Comet Imagine a place far, far away at the very edge of the Solar System. A place where millions of comets can be seen swishing around in every direction. These icy comets are orbiting the Sun in two different places, both of which are very distant. One place is called the Oort cloud, and the other is called the Kuiper Belt.
Comet Dictionary Definition: A comet is a small world which scientists sometimes call a planetesimal. They are made out of dust and ice, kind of like a dirty snow ball.
Student Read Many people think that a comet's tail is always following behind it, but actually the coma, or tail, can either be behind the comet or in front of it. Which way the tail is pointing depends on where the Sun is. That's right, the Sun's heat and radiation produce a wind called the Solar Wind, as a comet gets close to the Sun it begins to melt. The gas and dust that melt off are blown away from the Sun by the solar winds. So if a comet is traveling towards the Sun then the tail will follow behind, but if the comet is traveling away from the Sun the tail will be in front of the comet.
Pictures of Comets
Student Read Comets are objects composed mostly of ice and dust that grow tails when they approach the sun. All comets have a nucleus, which is the hard rock/ice object. When a comet nucleus nears the sun, solar energy begins to heat the ice and vaporize it. The gas flies off the comet, sometimes violently enough to break the nucleus apart, and throws dust up with it.

Student Read Technology Moves Science Forward When Galileo looked into his elementary telescope, he became a pioneer in establishing the role that technology would play in our exploration of the universe. Today we have many tools that are used to help gain a better understanding of the space that surrounds us.
Teacher Read We have telescopes that can detect virtually every kind of radiation; from Radio waves to X-rays. You may have seen the movie Contact starring Jodie Foster, in which she is a radio astronomer working with what looks like a group of very large satellite dishes. See the technology that is around her that keeps her alive.
Watch the Next Movie Clip About the Movie Contact. Watch for future technology.
Teacher Read This Paragraph The Hubble Space Telescope has very precise instruments that allow it to look deep into space. It has allowed scientists to see the formation of new stars, objects that are over 10 billion light years away.
Student Read Those dishes are actually a group of radio telescopes at the National Radio Astronomy Observatory. Radio telescopes are used to detect radio waves, while an ultraviolet telescope detects ultraviolet waves.
Student Read In 1990, the United States launched the Hubble Space Telescope about 600 kilometers into orbit around Earth. It has instruments that allow us to determine a star's mass, composition, age, and distance. Since it lies above Earth's atmosphere, it doesn't deal with the distortions caused by Earth's atmosphere and has provided some of spectacular views of the deep universe.

Knowledge Chain Building Assignment Pass out the Box Building foldable, scissors, arms length of yarn, coloring pencils, glue stick and drywall screw. Cut out the box Write these 4 words on the box: Nebular theory, Big Bang Theory, Black Hole, Comet. Write the definition in your own words. Do not copy the definition word for word from your glossary list. Color the box with the coloring pencils. Poke a hole with the Drywall screw on each side of the box. Thread the yarn through the holes. Tie a large knot on the end of the yarn. Tape the Knowledge Chain on the ceiling of the room. Save this Knowledge Chain so we can add more boxes to it in other lessons. Don t forget which Knowledge Chain is yours.
