What Is In Our Air?

10/26 and 10/27

To Do… Fill in 2-column notes on the right hand side with your table partners (10 min)

Try to find some “Connection to Air” for each chemistry topic that we covered.

Predict what is in the air…Grab an “Air Quality” worksheet from the side counter if you don’t have one

yet and make sure it’s complete to start class…

Whoops-A-Daisy Forms…

Where did the term “Whoops-a-Daisy” come from? Where did the term come from? Terms such as "up-a-daisy" dates to the

early 1700s, as an encouragement to a child who has fallen to stand up, or as an exclamation upon lifting a child. It's basically a nonsense phrase, presumably intended to amuse the little ones. Variants include "upsi-daisy" or "upsy-daisy" from the 1860s as well as "upsa-daisy" . . . any of them with or without hyphens.

The first use of "whoops-a-daisy" per se is around 1925, in a New Yorker cartoon. It's an expression of surprise or dismay, specifically upon discovering one's own error. The modern-day equivalent would be "D'oh!", I'm afraid, which is much less expressive. The term was shortened to "whoops" by 1937, and appears in that form in a letter by Ezra Pound, no less. One assumes that it was related to the expression "to whoop," as in giving "whoops of joy." That usage goes back to the early 1600s.

Group Work:

On the back of your Air Quality worksheet create venn diagram with words comparing your sketches of good and bad air quality.

I should hear a group discussion about what you put on your Air Quality worksheet and teamwork to create the venn diagram that each student must complete on the back side of the worksheet to earn full credit.

Square of Air AssignmentGroup Work- 25 minutes…graded for what you have accomplished in that time frame…spend your time wisely…

Read 2.3 (pgs. 69-76) silently to yourself Then as a group draw our air

Use a sheet of butcher paperMake a key for all components that you draw If oxygen is part of air…how many oxygens would I

see (give it a color) If carbon dioxide is part of air…how many would I see

(give it a color)Etc.

Square of Air Rubric

1. At least 6 different components of air are represented2. A key with color and labels3. All components are drawn to size and the correct number

of molecules are bonded for each part of air4. The page is filled with the correct ratio of all required

components of air5. Effort and Quality

Each item will be assessed on a 1-5 point scale:1 2 3 4 5No Evidence Some Evidence Average Mastery of Task

Composition of Air (Journal Entry)

What elements are in air? What compounds are in air? What molecules are in air? What is the difference between a molecule and compound? Write a sentence or two to classify air. Consider the

following: Element vs. Compound vs. Mixture? Solution (heterogenous or homogenous)? Solvent? Solute?

Draw a pie chart of the composition of the air

HeatEverything else in our garbage that once was alive can go to a different compost pile where micro-organisms break it down. When these little invisible critters eat and breathe they release heat and warm up the compost pile!

WormsWorms will eat your garbage if it once grew from the ground. They are like natures recyclers and would love if you choose to feed them your fruits & veggies instead of throwing your food into a landfill!
