Comets are also known as dirty snowballs or icy mud balls. With your super scientists, create a model comet nucleus to discover how they are made and take part in a scientific discussion to learn how it behaves.

Here is an interactive book instructional activity through which learners explore the facts and stories about comets. The plan is comprehensive, providing background information, standards met, vocabulary, assessment ideas, and more....

Students examine the make-up of comets and asteroids. In this comets and asteroids lesson, students examine pictures of comets in asteroids that are included in a teacher presented PowerPoint. They complete an associated worksheet.

Students study comets and how Halley's comet was created.  In this space lesson students create their own comets using dry ice.    

Students create paper comet models. They discuss facts about comets and build a model to determine the way the sun affects a comet. They create a comet and label the head and tail portions. They discuss their comet model and share it...

Young scholars explore the nature and composition of a comet. They research comet facts, legends, and myths. They identify different types of comets and describe what happens to a comet as it travels closer to the Sun.

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.

Learners examine the different types of asteroids and how they enter the atmosphere.  In this space lesson students use mashed potatoes to create an asteroid they can eat.

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 identify the different types of meteorite using an interactive website. In this earth science lesson, students simulate how meteors crash on a surface. They relate meteor size to crater size.
