Product Details

Concerns about global warming and the depletion of energy sources have generated widespread interest in alternative, renewable fuels. Take advantage of that interest by using this student lab kit to have students prepare and analyze biodiesel fuel. The biodiesel fuel methyl stearate is prepared by mixing cooking oil with methyl alcohol and sodium hydroxide. Students use common separation techniques to isolate the biodiesel fuel and then determine the fuel's heat of combustion by calorimetry. The real-world application of this lab makes it an effective learning exercise for students who would otherwise lose interest in purely chemical discussions of thermochemistry and heats of combustion. Includes Teacher Notes, extensive background material, reproducible student handouts, and all necessary chemicals and specialized equipment. Complete for 30 students working in pairs. Funnel and ring support are required and available separately. Perform this experiment in a fume hood or well-ventilated lab.

Performance Expectations

MS-PS1-6. Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes.
MS-PS3-4. Plan an investigation to determine the relationships among the energy transferred, the type of matter, the mass, and the change in the average kinetic energy of the particles as measured by the temperature of the sample.
HS-PS3-3. Design, build, and refine a device that works within given constraints to convert one form of energy into another form of energy.
