HS-ESS1-2

SCUSD NGSS Curriculum Guide
 * HS-ESS1-2: Construct an explanation of the Big Bang theory based on astronomical evidence of light spectra, motion of distant galaxies, and composition of matter in the universe. ** [Clarification Statement: Emphasis is on the astronomical evidence of the red shift of light from galaxies as an indication that the universe is currently expanding, the cosmic microwave background as the remnant radiation from the Big Bang, and the observed composition of ordinary matter of the universe, primarily found in stars and interstellar gases (from the spectra of electromagnetic radiation from stars), which matches that predicted by the Big Bang theory (3/4 hydrogen and 1/4 helium).]

**Science Background for the Teacher:** Understanding the Big Bang Theory and light spectra.
====**Key Vocabulary: **Big Bang Theory, light spectra, red shift, cosmic background radiation, interstellar, electromagnetic ====



====**Possible Assessments (formative and/or summative): **====

**Key Student Activity**:
1. Research based project of finding evidence for Big Bang Theory. 2. Check out a unit with activities about the universe: (http://www.cfa.harvard.edu/seuforum/download/CQEdGuide.pdf) 3. Check out Exploring the Big Bang Theory Activity: (http://ims.ode.state.oh.us/ODE/IMS/Lessons/Web_Content/CSC_LP_S01_BA_L09_I02_01.pdf)

**Common Student Misconceptions: **
We are the center of the universe because everything is rushing away from us.

**Things to Avoid/Correct: **
Avoid trying to explain what happened before Big Bang, because nobody knows.
