Introduce the lesson by talking about the Milky Way galaxy and our solar system. Have students identify the planets in our solar system and talk about the characteristics of each planet. What makes Earth different from other planets? Discuss the various stars and other celestial bodies found in our galaxy. A good way to introduce this topic is to view segments of the Stargazing video or DVD.
After watching the program, tell students that they will pretend to be astronauts who have just returned from a journey across our galaxy. In that role, they will create journals that document what they saw in outer space. Their journals must be descriptive and creative and include at least five facts about all nine planets in our solar system; they must be descriptive and include comparative information about at least three different celestial objects (such as a black hole, asteroid, meteor, or supernova). Each journal should be a minimum of three pages in length.
Give students time in class and as homework to write their journal entries. To collect facts, students may use library references and other texts, the Astronomy program, Internet resources, or other research material. The following Web sites have information and pictures that may prove helpful to student research:
When students have finished writing their entries, have them decorate sheets of white construction paper with drawings or photographs of planets and celestial objects. Have students fold these collages in half and "bind" their journal entries inside.
Allow volunteers to read parts of their journals aloud to the class. Hold a discussion about different celestial objects in our galaxy and the similarities and differences of the planets. Display the journals in the classroom so that students can read other journals.
Definition: Of or relating to the night sky
Context: High above Earth in the night sky, a universe of stars, planets, and other celestial objects appears to revolve about us in fixed patterns.
Definition: The path described by one celestial body in its revolution about another
Context: The sun's gravity is strong enough to hold all the bodies in our solar system in orbit.
Definition: A young neutron star that produces beams of radiation from its magnetic poles
Context: A pulsar is a neutron star that sends out or beams regular pulsating waves that can be picked up on Earth.
Definition: The sun with the celestial bodies that revolve around it in its gravitational field
Context: Our solar system includes nine known planets, as well as moons, asteroids, comets, and thousands of meteors.
Definition: The death explosion of a massive star, resulting in a sharp increase in brightness followed by a gradual fading
Context: This supernova was first seen in 1987 in a galaxy near ours called the Large Magellenic Cloud.
