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.
Parallel treatments of photons, electrons, phonons, and molecules as energy carriers, aiming at a fundamental understanding of descriptive tools for energy and heat transport processes from nanoscale to macroscale. Topics include the energy levels, the statistical behavior and internal energy, energy transport in the forms of waves and particles, scattering and heat generation processes, Boltzmann equation and derivation of classical laws, deviation from classical laws at nanoscale and their appropriate descriptions, with applications in nanotechnology and microtechnology.
