1. Science Starter 4/22/15 Grab Notebook from bin
Add Unit 5:Atmosphere & Weather
As you climb up a mountain,
do you expect to experience
increasing or decreasing
temperatures?
What if that mountain was tall enough to extend into space. What changes would you experience in temperature?

2. Classroom Procedures
When you enter the classroom, earbuds and cell phones must be AWAY
You come in and go to the bin to grab your notebook silently
You have a seat in your assigned seat silently
You begin your Do Now silently and independently
Once time is up, you put your pencils down, and track the speaker! This task is also done silently and independently

3. Cell Phone Policy Beginning of class, cell phone away
If I see a cell phone when class begins (charging, in hand, music) I will ask for it ONE TIME
Turn it over and I will return it to you after class
Don’t turn it over and I will write a referral (still expected to put phone away for remainder of class)
You may only take out cell phones if I say it is allowed
Must put them away/on top of desk if I am talking
I should never hear your music/ringtone/any noise

4. What determines the layers of the atmosphere?
Essential Question
What determines the layers of the atmosphere?

5. Objective
Students will be able to identify the different layers of the atmoshphere by completing a graphic organizer

6. What are the layers of the atmosphere in ascending order (from the ground up)
What are the boundaries between the different layers of the atmosphere?
In which layers does temperature increase with elevation?
In which layers does temperature decrease with elevation?

7. CORNERS! Layers of the Atmosphere
For each of the following questions, guess the atmosphere layer that you think is described by the statement presented.
After each question is posed, you will write the statement in the correct layer column

9. Troposphere
The layer where WE live
Weather happens here

10. Thermosphere
Temperature increases as you get higher (sun’s rays slow down)
Site of Aurora Borealis (ionosphere)

11. Stratosphere Contains the ozone layer
Temperatures increase as you go up (ozone traps heat)

12. Mesosphere Coldest layer (down to -90oC)
Very few gas molecules (low pressure)

13. Satellites orbit here (exosphere)
Thermosphere
Too few gas molecules for thermometer to accurately measure temperature
Satellites orbit here (exosphere)

14. Troposphere
Earth’s heat warms the air, so temperature decreases as you go higher up
Extends 7 miles up
Most dense layer

15. Stratosphere
Where airplanes fly
Extends 7-30 miles

16. In which layer do humans live?
In which layer is the ozone layer found?
In which layer does weather occur?
Which layer is the coldest?
Which layer contains the Aurora Borealis?

17. Unit 5: Atmosphere & Weather
Grab a book and turn to Chapter 17
Complete both of sides the sheet introducing the atmosphere
These should be completed (front & back), stapled, and placed in your notebook under Unit 5
