Subject Area: Physical Science
Grade Level: 6-8
National Science Standards:
- Demonstrate an understanding of how to create and use
models.
- Demonstrate an understanding of and the ability to perform
scientific inquiry.
- Apply an understanding of science and technology.
- Demonstrate and apply an understanding of the properties of
matter.
National Technology Standards:
- Technology research tools: Use content-specific tools,
software and simulations (e.g., environmental probes, graphing
calculators, exploratory environments, Web tools) to support
learning and research; select and use appropriate tools and
technology resources to accomplish a variety of tasks and solve
problems.
- Problem-Solving and Decision-Making Tools - Routinely
and efficiently use on-line information resources to meet needs
for collaboration, research, publications, communications, and
productivity.
Objective:
By using AtmosModeler 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
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
http://www.grc.nasa.gov/WWW/K-12/airplane/atmosi.html.
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
screen.
To use the slider:
- Click the mouse
pointer anywhere near the airplane.
- 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 AtmosModeler to
accumulate data and compare properties of matter, density,
pressure, and temperature.
