### 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.
