Universe Size and Scale -- Know Your Galactic Address
On the board Comprehending the size of the universe is incredibly difficult. This project will help you understand the vastness of space Gloop Glork, a friend in a distant galaxy wants to send you a letter about her trip to a black hole. A regular address has only three or four lines. Due to the great distance, the address has to be specific so the letter can get to you. PROCEDURE:

The universe is weird, expanding, and explained by the Big Bang Theory
Students took guided notes on the Big Bang Theory.
Strong lines of evidence include:

A new set of breathtaking photos reveals a never-before-seen deep view of the universe.
Released as the first "Frontier Fields" view from NASA's Hubble Space Telescope, the new images mark the deepest-ever observations of a cluster of galaxies. The photos center on Abell 2744, a group of several hundred galaxies 3.5 billion light-years away from Earth.
The images also capture background galaxies more than 12 billion light-years away, whose light has been magnified and brightened by the immense gravity of Abell 2744 in a phenomenon known as gravitational lensing, researchers said.

Timeline of the Universe

Something you should try- http://www.johnkyrk.com/evolution.html. It’s a timeline from the big bang up to the Protozoic Era. The animations are eye catching, and it’s a breeze to use. Loading times may be slow due to all of the different pictures you’ll see, but it’s well worth it. Credit goes to John Kyrk.

- Content: Explore the evolution and life cycle of medium and large mass stars.
- Language Purpose: Use scientific vocabulary terms such as stellar, protostar, nebula, black hole, red giant, supernova, and white dwarf.
- Outcome: Work with shoulder partner to create a graphic organizer, differentiating the life cycles of medium mass and large mass stars.

Stars can be arranged according to their luminosity and temperature on a diagram. The current age and evolutionary state of a particular star can be determined by using this diagram.
Activity sheet contains two activities:
|
InteractiveWe have animated the HR diagram to help you understand how a star changes throughout its life. In this animation, a star will move throughout the diagram. DO NOT BE DECEIVED! The star does not physically zip around the universe as it ages. The star physically stays in the same location, but the movement is to show how luminosity (brightness) and surface temperature change with star age. Remember, it’s a diagram, not a star map.
Stars and Personality? Is astrology a science or pseudoscience?We read and discussed a Relatively Interesting article on astrology.
Students predicted what the world would be like if astrology were What would the world be like if it did work?
Do horoscopes really all just say the same thing? 22,000 horoscopes were analyzed with an online tool called TagCrowd to find the most common words. The data we used to create a meta-chart or graphic. Analysis revealed that the bulk of the words in horoscopes (at least 90%) were actually the same. In fact the most common words could be combined to write a generic prediction.
Challenge Question: What are some characteristics indicating something may be pseudoscience? Stars Presentation
Nuclear Fusion
What would happen if the sun explodes?
Common student question: What would happen if the sun exploded?
The good news is that our Sun will never explode (even though more massive stars can and do). The Sun is big for a star, but just isn't massive enough to fuse anything past helium in its core. More massive stars can continue nuclear fusion until they make the element iron. This creates an unstable core which will then explode in a supernova explosion. So what would happen if our sun did somehow manage to explode? Go to this link and read this article.
