Teams continue with the Asteroid Impact challenge and determine possible locations to construct their underground shelters. Participants cut scale area models of their shelters from paper and place them on the map to find locations...

Teams must determine the size of cavern needed to house the citizens of Alabraska to protect them from the asteroid impact. Using scaling properties, teams first determining the number of people that could sleep in a classroom and then...

Space scientists use water displacement to determine the mass of a cubic centimeter mini meteorite, and then use it as a small-scale representative of an asteroid. They figure out the orbital velocity of an asteroid. Then they use a...

For this asteroid and comet worksheet, students read about the formula used to determine the brightness of asteroid. They apply this formula to solve 2 problems about asteroids and their brightness.

Students role-play and communicate that objects in space have describable properties, locations, and movements. Students identify and communicate effectively that Earth is the third planet from the Sun in the solar system, eight other...

Article reports on a new study that claims that the energy released from asteroid collisions may have sparked life on Earth. Includes a list of key vocabulary.

Explains the differences between asteroids and comets. Presents a chart showing a size comparison between some known asteroids and comets.

Asteroids can be single large rocks, or they can be collections of rocks loosely bound by their mutual gravity "rubble piles." The difference is important to understand, so we know how to deal with these if they head towards Earth. A...

"The survivals and extinctions at the close of the Cretaceous are such as might be expected to result from intensely hot winds such as would be generated by extra large meteoritic impacts." This article suggests that this theory should...

This site from the SkyServer allows you tolearn all about moving objects as well as how to find asteroids. Users that feel adventurous may even decide to take the "Asteroid Hunt."
