This is an activity about how giant dish antennas work. Learners create a "sound cone" and use it to understand how the Deep Space Network antennas pick up radio communications from space.
This guide provides instructions on how to make color pictures using images downloaded from the WISE archive. An overview of what digital images and FITS files are is followed by a discussion on the basic process of how gray scale images are... (View More) adjusted, assigned color, and added together to create a color picture. Five different image processing programs are provided to the users, along with the pros and cons of each program, and links for installing and using each one. There is also a review of the various image artifacts that may be found in WISE images. (View Less)
This interactive, web-based activity allows children to see the universe in many different wavelengths of light - light our eyes can and cannot see. To use the viewer, first select a celestial object (planet, galaxy, etc.), then select an... (View More) electromagnetic wavelength range to view it (e.g., visible, ultraviolet, infrared). Images are from various ground- and space-based telescopes. In addition, background information is provided on the electromagnetic spectrum and selected telescopes designed to detect specific regions of light. (View Less)
This Hubble Space Telescope image shows an especially photogenic group of interacting galaxies called Arp 273. The larger of the spiral galaxies, also known as UGC 1810, has a disk that is distorted into a rose-like shape by the gravitational tidal... (View More) pull of the companion galaxy below it, also known as UGC 1813. The encounter between the two galaxies also has created regions of intense star formation. In the accompanying educational activity, In Search of ... Interacting 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)
This is a game about planning what to take on a space trip to Mars. Learners will decide on the appropriateness of items to take on a long trip to Mars and take into consideration the effects of zero gravity, limited electrical power, etc.
This model aims to help illustrate the purpose and methodology of NASA's Kepler mission. It includes (1) a hand-cranked or motorized orrery (moving model of a planet system) made of LEGO parts, (2) a light sensor representing the Kepler photometer,... (View More) (3) computer software for graphing light curves, representing Kepler Science Office - data analysis. A light bulb at the center of the orrery represents a star, and as planets in the model pass between the star and the light sensor, dips in the computer graph light curve happen in real time.

This Hubble Space Telescope image shows what appears to be a delicate bubble of gas floating serenely in space. In actuality, the bubble is the visible remnant of a powerful supernova explosion called SNR 0509. The bubble was formed from gas being... (View More) swept up by the expanding shock wave. In the accompanying educational activity, In Search of ... Supernova Remnants, students investigate supernova explosions and remnants 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)
This is an activity about magnetism. In this activity, polystyrene spheres and several strong neodymium magnets are used to represent the Sun and Earth and their distinct magnetic fields. Participants construct and use a field detector to predict... (View More) where the magnetic fields are on the Sun and Earth, and use field bits, which is the term used in the lesson plan, made from the closed staples to form loops and trace the invisible magnetic fields of the Sun and Earth. The activity is designed to be used in an informal public outreach setting, for example as a stand-alone station in a family science day event. It can also be modified for use as a simple classroom demonstration. There are background information sheets provided that can be printed to go along with the activity station. This activity requires two polystyrene spheres, 8 neodymium magnets, epoxy adhesive, wire clippers, needle nose pliers, and acrylic paints, along with other easily obtained materials. (View Less)
This Hubble Space Telescope image captures thousands of sparkling young stars nestled within the star-forming nebula NGC 3603. This stellar "jewel box" is one of the most massive young star clusters in the Milky Way Galaxy. The image and text... (View More) describe a family portrait of stars in different stages of their lives, from infant stars still wrapped in cocoons of gas to stars nearing the end of their lives. In the accompanying educational activity, In Search of ... Stellar Evolution, students investigate stellar evolution 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)
This is a game about the formation of the solar system. Learners dynamically engage in modeling the growth of asteroids from specks of matter. Similar to tag, the children run around, have fun, and burn off energy. Different from tag, there is... (View More) science involved! The end of activity debriefing discusses strengths and limits of the model. Note the setting for this activity should be large and open where students can run. (View Less)
