Learners will shape mashed potatoes into their own odd-shaped asteroids. They can then bake them in the oven to turn them (more or less) asteroid color, and eat them for dinner.

This activity is an interactive word find game with words related to comets and NASA's Comet Nucleus Sample Return mission. Accompanying text and pictures describe what comets are and why we are interested in them.

This interactive illustrates how images from space get to Earth and how we interpret the images. Users are encouraged to experiment with images to get a firm grasp of how scientists use color filters to interpret data. Click on the initial image at...

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 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 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.
