Subject Area: Algebra II

Grade Level:11-12

National Mathematics Standards:

• Apply integrated mathematical problem-solving strategies to solve problems from within and outside mathematics.
• Read written presentations of mathematics with understanding.
• Follow logical arguments.
• Use and value the connections between mathematics and other disciplines.
• Operate on expressions and matrices, and solve equations.
• Understand the logic of algebraic procedures.

National Technology Standards:

• 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.

 Objective:

After reading an explanation from a NASA Web-based textbook, you will use physical data to solve equations described in the text.

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 Trimmed Aircraft (with text) and read the explanation of the equations for trimmed aircraft and total aircraft lift. Then using the information shown at Trimmed Aircraft Equations Problems, and additional information which you will access from the World Wide Web, complete the problems designed to demonstrate your ability to solve equations relating to aircraft data and to use matrices to solve a system of linear equations.

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 equations using physical parameters.
