Learners will investigate the relationship between mass, speed, velocity, and kinetic energy in order to select the best material to be used on a space suit. They will apply an engineering design test procedure to determine impact strength of... (View More) various materials. This is engineering activity 2 of 2 found in the ISS L.A.B.S. Educator Resource Guide. (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 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 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 lesson about using gravity to assist in spacecraft navigation. Learners will relate an elastic collision to the change in a satellite's or spacecraft's speed and direction resulting from a planetary fly-by, often called a "gravity assist"...

This is a lesson about the design and operation of an ion propulsion engine. Learners will study the essential components and variables of an ion propulsion system. Activities include an on-line ion propulsion engine simulation and design. Included... (View More) are changes in energy and fuel consumption as a result of variable changes (dependent/independent variable relationships). This is activity 5 of 5 in Structure and Properties of Matter: Ion Propulsion. (View Less)
