Title: Earth, Moon, and Beyond


1
Earth, Moon, and Beyond
2
Day and Night
  • The sun is the star at the center of our solar
    system. It gives off energy.
  • The cycle of day and night occurs because Earth
    rotates, or spins on its axis.
  • Earths axis is an imaginary line that passes
    through the North and South Poles.
  • 24 hour cycle

3
Earths Seasons
  • Earth revolves or travels in a path around the
    sun. This path is called Earths orbit.
  • Seasons are produced by Earths tilt on its axis.
  • Earth is divided into 2 hemispheres by the
    equator which is an imaginary line.
  • When it is summer in the Northern Hemisphere it
    is winter in the Southern Hemisphere.

4
Revolves vs. Rotates
  • Earth REVOLVES around the sun in a year.
  • Earth ROTATES on its axis in a 24 hour day.

5
High and Lows
  • Seasons at the North and South Pole are very
    different from other places.
  • In the summer the poles get 6 months of daylight
    and no darkness. In winter there are 6 months of
    darkness and no daylight.
  • The South Pole has vey low temperatures all year
    long.

6
The Moon
  • Any natural body that revolves around a planet.
  • Rocky
  • Made up of aluminum, oxygen, calcium, silicon,
    and iron.
  • Contains craters which are bowl shaped areas on
    the surface.
  • No atmosphere or water.

7
Moons
  • Moons orbit planets, not the sun.

Phases of the Moon
  • The moon travels around the Earth.
  • The moon rotates as it revolves.
  • The moon rotates slower than the Earth.
  • The moon does not give off its own light.
  • As the moon orbits the Earth its position in the
    sky changes.
  • A moon phase is one of the shapes the moon seems
    to have as it orbits Earth.
  • The cycle takes 29 ½ days.
  • The side of the moon we can not see from Earth
    was once called the dark side of the moon. This
    is incorrect because all sides of the moon
    receives light.

10
Eclipses
  • Occurs when one body in space blocks light from
    reaching another body.
  • On Earth, we see solar and lunar eclipses.
  • A solar eclipse occurs when a new moon casts a
    shadow on Earth.
  • A lunar eclipse occurs when a full moon passes
    through the shadow of Earth.

Phases of the Moon
13
The Sun and Other Stars
  • The sun is a star which is a huge ball of hot
    gases in space.
  • The sun is the center of our solar system.
  • A solar system is made up of a star and planets
    and objects that revolve around that star.
  • The sun is important because of the energy it
    provides.
  • Scientists classify stars by color and
    brightness.
  • A constellation is a pattern of stars.

14
stars
  • Constellations appear to shift across the sky
    nightly. But it is earth that moves.
  • Different stars can be seen in different seasons.

15
Stars
  • Stars can be smaller, larger, brighter, farther
    away, closer.
  • Sun is the brightest because it is the closest to
    Earth.
  • Differ in size, brightness, appearance, in
    relation to distance.
  • They emit energy.

16
Inner Planets
  • A planet is a body that revolves around a star.
  • The four inner planets are Mercury, Venus, Earth,
    and Mars.
  • They are rocky and dense.
  • Mercury is closet planet to the sun.
  • The asteroid belt between Mars and Jupiter.

17
What is a planet?
  • Large object in space that revolves in space
    around a sun on its own orbit.

18
Venus
  • Surrounded by thick clouds.

19
Outer Planets
  • There are 5 outer planets Jupiter, Saturn,
    Uranus, Neptune, and Pluto.
  • The first four are gas giants (made mostly of
    hydrogen and helium) and Pluto is now considered
    a dwarf planet.
  • Jupiter is the largest planet.
  • There is a new dwarf planet Eris also called UB
    313.

20
Our Solar System
21
Beyond the Solar System
  • The universe is everything that exists which
    includes the stars, planets, dust, and energy.
  • A galaxy is gas, dust, and a group of stars.
  • Galaxies are classified by shapes.(irregular,
    elliptical, spiral, barred spiral)

22
Space Exploration
  • The telescope allows people to get a closer look
    at space.
  • Today scientists use telescopes, satellites, and
    space probes to explore space.

23
  • Space probe is a spaceship that investigates and
    transmits details to earth.

24
Lesson 3
  • There are different types of galaxies.
  • Scientists classify them by their shape.

25
Colors of Stars
  • Characteristic that determines the color of a
    star is the temperature.

26
Suns Size
  • The sun is a medium sized star, but it looks
    larger because it is closer to earth than others.

Questions
  • What makes up a galaxy?
  • What is the name of our galaxy?
  • How does Earths Orbit affect the seasons?
  • What is the difference between rotate and revolve
    when referring to Earth?
  • How does the Earth and the moon compare?

32
QUESTIONS
  • What makes up our solar system?
  • How are the movement of the sun, moon, and stars
    connected?
  • How do starts differ?
  • If you were to survive on the moon, what supplies
    would you need?
