-iodide calorimeter. Background information about the mission and the LAT is also provided. Note: In 2008, GLAST was renamed Fermi, for the physicist Enrico Fermi. (View Less)
This is a lesson about the shape of objects in space. Learners will observe the surface of rotating potatoes to help them understand how astronomers use variations in reflective brightness to determine the shape of asteroids.
These short videos introduce learners to the electromagnetic spectrum though eight animations including an introduction to electromagnetic waves and one animation for each wavelength of the EM spectrum (Radio, Microwave, Infrared, Visible,... (View More) Ultraviolet, X-Rays and Gamma Rays). Each wavelength of the EM spectrum offers a construct to illustrate and teach about NASA sensors, missions, and science. Emphasis is placed on relevant science (e.g., lunar exploration) and hot science topics (e.g., climate change). Each video is computer animated and offers engaging illustrations to appeal to middle and high school age learners. The examples and narrative for each wavelength animation build on the learners’ prior knowledge then introduces examples from NASA missions. These examples explore the use of spectral analysis and visualizations that help scientists make discoveries about the world around us using EM waves. (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... (View More) on NASA's Solar and Heliospheric Observatory (SOHO) spacecraft. This is Activity 2 of a larger resource, Exploring the Sun. The NASA spacecraft missions represented by this material include SOHO, TRACE, STEREO, Hinode, and SDO. (View Less)
