Put these events in the correct order
1) Creation of elements: At the core of the star, heavier “stuff” is
created, including carbon and iron.
2) Gases are pulled together by gravity into clouds called Nebulas.
3) The singularity: All matter is crammed into a tiny point the size
of a proton.
4) Protostars are formed: a dense cloud of gas surrounded by a
spinning disk.
5) Supernova: As center of star gets heavier, it explodes
dramatically.
6) Universe expands rapidly: Universe cools off, matter is created.
THE SOLAR SYSTEM
Essential Question: What orbits
the Sun and why?
The sun is a star in the center of our solar
system
Gravity is a force that holds the objects of our
solar system in orbit
Earth, its moon, and the sun form a system
within our solar system
The planets were created from a nebula that
formed after a supernova
A SYSTEM is a set of parts
that come together to work
as a whole
Example: Solar System
The SOLAR SYSTEM is the sun and
all the objects that move around it
*Other objects that orbit or move
around the sun are planets,
comets, meteors, and
asteroids

Planets form from a nebula that is created from a
Supernova. Unlike the nebula that created the original star,
this planetary nebula contain heavy “stuff” that can turn
into planet.

the inner and outer planets?

Today’s objective
•Earth, its moon, and the sun form
a system within our solar system
•Rotation causes day and night
•Revolution causes seasons
THE MOON
A natural satellite that orbits around planets.
The
the
is star, made up of gases, found in
of the solar system
***The sun is the nearest star to earth
 The sun is the main source of light in the
solar system
The sun can be compared to a heat lamp
 We are able to see the moon at night
because it reflects the sun’s light

Rotation and
Revolution of
the Earth
ROTATION
Rotation is the spinning of an
object about its axis
The earth rotates
about its axis in a
counter-clockwise
direction
The earth makes
one complete
rotation in 24 hours
The earth is tilted at
an angel of 24.5o
Rotation of the earth on its axis causes day and
night
REVOLUTION OF THE EARTH
The Revolution of the earth around the sun
produces the seasons: summer, winter, spring and
autumn/fall
The earth complete one revolution in
365 days or 1 year
Gravity from the sun helps to keep the planets in
orbit or moving around it
Rotation of the earth on its axis and
the Revolution of the earth around
the sun occur at the same time

TODAY’S VOCABULARY
ORBIT- The path an object takes as it travels around another object
REVOLUTION -The movement or orbit of an object around another object.
ROTATION -The spinning of an object about its axis
SOLAR SYSTEM -The sun and all the objects that move around it
SYSTEM- A set of parts that come together to work as a whole
INNER PLANETS- Mercury-Venus-Earth-Mars
OUTER PLANETS- Jupiter-Saturn-Uranus-Neptune
GRAVITY- The force that pulls objects towards each other
SATELLITE- An object that moves or revolves around a planet
SUNSPOT- A part of the sun that is very magnetic and is not as hot as other
parts
Asteroids are
objects in the solar
system that are
smaller than
planets but bigger
than meteoroids.
A comet is a
relatively small
objects in the
solar system,
made of dirty
ice, that orbits
or moves
around the sun
***Usually in the
outer solar
system
Meteoroids are small, particle-sized objects in the
solar system that are usually seen as “shooting stars”
or “falling stars”
