By using AtmosModeler computer simulation software, you will
demonstrate an understanding of the properties of matter by
applying them to density, pressure, and temperature.

AtmosModeler is an interactive
simulation software package that calculates the 1976 U.S. Standard Atmosphere
properties. As you change parameters such as airspeed and altitude,
the software calculates the pressure, temperature, speed of sound and Mach number.
The package was created at the NASA
Glenn Research Center.
AtmosModeler is a Java applet program that executes inside the browser of your computer.
It is available on the World Wide Web at
You can also
download the program to run off-line.
You may change the values
of the variables by using the airplane slider on the left of the
To use the slider:
- Click the mouse
pointer anywhere near the airplane.
- Drag the slider
with the mouse.
To use the input
Simply select the
value in the input box, key in the new value, and press Enter or Tab when
finished. The button on the slider will move corresponding to the value
typed in the box.
Use the simulation to gather information for the Density Problems
and to check your answers. To begin the problems, click on Density
You, or you and your partners(s), will be evaluated on
the accuracy or feasibility of your answers.
You will demonstrate the ability to use AtmosModeler to
accumulate data and compare properties of matter, density,
pressure, and temperature.
