Grade levels: Senior High (10-12)

Illustrates multi-step energetics problems with various real-life situations. Stresses the steps that should be applied in problem solving: identify changes; relate known to unknown; calculate the answer; and check the answer.

Examining commercial primary cells show: electrolyte composition; oxidation and reduction half-reactions; and anode and cathode. Experiments on primary cells arranged in a series show that the total voltage is the sum of the cells in the series.

Photosynthesis and cellular respiration are examples of potential energy changes calculated using Hess’s Law. The molar enthalpy of combustion of hydrocarbons is calculated and compared to the molar enthalpy of respiration.

Explores the similarities and differences of voltaic and electrolytic cells. The same steps to predict voltaic cell reactions can be used to predict non-spontaneous electrolytic reactions. Discusses industrial applications of electrolysis.

This program focuses on energy efficiency. Students compare the efficiency of different water heater designs using controlled and responding variables, and the molar enthalpies of different fuels.

Secondary cells are defined and compared to primary cells. Equations that show the rechargeable aspect of secondary cells are explained using a lead storage battery. Discusses the uses and advantages of fuel cells.

Compares the energy of a phase change, chemical change and nuclear change. Explains the conversion of mass to energy using Einstein’s equation, E =mc². Explains the concepts of radiation, fission and fusion.

Explains how metals are obtained from molten ores and presents a historical perspective of Sir Humphrey Davy’s work. Explores similar technology used today in the Hall process, the Downs cell and the formation of magnesium metal.

Our reliance on fossil fuels is the basis for a risk/benefit analysis of energy sources. The advantages and disadvantages of fossil fuels are discussed and several alternate energy sources reviewed.

Discusses Michael Faraday’s contributions to science. Explains electrical units and the Faraday, and the relationship between current, time and mol of electrons. Sample problems demonstrate the stoichiometric connection to electrolysis.
