What is Space like?

• Space is cold, dark, and very empty.
• Scattered here and there throughout the emptiness
  are stars, planets, moons, asteroids, comets,
  meteoroids, and dust.
• People have spent years looking up at the sky and
  studying the things in space. First they looked
  with their eyes, then with telescopes.
• Today people can travel to space aboard space
  shuttles, and spacecraft to other planets and
  moons.

What do you know about Space?

• What do you see when you look up at the night
  sky?
• Do you listen to news reports about space
  missions?
• Have you ever visited a planetarium?
• Make a list of the things you know about space,
  the planets, the Moon, and the Sun.

What do you want to know?

• What other planets are made of?
• How hot is the Sun?
• How do astronauts live in space?
• Make a list of questions you have about space.

How will you find out?

• You are going to build models and do hands-on
  explorations that will help you discover answers
  to many of your questions.

Safety

• Never look directly at the Sun. You can
  permanently damage your eyes.
• Scientist Galileo Galilei went blind after
  observing the Sun with his telescope.

The Universe

• The Universe is everything that exists, including
  all matter and energy everywhere.
• By studying stars, planets, and other objects in
  the sky, you will learn where Earth is located in
  the universe.

Astronomy

• Astronomy is the study of what is beyond the
  Earth. It is the oldest science.
• As early as 2000 BC, Babylonians were using the
  sundial, the oldest known instrument for telling
  time. The shadow of the sundial correlates with
  the Suns position in the sky and hence with the
  time of day.
