Title: Asteroid Challenge, Target: Earth
Url: http://spaceclass.org/apophis/
Publisher: Space Class
Description: This interactive multimedia feature introduces students to asteroids. Topics include what they are, where they occur, and the probability that a large asteroid might strike the Earth. There is a discussion of Near-Earth Asteroids (NEAs) and particularly the asteroid Apophis, an asteroid over a thousand feet wide that is expected to pass very close to Earth in 2036. There is also discussion of possible ways to alter the orbits of NEAs so that they will not hit the Earth. After each segment, which consists of narrated videos and illustrations featuring Dr. Neil deGrasse Tyson, director of New York City's Hayden Planetarium, students complete a quiz to move on to the next section. The feature concludes with virtual labs in which students match spectrograms of asteroids with compositions of known substances such as water, carbon, and iron, and compute the trajectory of an asteroid to see if it will hit the Earth. Users may select the material in a novice (lower grade) or expert (higher grade) level.
