● I can design, construct and test a device that will affect the rate of a phase change and compare competing devices to improve performance. ● I can defne and model energy transfer (conduction, convection, radiation). ● I can differentiate between an insulator and a conductor. and test a device that will affect the rate of a phase change and compare competing devices to improve performance. ● I can defne and model energy transfer (conduction, convection, radiation). ● I can differentiate between an insulator and a conductor. ● I can design, construct
