Beginner's
Guide to Propulsion
Air Temperature and Kinetic Energy
Subject Area(s): Mathematics (Pre-Alegebra)
Grade Level: 7 - 9
National Standards:
Mathematics
Mathematics
as Problem Solving - Use, with increasing confidence, problem-solving
approaches to investigate and understand mathematical content.
Mathematics as Communication - Formulate mathematical definitions
and express generalizations discovered through investigations.
Algebra - Represent situations that involve variable quantities
with expressions and equations.
Functions - Represent and analyze relationships using tables,
verbal rules, equations and graphs.
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.
Problem-Solving and Decision-Making 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 using the kinetic energy formula
along with scientific notation.
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 Static Gases, click on the slide
called Air
Temperature. Read the explanation to see how air temperature and kinetic
energy are related to aircraft propulsion. Using this information, complete
the Activity and Worksheet
to demonstrate your ability to use the kinetic energy formula.
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 data on various gases and apply it to
the kinetic energy formula using scientific notation.
