Students construct a model of a comet nucleus using dry ice. They add other materials and describe the features. They complete related exercises on an Internet Web site.

Students study the environmental concerns of orbital debris.  In this orbital debris  lesson students complete several activities.

Middle schoolers investigate how engineers navigate satellites in orbit around the Earth and on their way to other planets in the solar system. They study vocabulary words and participate in studying a satellite by learning about times...

Young scholars, viewing an Internet site, plot the path of several satellites using latitude and longitude over the course of an hour. They learn the four basic types of satellites and their purpose.

Students model how meteors fall to the surface of planets. In this space science lesson, students identify different types of meteorites using an interactive online website. They investigate the relationship between a meteorite's size...

Students fill in a diagram of a comet. They listen to a short lecture, view flash animation descriptions of comets and meteors and then use the presented information to complete a worksheet.
