How does altitude relate to density?


Subject Area: Physical Science

Grade Level: 9-12

National Science Standards:

Objective:

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

Estimated Duration: 2 days



FoilSim is an interactive simulation software package that determines the airflow around various shapes of airfoils. As you change the parameters of airspeed, altitude, angle of attack, thickness and curvature of the airfoil, and size of the wing area, the software calculates the lift. The package was created at NASA Glenn Research Center to illustrate an example of the research being conducted here.

Macintosh or MS-Windows 3.x, 95, or NT versions of FoilSim are available for downloading off the World Wide Web at FoilSim Download.

Shown below is a screen shot from the program showing the controls and displays. You may change the values of the variables by using the slider or the input box on the left of the slider.

To use the slider:

  1. Click the mouse pointer on the arrows at the ends of the slider.
  2. Click the mouse pointer anywhere between the slider and the arrow.
  3. Drag the slider with the mouse.

To use the input box:

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 Activity.



Assessment:

You, or you and your partners(s), will be evaluated on the accuracy or feasibility of your answers.

Evaluation:

You will demonstrate the ability to use FoilSim to accumulate data and compare properties of matter, density, pressure, and temperature.
