Problem:
How does temperature, air pressure, and the density of the air change among the layers of the atmosphere?
Hypothesis:
Temp.-_____________________________________________________________________________________________
Press.-_____________________________________________________________________________________________
Density-____________________________________________________________________________________________
Objective:
To describe (click here to learn) the structure of the Earth’s atmosphere and the phenomena that occur in each layer.

Click here or the website in the title above to boot up the Layers of the Atmosphere Interactive activity.
Read aloud about the atm. Layers scrolling through the online information on the left side of the screen.
Record the atmospheric data (density, pressure, and temp.) for sea level, 0 km, in the data table below.
Drag the red slider (
) up and choose the next altitude listed in the data table.
Click the Launch button to send the balloon or rocket up to collect atmospheric data.
Record the new atmospheric data from the bottom of the screen into the data table.
If the Show Phenomenon button becomes enabled, click to learn what else occurs at that level.
Repeat the exploration for each of the ten other altitudes.
Troposphere = 0-10 km
Then Graph the data. The first two data points have been graphed. Be prepared to go off the scale.
Stratosphere = 11-50 km
Complete the Analysis and Conclusion questions.
Mesosphere = 51-80 km
Thermoshpere = 81-500 km
