To Do	To Answer
Read about the Big Bang	What are some possible ends to the universe? What determines each possible end? Describe Cosmic Background Radiation and why it is important. Describe inflation and why it is important. Describe dark energy and why it is important.
Examine the infographic	What has occured since the Big Bang? How long ago was the Big Bang? How old was the universe when the first stars appeared?
Watch the video	What were the first particles to form? What role does energy play in the beginning of the universe? When were protons and neutrons formed? What were the first elements to form? How old was the universe when this happened? What caused the universe to be transparent and dark? What eventually formed at the densest locations? How did the first heavy elements form? How did heavier elements get dispersed throughout the universe? Create a timeline of the universe, based on the contents of this video.
