Transcript Study Guide Power Point Big Bang

a.I
can describe the big bang
theory and the evidence that
supports this theory.
b. I can describe the nebular
theory of solar system formation
and the evidence supporting it.
 c.
I can explain that the heavy
elements found on Earth are formed in
stars.
d. I can explain how the accepted
ideas about the nature of the universe
have changed throughout history.
e. I can provide an example of how
technology has helped scientists
investigate the universe.

Describe how light supports the Big Bang
Theory.
 Light
is used as and evidence for the
expanding universe. Spectrums from
stars will shift closer to the red when
moving away and towards the blue
when moving toward us. We can tell
this because the spectrum lines are
visible.
Describe what Red Shift is and draw an
example of a spectrum Red shifted.
Red
shift is when an object is
moving away from us its unique
spectrum shifts towards the red
end of visible light.
Which stars would have the greatest red
shift? Those closer to us or those farther
away explain.
The
stars that are father away
from us have the greatest red shift
typically. Red shift also depends
on the speed at which the star is
traveling away from us.
Why would a firework be a good model
of the Big Bang describe the relationship
 The
theory of the big bang starts with
heat that continues to become hotter
until a large explosion. This could be
represented by a firework first the
fuse is lit the heat is present until it
reaches the explosives where it
exploded like the big Bang.
Why do scientist accept the theory?
Scientist
accept the Big Bang
theory because evidence supports
the conclusions that have been
made. The Big Bang Theory is the
best explanation for the evidence
that we have on the formation of
the universe.
What elements were formed in the Big
Bang?
The
first elements to be
formed after the Big Bang were
Hydrogen and Helium Which
are the Building blocks of every
element.
What are the 3 evidences of the Big Bang
Theory?
 The
Three Evidences are
 Red shift of spectral light
 Cosmic Background Radiation
(radiation left over from a large
explosion)
 Heavy Elements being form on Stars.
What is a Nebula?
A
cloud of Dust and Gas.
Nebulas are formed from
old stars that have
exploded in a supernova.
We have direct observation
of stars collapsing and
forming nebulea
Describe the Nebular Theory and how Solar
Systems are formed.
 Nebulae spin which creates gravitational
forces particle start to attach to one
another and they continue to become
bigger and bigger until they become the
size of a star that creates its own gravity.
Planets and other objects such as
meteorites found in the solar system are
formed in a nebula and are held in place
by the gravity of the star.
Why are meteorites the same age and
composed of the same material as our Earth?
Meteorites
are Created in the
same nebulae that have made the
planets they surround. Thus they
are made from the same material
and have the same age as the
plants they are around.
Where did the heavy elements that make up
our Earth come from?
As
stars go through their life
cycle, nuclear fusion happens.
As the elements start to fuse
heavier and heavier elements
are created. This is part of star
evolution.
What happens to atoms of a star each time it
goes through a life cycle?
Atoms
continue to fuse
elements and the atoms
become heavier and heavier
as more protons are added in
the creation of elements.
Supernova’s produce what kind of elements
in the universe?
Supernova’s
are the largest stars
and the longest living stars. These
stars are the stars that produce
the heaviest elements known to
man.
Why did people believe that the earth was the
center of the Solar System? And why was Galileo
sent to jail for his ideas of the sun being the center
of the Solar system?
 Observation
with their own eyes told them the
sun when up on one side of the earth and
down on the other. If the Earth was spinning
they thought they would be falling off it. With
their knowledge and ability to gather
information it was the explanation that made
sense to them. Galileo went to jail because,
his ideas opposed the cultural and religious
practices of his time.

How has technology increased our knowledge
of the Universe?
 Through
telescopes such as Hubble,
which helps us collect accurate data
from space. We have microwave
receivers, We have discovered the
background radiation left over from
the big bang.
What is Cosmic Background Radiation and
how does it support the Big Bang Theory?
Cosmic
background Radiation is
the ‘afterglow’ of the big bang, a
microwave radiation which still
uniformly permeates all of space.
It is considered one of the best
evidences for the Big Bang Theory.
What does much of the Big Bang Theory
depend on?
Much
of the Big Bang theory
depends on our understanding
of the Data that has been
collected as evidence. This
Data has been collected
through technology
