Learners will take and then compare the images taken by a camera - to learn about focal length (and its effects on field of view), resolution, and ultimately how cameras take close-up pictures of far away objects. Finally, they will apply this... (View More) knowledge to the images of comet Tempel 1 taken by two different spacecraft with three different cameras, in this case Deep Impact and those expected/obtained from Stardust-NExT. This lesson could easily be adapted for use with images from other NASA missions. (View Less)

This is an online sorting game that compares the lifetime risk of death from an asteroid impact to other threats. For example, are you more likely to be killed by an amusement park ride or an asteroid impact? It is part of the Killer Asteroids Web... (View More) Site. The site also features a background overview of the differences between asteroids and comets, information on different types of asteroids (rubble piles vs monoliths), a discussion of how at risk Earth really is to an asteroid or comet impact, and background information on light curves.

This is a multi-level, physics-based game that asks players to save Earth by using their spaceship to deflect an incoming asteroid. It is designed to accurately reflect the physics of space and could be used to help confront preconceptions about... (View More) motion and forces in space.

This is a game about light curves that will test your ability to figure out things about an asteroid from just a graph of its brightness. Astronomers use telescopes to collect light curves - measurements of the brightness of distant asteroids over... (View More) time. It is part of the Killer Asteroids Web Site.

This is a game which focuses on the challenge of moving a "rubble pile" asteroid. Players have the option of using bombs, impactors, or "pusher" ships. It is a simpler version of Rubble! and part of the Killer Asteroids Web Site. The site also...

This is a website about asteroids and comets. Learners can play a physics-based asteroid game, learn about how backyard astronomers are contributing to asteroid research, or simulate an asteroid impact using a Google Earth Impact simulation....

This online game allows players to choose any location on Earth and impact it with a variety of different sized asteroids and comets. They can see how big the blast radius will be, and determine what size object it would take to wipe out their town.... (View More) It is part of the Killer Asteroids Web Site.

This online activity introduces the importance of meteorites to the understanding of the origin of the Solar System. Learners will use a key to determine if samples are meteorites. Finding meteorites can be difficult because most meteorites look... (View More) like Earth rocks to the casual or untrained eye. (View Less)
