Ozone-good+up+high

= Ozone: Good up high =

**2) Research: What is the ozone layer? What is the chemistry behind how it's produced and how it's depleted?**

 * Use Cornell note style to write down the questions below (you may leave space below each question or write them all together and take notes underneath them. Use the resources in green to answer the questions:
 * What is ozone?
 * Where is good and bad ozone located?
 * How is ozone in the stratosphere made (include a visual of the chemistry)?
 * What are natural sources of ozone depletion?
 * What are CFCs?
 * What things do humans use that have CFCs?
 * How do CFCs break down ozone (include a visual of the chemistry)?
 * What is the Montreal Protocol? (refer to video below)
 * When was it formed?
 * Who formed it?
 * What is it's status today?


 * Go to the following site and read Part I and Part II of ozone formation. Make sure you click on the interactive animations. [|**http://sunshine.chpc.utah.edu/labs/ozone/ozone_main.html**]

=Part II: The chemistry of ozone manipulative= Using gum drops and toothpicks, create a visual chemical reaction of the breakdown of the formation AND the breakdown of ozone.
 * Come up to Ms. Byron's desk and make ball and stick models of ozone-forming reaction**

=Part III: How are students around the world affected by stratospheric ozone?=

=Part IV: Assessment=
