This lesson covers concepts of energy and energy transfer utilizing energy transfer in musical instruments as an example. More specifically, the lesson explains the two different ways in which energy can be transferred between a system and its environment. The law of conservation of energy will also be taught. Example systems will be presented to students (two cars on a track and a tennis ball falling to the ground) and students will be asked to make predictions and explain the energy transfer mechanisms. The engineering focus comes in clearly in the associated activity when students are asked to apply the fundamental concepts of the lesson to design a musical instrument. The systems analyzed in the lesson should help a great deal in terms of discussing how to apply conservation of energy and energy transfer to make things.

Engineers must understand energy transfer to design instruments that produce beautiful music. Energy transfer is a central concept in the majority of engineering designs. At the end of this lesson, the student should be able to define energy, heat, energy transfer, work, and thermal equilibriumAt the end of this lesson, the student should be able to state how to utilize the concept of energy transfer to make a musical instrumentAt the end of this lesson, the student should be able to state the law of conservation of energyAt the end of this lesson, the student should be able to define a system and environment in terms of energy, and describe how energy transfer occurs between the two 1TeachEngineering.orgAdam Kempton (Lesson creator/editor), Duke University, Pratt School of EngineeringHalliday, Resnick, Krane, “Physics.” John Wiley & Sons, Inc., 2002Beichner, Serway, “Physics for Scientists and Engineers.” Saunders College Publishing, 2000.S102848BNorth_CarolinaScience6.02 Analyze heat flow through materials or across space from warm objects to cooler objects until both objects are at equilibrium.66S102848CNorth_CarolinaScience6.03 Analyze sound as an example that vibrating materials generate waves that transfer energy.<br /> &#8226; Frequency.66S1028499North_CarolinaScience6.07 Analyze the Law of Conservation of Energy:<br />&#8226; Conclude that energy cannot be created or destroyed, but only changed from one form into another.66United StatesCopyright 2012 - Engineering K-Ph.D. Program, Duke University, Pratt School of Engineeringhttp://www.teachengineering.org/policy_ipp.phphttp://www.teachengineering.org/2008-09-266Teacher
