Arrangement of the Universe
List the major elements of the universe in order from smaller to larger:
_____________ _____________ _____________ _____________
What is the force that causes these objects to be grouped together in space? _____________
Earth: What is the size of the earth, relative to the moon? _____________
Solar System: The sun is just one of billions of _____________ in space. Astronomers have
detected other _____________ orbiting some of these stars.
Milky Way: Our solar system and the stars you can see with your bare eye are part of the
_____________ _____________ _____________. The Milky Way has billions of stars in it.
Most of the stars are so far away they appear to us as a _____________ _____________ of
light.
Universe: The Milky Way Galaxy is just one of _____________ _____________ of galaxies
in the universe. These galaxies extend in all _____________.
Constellations
What do scientists use to help determine locations, or a map, of the sky? ____________ .
Constellations are not real objects, but really just pictures or patterns of stars in the night sky
that people use to mark a location. Name two examples of constellations in the sky that you are
familiar with? ____________________________ _________________________

Extra: What zodiac sign are you? Find the constellation for your sign and draw it in the
box.
One very important star that helps in finding direction and location is a star called
_____________, also called the _____________ _____________. This star appears to stay
in the same place in the night sky, and the other stars seem to move around it.
Movements of Planets and other objects visible from Earth
The farther away a moving object is the _____________ it appears to be moving. Stars are
always moving, but because they are so far way you cannot see their movements.
By contrast, the _____________ moves across the night sky background quickly. That is
because the moon is _____________ to the earth, relative to the stars.
Where does the word “planet” come from?

Section and Video Summary
Galileo started it all with his hand-held telescope. It was powerful enough to see some of
Jupiter’s moons and show that the Earth isn’t the center of the universe. Space exploration has
mushroomed in the past 50 years. Rockets that originally lofted weapons during World War II
were converted to carry satellites, then astronauts. But more has been learned from unmanned
probes and telescopes than from manned missions. The Hubble Space Telescope is a perfect
case in point. With Hubble, we’ve been able to “see” billions of light years into space. And the
view is amazing. It makes us wonder if we’re alone in the universe. Future missions to Mars may
reveal whether life once existed on the Red Planet. If extreme-living bacteria on Earth are any
indication, there may well be proof of ancient Martian microbes. The workhorses of NASA, the
space shuttles, have launched probes and taken astronauts to service Hubble and kept our
knowledge growing.
Discussion Questions

to space?

WORM Topic Space Science 1.1
Last week we began discussing the major objects in the universe and relative sizes of
these objects. Use the information that you remember from your reading and notes
to answer the following. No books/notes are to be used.
A.
What are the basic structures in which objects are grouped together in space, in order from
smallest to largest? Write the terms in order on the lines.
B.
1. WRITE each term in a different box.
2. Connect one box with another box by drawing a line in between the two.
3. On the line, explain the relationship between two words. How are the two words connected
in meaning? Use complete sentences.
4. Make a total of four connections.
