Guide to Aerodynamics
Density and Lift
Subject Area:
Physical Science
Grade Level:
6-8
National Science
Standards:
- Physical Science:
- Motions and
Forces.
- Properties
and changes of properties in matter.
- Science and
Technology:
- Abilities of
technological design.
- Understandings
about science and technology.
National Technology
Standards:
- Technology productivity
tools: Use of content-specific tools, software and simulations (e.g.,
environmental probes, graphing calculators, exploratory environments,
Web tools) to support learning and research; application of productivity/multimedia
tools and peripherals to support personal productivity, group collaboration,
and learning throughout the curriculum.
- Technology research
tools: Select and use appropriate tools and technology resources
to accomplish a variety of tasks and solve problems.
- Technology problem-solving
and decision making tools: Application of productivity/multimedia
tools and peripherals to support personal productivity group, collaboration,
and learning throughout the curriculum.
Objectives:
After reading
from a NASA Web-based textbook, you will demonstrate an understanding
of the text by solving problems on density and predicting which density
will give the most lift.
Beginner's Guide to
Aerodynamics is a "textbook" of information prepared at NASA Glenn
Research Center to help you better understand how airplanes work. Click
Beginner's Guide Index to access
the list of slides. Open the slide called Air
Density and study the examples. Next, open the slide called Momentum
Effects. Look at the very bottom of the page, noting how changes in
density affect the lift.
Then using the information
shown at Airspeed Problems, complete the
questions.
Assessment:
You, or you
and your partner(s), will be evaluated on the accuracy or feasibility
of your answers.
Evaluation:
You will
demonstrate the ability to use information found on the World Wide Web
to solve problems involving density and lift.
