Students learn of the impending asteroid impact scenario, form teams and begin to study the situation in depth. A simple in-class simulation shows them the potential for destruction and disaster. They complete worksheets and look at maps...

This activity poses the question: What would happen if a meteor or comet impacted Earth? Students simulate an impact in a container of sand using various-sized rocks, all while measuring, recording and graphing results and conclusions....

This comprehensive page discusses the Asteroid Impact vs. Volcano-Greenhouse dinosaur extinction debate. It was written by paleontologist, professor, and scientist Dr. Dewey McLean.

Scientists continue to learn from their observations long after the largest collision in history was recorded. Was Comet SL-9 actually an asteroid? What were the dark impact clouds made of? What were the effects on Jupiter's magnetic field?

Students build model caverns and bury them in a tray of sand. They test the models by dropping balls onto them to simulate an asteroid hitting the Earth. By molding papier-mache or clay around balloons (to form domes), or around small...

Use marbles to discover how comets and asteroids make impact craters. This hands-on experiment is easy to do and gives you many variations to try. Included are links to additional information.

Students teams determine the size of the caverns necessary to house the population of the state of Alabraska from the impending asteroid impact. They measure their classroom to determine area and volume, determine how many people the...

Students use their knowledge of scales and areas to determine the best locations in Alabraska for the underground caverns. They cut out rectangular paper pieces to represent caverns to scale with the maps and place the cut-outs on the...

Using a variety of science topics, these projects link your class with classes around the world in data collection and analysis. There are projects recommended for all grade levels. Begin dates and end dates are listed to help in...

Contains a small set of images of solar system objects and a series of links to information about all solar system objects. Solar System Tours link to excellent image collections.

"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...

A well-indexed collection of NASA images taken by the Galileo spacecraft. Images include the spacecraft itself prior to launch and all of the solar system objects this incredible mission has visited.

This is a list of links to online resources related to the study of the planets. It has a literary theme associated with the Lewis Carrol poem "The Hunting of the Snark" with many quotes from literature and science. Navigation tools...
