The Power of Polymers
Synthesis of a plastic from cornstarch and corn oil. 3-D printing using plastic filament. Use of LEGO manipulatives to illustrate polymerization.
•
Student groups synthesize a variety of polymers and evaluate the suitability of these polymers for particular functions in a car (tires, dashboard, seat cushions, etc.). Chemical structures of polymers, intermolecular forces, performance requirements for automotive parts—strength, flexibility, clarity, chemical resistance. Using molecular models to investigate isomeric structures found in gasoline (notably, isomer of octane). Correlating physical properties (e.g. boiling point) to molecular structures. Distillation of Cherry Coke to obtain three fractions: CO2, flavorings (esters), and residual non-volatile matter (sugar, coloring). Extension of fractional distillation concepts to the production of petroleum distillates (naphtha, gasoline, kerosene, etc.). Investigation of the properties of various weights of motor oils. Relating viscosity data at various temperatures to molecular structures (hydrocarbon chain length). Construction of a model radiator from copper tubing. Investigation of the efficiency of heat exchange. Engineering the system for optimal efficiency. Comparison of commercial antifreeze brands’ ability to depress the freezing point of water. Investigation of specific heat capacity of antifreeze solutions. Investigation of the use of alcohols (methanol, ethanol, isopropanol) to inhibit the freezing of water that may collect in automobile gas tanks and fuel lines.

Calculation of the quantities of CO2 produced in the combustion reactions that provide a car’s energy. Investigation of alternative fuels and analysis of their environmental impact. Investigation of proton exchange membranes and the chemistry of hydrogen fuel cells. Students construct arguments for or against the adoption of fuel cell technology. Investigation of materials required to build a functioning lemon battery. Simulations of how electrons and ions flow in a car battery. Discussion of why a battery is needed in an internal combustion engine.

Investigation of the energy density in batteries compared to the energy density of gasoline. Calculation of mass required for a battery pack that can drive a car for 100-miles. Investigation of biofuels as alternatives to fossil fuels. Evaluation of environmental impacts and economic costs. Students create an e-book to share their conclusions with other students. Researching the pros and cons of carbon fiber as a structural material in automobiles. Students construct evidence-based arguments to support or reject the use of carbon fiber in cars. Examination of galvanic corrosion that occurs when dissimilar metals are bolted together and submerged in a salt water solution. Testing different materials for their ability to decompose hydrogen peroxide. Inquiry = development of a model catalytic converter (using hydrogen peroxide as a hypothetical waste product in engine exhaust). Investigation of the reactions used to inflate airbags. Investigation of the airbag faults that led to the massive Takata airbag recall. Creation of glass from sugar, corn syrup and water. Inquiry: how do the properties of the glass depend on the chemical formulation of the mixture?
