Outcome B Sun notes
EQ- What are the parts of the sun?
BELL RINGER- WHAT ARE THE
SIMILARITIES AND DIFFERENCES
BETWEEN EARTH AND VENUS?
ANSWER: EARTH VS. VENUS
Similarities
Size
Differences
Venus rotates very slowly from east to west; Earth
rotates more quickly from west to east
Density
Venus has a thick atmosphere that is mostly
carbon dioxide; Earth’s atmosphere is mostly
nitrogen and carbon dioxide
Internal structure
Venus is much hotter than Earth; Earth has liquid
water on most of its surface

These are the answers you are looking for.
1. What are the layers of the sun?
2. How does the sun make energy?
3. What are the parts to an atom?
4. What is a sunspot?
THE SUN
A star
 Provides light and
heat to Earth
 Made of hydrogen
and helium
 About 4.6 billion
years old

PARTS REVIEWED




When you see an image of the
sun, you are seeing the
photosphere
The sun’s corona, which looks
like a halo, can usually be
seen only during a solar
eclipse
The middle layer of the sun’s
atmosphere is the
chromosphere
Sunspots are darker areas of
gas on the sun that are cooler
than the surrounding gases
LABELING THE SUN
When you get you sun worksheet put your
name on it.
 We will label together

CREATE A SUN
Your table will work together to create a sun
with all it’s parts on the white boards.
 I will walk around and quiz you on the different
parts.

least 10. Use this has a review of your planet

CHEMISTRY BACKGROUND INFORMATION:
An atom is the
smallest particle of
an element
 Atoms have a core,
or nucleus,
containing neutrons
(no charge) and
protons (+ charge)
 Electrons (- charge)
surround the
nucleus

Nucleus: has
neutrons and
protons
Electrons
surround
ATOMS




Atoms can have a positive,
negative, or neutral charge
Atoms can change their
charge by gaining or losing
electrons
When an atom gains an
electron, it becomes a
negative ion (an ion is an
atom with an unequal amount
of protons and neutrons)

THE PERIODIC TABLE:
 Lists
all of the
elements
 The atomic
number is the
same number
of protons in
the nucleus of
an atom
WHAT CAUSES THE SUN TO PRODUCE ENERGY?

Nuclear fusion- the
combination of the
nuclei of small atoms to
form a larger nucleus;
releases energy



Atoms are very active
and crash into each
other
The nuclei become
joined, releasing huge
amounts of energy
Nuclear fusion occurs in
the core, or center, of the
sun

Smallest terrestrial
planet
VENUS





Known as the “morning
star” and “evening star”
Earth’s twin due to size
and density
Retrograde rotation
meaning that it rotates
opposite of Earth
Pressure is 90 times
greater than on Earth
Atmosphere traps heat
from the sun causing a
“greenhouse effect”
EARTH

One of the conditions
required for life on Earth
is liquid water

Similarities

Venus rotates very slowly from east to west; Earth
rotates more quickly from west to east

nitrogen and carbon dioxide
Internal structure
Venus is much hotter than Earth; Earth has liquid
water on most of its surface
MARS



May have had conditions
needed to support life
because there is evidence
that liquid water was once
present
Spirit and Opportunity
rovers found clear
geologic evidence of
ancient streams, lakes, or
floods
Ice is present at the polar
ice caps



Large amount of water
exists as a gas in the
atmosphere
Because the atmosphere is
too thin, water cannot exist
as a liquid
Atmosphere is mostly
carbon dioxide
ASTEROID BELT


Located between Mars
and Jupiter
Too small to be
considered planets
OUTER PLANETS:




“Gas Giants”
Composed mainly of hydrogen and helium
Atmospheres of the gas giants cannot escape
into space because they have very strong
gravitational pulls
Jupiter, Saturn, Uranus, Neptune
JUPITER


Largest and most
massive planet
“Great Red Spot” is a
huge storm
SATURN


Rings are mostly made
up of chunks of ice and
rock
Only planet that has a
lower density than water
URANUS

Different from most
other planets because it
rotates on its side
NEPTUNE


Astronomers predicted
the existence and orbit
of Neptune based on
Neptune’s gravitational
effect on the orbit of
Uranus
Very similar in size and
color to Uranus
