What is happening as well travel through space?
What were the force elements created?
How is E=mc2 related to the Big Bang?
What was discovered in Holmdel NJ?
What is mostly likely the end to the universe?
1. When did the Big Bang happen?
1. 13.7 Billion years ago
2. What are TWO pieces of evidence that show us that the Big Bang happened?
1. Redshift- what is redshift????
2. Background Radiation- ???
3. How does Hubble’s law support the Big Bang Theory?
1. That the further away an object is the faster it is moving away
4. What are the four Theories that could happen in the future to our Universe?
1. Open Universe- keep expanding finitely and eventually all stars burn out
2. Flat Universe- We will eventually stop expanding but again all stars will burn out
3. Big Crunch or Closed- Eventually dark energy wears off and the gravity pulls back into another
Big Bang
4. Big Rip- the density of dark matter/energy will “rip” the universe apart
5. What was recently found in our Universe to support the Big Bang? What was
is this discovery so significant?
1. The oldest and most furthest galaxy in our universe, creating within 400,000 of the initial Big
Bang. What does this galaxy look like right now?
2. Gravitational Waves!
Do Now: Origin and Evolution of the Universe Lab
1. How do we know if a galaxy is redshifting?
2. What are the types of radiation demonstrated in the magnetic
spectrum?
3. What is the relationship between the size of the wave of radiation
and its level of danger?
The smaller, the more intense meaning the more the
radiation can travel through and hence more dangerous
Current Events Activity:
I would LOVE to share with you this AMAZING discovery that was found on
Monday, HOWEVER, do to my lack of the ability to speak, YOU WILL HAVE TO
TELL ME!
Directions:
1. Evaluate the image that has been placed on your table.
2. Next, EACH group member will read and HIGHLIGHT the same article
that has been designated for each table.
3. Then, working as a group, students will complete the white data table on
their article and image.
a. Select 10 important highlighted statements from the article
b. Provide a summary of the article
c. State what YOU THINK is significant about the discovery
d. Draw and label you image
Then we will Listen to the NPR story on this finding:
a. After listening, bullet three key things you heard
b. Lastly, if time permits, look at the other images of the classroom and using their
photos, the NPR Story and what you read, WRITE THE BIG Picture. What did they
find and will this impact our future?
What was the observation that was made on
Monday March 17th 2014 that was described as:
(Hint: This has to do with the question I asked you on Monday about
finding the very first galaxy in the universe)- THIS IS HUGE!
 “A landmark discovery that would change the face of cosmology
and particle physics”
 Was another thing discovered that Einstein previously predicted
 “Its as close to proof (of the Big Bang) that you are going to get”
 “A MAJOR MAJOR discovery”
 And will most likely win the Noble Prize in Physics
Less than a second after the Big Bang

The “TakeAway” Story
360 View of Milky Way
1. What is the relationship demonstrated in the H-R Diagram?
Positive- as temperature increases, brightness increases
2. How is the relationship with temperature and volume different? Why?
Negative- as volume increases, temperature decreases (the heat
become more spread-out)
3. Where was the Sun located in this graph?
The Central path of the graph, called the Main Sequence which means
the Sun is a very normal star
4. What is nuclear fusion?
The combining of hydrogen atoms to create helium atoms in the core of a
star that releases an enormous amount of heat and energy.
5. As a star ages, its burns heavier elements like calcium, carbon and iron. How is
this important to the formation of solar systems?
These heavier elements are what can make-up earth-like planets
6. How do you BELIEVE our solar system was formed?
A supernova of a massive star erupted about 4.6bya. The HEAVIER
elements left behind became our planets
1. What is the visible spectrum and what does it look like?
2. What are some common elements in the Universe?
hydrogen, helium, lithium, calcium, iron, sodium
3. What is spectra and what can we learn from spectra?
It is the fingerprint of an element (every element has a different way that its
spectral lines arrange them
4. What is aurora borealis? Why is it those colors?
oxygen
nitrogen

What is becoming the best types of star to examine for life and why?
1. Red dwarf- Goldilocks zone due to small size and low temperature
2. What is the size of the Milky Way?
1. 100,000 lightyears across, 28 lightyears from the Sun (Orion Arm)
3. What is an AU?
1. Distance from Earth to Sun- 90-93 million miles (why a range)
4. What is the size of the Sun? Earth
1. 861,000 miles in Diameter
2. 8,000 miles in diameter
5. What is the name of the Milky Way’s cluster?
1. Virgo
6. How many stars are in the Milky Way?
1. 216 Billion
