Title of Unit:** The Chemistry of Fireworks

Essential Question:** "I've Seen Fire and I've Seen Rain"... but, how can it rain fire?
 * Three Questions:

What do electrons have to do with fireworks?
 * Unit Question:**

Where are electrons located? What is an electron configuration? What is the electron configuration of an atom at its ground energy state? What is the electron configuration of an ion? Which elements have similar electron configurations? How does Group and Period affect electron configuration? How are electrons excited? What happens when an electron is excited? What happens when an excited electron returns to its ground state? What wavelength is emitted when an electron in a hydrogen atom moves from n=X to n=Y? How is light emitted by the fireworks? What makes the different colors in fireworks? What is a "ground state" electron configuration? What does it mean for an electron to be excited? How does an electron become excited? What happens when an electron becomes "un-excited"?
