Standard 2.1 Organizing Data Students organize data that represents: ● the energy fow of the system. Students describe what each data set represents including: ● the boundaries of the system and that the reference level for potential energy = 0 (the potential energy of the initial or fnal state does not have to be zero) ● the initial energies of the system’s components (e.g., energy in felds, thermal energy, kinetic energy, energy stored in springs — all expressed as a total amount of Joules in each component), including a quantifcation in an algebraic description to calculate the total initial energy of the system. ● the energy fows in or out of the system, including a quantifcation in an algebraic description with fow into the system defned as positive. ● the fnal energies of the system components, including a quantifcation in an algebraic description to calculate the total fnal energy of the system. Identifying Relationships Students use tools, technologies, and/or models to analyze the data and identify and describe relationships in the datasets, including: ● descriptions of the initial and fnal energy state of the system, along with the energy fows to create a computational model based on the principle of the conservation of energy
