ESCI A.S1.O1.A8 Big Bang Assessment

What you should be able to do at this point:

• Describe the big bang theory and the evidence that supports this theory (e.g., cosmic background radiation, abundance of elements, distance/redshift relation for galaxies).
• Explain that heavy elements found on Earth are formed in stars.

If you don't feel clear about any given topic, go back and watch/read the information again or discuss it with your instructor.

For this assignment you need to write an essay with the following paragraphs. Refer back to the questions on the previous pages to get an idea of what type of information you should include. This must be in your own words or you will not receive any credit.

2. Explain what redshift is and how it supports the Big Bang Theory.
3. Explain what the Cosmic Microwave Background is and how it supports the Big Bang Theory.
4. Explain how the percentage heavy elements tells us that the universe is aging and how it supports the Big Bang Theory.
