## Temperature and Pressure on Airplane Surfaces

Subject Area: Science, Technology, and Mathematics

National Standards:

Science
Apply the concept of force and inertia to predict the motion of objects.

Technology

• Technology Research Tools - Select and apply technology tools for research, information analysis, problem-solving, and decision-making in content learning.
• Technology Problem-Solving and Decision-Making Tools - Routinely and efficiently use on-line information resources to meet needs for collaboration, research, publications, communications, and productivity.

Mathematics

• Read the scale on a measurement device to the nearest mark and make interpolations where appropriate.
• Read, interpret, and use tables, charts, and graphs to identify patterns, note trends, draw conclusions, and make predictions.

Objectives:

After reading the explanation given below, use the World Wide Web to access additional information needed to complete the activities on temperature and pressure.

Consider the relationship between forces and motion on a sizable object. On each element of surface area the adjacent fluid particle exerts, in general, a normal force (pressure) and a tangential force (friction that results in temperature). They both have a component in the direction of the oncoming flows.

In the activities, students are to predict where they think the temperature and pressure will be the greatest and where the pressure will be the lowest before they go online using the first two diagrams. After they have made their predictions, give them copies of the second two diagrams. If you have only one computer, you can project the color diagrams for the students to view.

Assessment:

You, or you and your partner(s), will be evaluated on the accuracy or feasibility of your answers.

Evaluation:

You will be able to use the World Wide Web to access additional information needed to complete the activity that predicts pressure and temperature on an airplane and then allows you to read the color-coded chart to prove/disprove your prediction.
