“…For the achievement of these Basic Competencies, several indicators are obtained, namely students can: 1) mention the various sources of heat energy that exist in the surrounding environment; 2) mentioning how heat is propagated in the surrounding environment; 3) explain the differences in heat propagation through conduction, convection, and radiation; 4) mention the various sources of sound energy in the surrounding environment; 5) explain that sound is produced by vibrating objects; 6) explain the difference in sound, pitch, frequency, and amplitude; 7) explain the difference between infrasound, audiosonic, and ultrasonic sound; explain the propagation of sound through solid, liquid, and gas media; and 9) explains that sound can be reflected. With these indicators, students are expected to understand heat energy and sound energy can occur in their daily lives (Mahardika, Chusni, & Istiningsih, 2017). With these indicators, students are expected to understand heat energy and sound energy and their properties that occur in their daily lives (Saripah & Mulyani, 2015).…”
