4 Revolution (noun) root word = revolve  Definition: To move in a curved path around a central object, such as a star or planet.  Sentence: The Earth revolves around the sun. It makes one revolution every days (1 year).

5 What is the difference between the words “rotate” and “revolve?”  Rotate means ___________, but revolve means_________.

6 Use these words: rotation, axis, revolution The earth rotates on its central point, or ________. It makes one full ____________ on its axis every 24 hours and one ______________ around the sun every days.

7 Orbit (noun or verb)  Definition: The curved path of an object around a central object in space.  Sentence: (noun) The comet might cross the earth’s orbit.  Sentence: (verb) The planet Mercury orbits the sun. “Orbit” is a thing “Orbit” is an action

8 What’s the difference between “revolve” and “orbit?” THINK PAIR SHARE

9 Satellite (noun)  Definition: A natural object that orbits around another object in space.  Sentence: The earth is a satellite of the sun.

10 The earth is a satellite of the sun. The sun is a satellite of the earth. The earth orbits the sun. We put a satellite into orbit. Are these statements correct? Why or why not? THINK…. THEN SHOW!

11 Solar System (noun)  Definition: A system of planets or other bodies orbiting another star.  Sentence: There are eight planets in our solar system.

12 Galaxy (noun)  Definition: Group of billions of stars and their planets, within the universe.  Sentence: Our solar system is located in the Milky Way galaxy.

13 Universe (noun)  Definition: All matter and energy, including galaxies, solar systems, and all of the contents of space.  Sentence : Scientists love to explore the universe to learn new things about deep space.

14 Which is bigger?  A solar system ?  A galaxy ?  The universe ?

15 Star (noun)  Definition: A sphere of hot glowing gases that releases energy in the form of heat and light.  Sentence: When the sky is clear, you can see many stars. They look like this! Not like this!

16 Planet (noun)  Definition: A massive, spherical (circular) space object that orbits a star.  Sentence: Two planets in our solar system are called Mercury and Venus.

17 Comet (noun)  Definition: A mass of frozen gas, cosmic dust, ice crystals, and organic material that orbits the sun.  Sentence: The light of a passing comet is exciting to watch.

18 Asteroid (noun)  Definition: A mostly rocky object that orbits the sun.  Sentence: Many people want to know what would happen if a large asteroid hit the earth.

19 Meteoroid (noun)  Definition: A solid object moving in space that is smaller than an asteroid.  Sentence: A meteoroid that comes near earth usually breaks up in the atmosphere.

20 Comparison Matrix Orbits the Sun A solid object Mostly made of ice or gas Mostly made of rock Comet Asteroid Meteoroid Put an “x” in the correct box

21 Using the correct word Meteoroid A solid object moving in space, smaller than an asteroid Meteor The streak of light that is produced when a meteoroid burns as it enters the atmosphere Meteorite A meteroid that strikes a planet

22 Meteoroid? Meteor? Meteorite?  If you saw a flash of light go across the sky, like a shooting star, it would most likely be a _________.  If you found a rock in the desert that came from space, it might be a ___________.  If you saw an object space that looked smaller than an asteroid, it may be a __________.  If you see something burning up in the atmosphere, it could be a ____________.
