Sc. 10 _Unit4: Part 1_Big Bang Theory

Learning Objectives

The big bang theory can be used to explain the formation of the universe from a singularity composed of pure energy.  As the universe aged, expanded and cooled, that energy was transformed to matter leading to the formation of nuclei, atoms and eventually stars, planets and life.

    • big bang theory

    • components of the universe over time

    • astronomical data and collection methods

At the end of this Section you should be able to:

  • Define Big Bang theory and explain its relationship to the expansion of the universe.

  • Describe what occurred after the Big Bang.

  • Describe evidence scientists have discovered to support Big Bang theory.

Guiding Question: How did everything begin in the Big Bang? 

  • If the universe is expanding, the next logical thought is that in the past it had to have been smaller. A point even.

  • The time when the universe began is the explosion known as the Big Bang.
