SCI.2.2 2010 - Earth and Space Science
Day to day and over the seasons, observe, measure, record and recognize
patterns and ask questions about features of weather. (2.2.1, 2.2.2, 2.2.3,
2.2.4, 2.2.5, 2.2.6) Investigate how the position of the sun and moon and the
shape of the moon change in observable patterns. (2.2.7, 2.2.8, 2.2.9)
A is for Astronaut.
An Astronaut is someone who travels space.
B is for Big Dipper.
The Big Dipper is a group of stars in the sky that

C is for Comet.
A comet is a giant ball of ice and snow that orbits
the sun. As it gets close to the sun it melts and
leaves a “tail” behind it.
D is for Day.
A “day” is the time it takes the earth to spin around
one complete time. It is also the time frame when
the sun is in the sky.
E is for Earth.
Earth is the third planet from the Sun. Earth is
where we live.
F is for Fireballs.
A fireball is a meteor that is brighter than any of the
planets.
G is for Galaxy.
A galaxy is a system of millions of stars and
planets. Earth is in a galaxy called The Milky Way.
H is for Hubble Space

J is for Jupiter.
Jupiter is the fifth planet from the Sun. It is the
largest planet.
K is for Kepler.
Johannes Kepler was a German Astronomer. He
figured out how the planets move around the Sun.
We call that Planetary Motion.
L is for Light-Year.
A light-year is a unit of astronomical distance equal
to the distance that light travels in one year.
M is for Moon.
A moon is planet-like, but it is not a planet. A moon
rotates around a planet. Earth only has one moon
while some planets have several.
N is for Neil Armstrong.
Neil Armstrong was the first man on the moon. He

Our solar system has eight planets. Mercury,
Venus, Earth, Mars, Jupiter, Saturn, Uranus, and
Neptune are the planets.
Q is for Quasar.
Quasars are the brightest objects in the universe.
They are so far way that we cannot see them just
by looking into the sky.
R is for Rocket.
A rocket is a very powerful engine. NASA uses
rockets to send satellites and spaceships into
space.
S is for Stars.
Stars are made of gas and plasma. They are really
bright because they explode. Our closest star is the
Sun. No one knows how many stars actually exists.
T is for Telescope.
A telescope is a tool astronomers use to see distant
objects, like stars and planets, bigger and more
clear.
U is for Universe.
The Universe is everything. It includes the stars, the
planets, the moons, and the galaxies. The Universe
is really big. It is everything.
V is for Venus.

close to the Sun.
W is for West.
West is the direction that the Sun and stars set.
There are four directions North, South, East, and
West.
X is for eXplore.
We eXplore space to learn more about our solar
system and where we live. There are many space
eXplorers.
Y is for Year.
A year is the length of time it takes Earth to orbit the
Sun. A year is usually 365 days.
Z is for Zodiac.
The Zodiac is a circle of star constellations that the Sun passes through
during a year of time. There are twelve constellations in the Zodiac. They
