Subject Area: Mathematics (PreAlgebra, Geometry)
Grade
Level: 79
National Standards:
Mathematics
Mathematics
as Problem Solving  Use, with increasing confidence, problemsolving
approaches to investigate and understand mathematical content.
Mathematics as Communication  Reflect upon and clarify their
thinking about mathematical ideas and relationships.
Algebra  Represent situations that involve variable quantities
with expressions, equations, inequalities, and matrices.
Geometry  Represent problem situations with geometric models
and apply properties of figures.
Technology
Research
Tools Use contentspecific tools, software and simulations (e.g.,
environmental probes, graphing calculators, exploratory enviromnets,
Web tools) to support learning and research.
ProblemSolving and DecisionMaking Tools  Routinely and efficiently
use on line 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 relating to the crosssectional
areas of turbine engine inlets.
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 Beginner's Guide
to Propulsion to access the list of slides. In the "Short
Index" under the heading of Turbine Engine Parts, click on
the slide called Inlets. Read
the explanation to see how inlets apply to the propulsion of an airplane.
Using this information, complete the Inlet
Activity to demonstrate your ability to complete calculations on
crosssectional areas of inlets.
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 calculate the area of a figure and see how
it relates to engine inlets and airplane propulsion.
