National Standards:
Mathematics
Mathematics
as Problem Solving  Apply integrated mathematical problemsolving
strategies to solve problems from within and outside mathematics.
Mathematics as Communication  Formulate mathematical definitions
and express generalizations discovered through investigations.
Algebra  Use tables and graphs as tools to interpret expressions,
equations and inequalities.
Statistics  construct and draw inferences from charts, tables,
and graphs that summarize data from realworld situations.
Technology Research Tools  Routinely and efficiently use online
information resources to meet research needs.
Technology
Research
Tools  use contentspecific tools, software and simulations (e.g.,
environmental probes, graphing calculators, exploratory environments,
Web Tools) to support learning and research.
ProblemSolving and DecisionMaking Tools  Routinely and efficiently
use online information resources to meet needs for collaboration,
research, publications, communications, and productivity.
Objectives:
After reading
an explanation from a NASA Web site called The
Beginner's Guide to Propulsion, you will demonstrate an understanding
of the text by completing a worksheet on thrust to weight ratios.
The
Beginner's Guide to Propulsion is a Web site of information prepared
at NASA Glenn Research Center to help you better understand aircraft
engine propulsion. Click the Beginner's
Propulsion Index to access the list of slides. Go to the bottom
of the page and click on the yellow button that gives you the Short
Index. Open the slide called Thrust
to Weight Ratio under the heading of Aircraft Motion and read the
explanation. Then using the background information given at Thrust
to Weight Ratio Activity, complete the worksheet designed to demonstrate
your ability to research data on the Internet, complete a table, and
calculate ratios using the appropriate numbers.
Assessment:
You, or
you and your partner(s), will be evaluated on the accuracy and/or feasibility
of your answers.
Evaluation:
You will
demonstrate the ability to use and understand information found on the
World Wide Web by completing an activity on propulsion and using researched
data to complete a table and calculate the Thrust to Weight Ratio for
various airplanes.
