The Universe Do Nows and Discussions

The Universe Do Nows and Discussions

1. What is happening as well travel through space?2. What were the force elements created?3. How is E=mc2 related to the Big Bang?4. What was discovered in Holmdel NJ?5. What is mostly likely the end to the universe?

After the Big Bang Video Discussion and Notes:

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 out2. Flat Universe- We will eventually stop expanding but again all stars will burn out3. Big Crunch or Closed- Eventually dark energy wears off and the gravity pulls back into another

Big Bang4. 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- Big Bang 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

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 articleb. Provide a summary of the articlec. State what YOU THINK is significant about the discoveryd. Draw and label you image Then we will Listen to the NPR story on this finding:e. After listening, bullet three key things you heardf. 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?

Current Events Activity:

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

The “TakeAway” Story

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 planets6. 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

Do Now: Spectra Lab1. 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

Do Now:Stellar Evolution

1. 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? Earth1. 861,000 miles in Diameter2. 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
