Grades 9–12. Calorimetry provides firsthand experience with the transformation of chemical energy to thermal energy. This lab is based on the phenomenon of the diesel engine as a thermal system. Students calculate the heat of combustion for prepared biodiesel, corn oil, and canola oil. Those values and the provided data for traditional petrodiesel fuels allow students to support their claims about the relative functionality of each fuel.

Students will generate data by calculating heat of combustion for 2 biofuels, compare that data to traditional petrodiesel fuel, and then use the data to develop an explanation of energy transfer, which will be employed to assess the benefits of potential use of biodiesel fuels.

PE: HS-PS3-1, ESS3-2, and ETS1-3
Time Requirement: 45 minutes

SEP: Constructing Explanations and Designing Solutions
DCI: PS3.B: Conservation of Energy and Energy Transfer
CCC: Energy and Matter: Flows, Cycles, and Conservation

Grades 9–12. The first law of thermodynamics states that energy cannot be created or destroyed but can be transformed or transferred. In this calorimetry activity, students gain firsthand experience with the transformation of chemical energy to thermal energy. Students are asked to show how energy transformation and transferal occurs in both a diesel engine and the calorimeter model. By comparing the calculated heat of combustion of fuels and oils provided and known values for traditional petrodiesel, students support their claims about each fuel's functionality.

This kit is designed to be incorporated into a larger unit of instruction consisting of multiple experiences and taking place over several weeks. Anchoring phenomena for a larger unit of instruction may be derived from the following topics:

  • Organic chemistry
  • Thermochemistry
  • Climate change

If you have separatory funnels on hand, then this lab also offers you an optional opportunity to teach students an advanced technique for separating liquids. Materials are sufficient for 32 students working in pairs and include free 1-year access to digital resources that support 3-dimensional instruction for NGSS. Note: The biodiesel sample preparation process that is required before students begin the activity takes a minimum of 6 calendar days from start to finish.
