Roadmap Objectives:

• • Article: Measurement of thermal expansion coefficient, Trumper and Gelbman.
  • Content area/major concepts: coefficient of linear expansion, heat transfer, thermal expansion
  • Methods or technology used to obtain data: Paper describes a method for measuring the thermal expansion of a metal wire. The measurement is used to find the coefficient of linear expansion. The theory is linear expansion
  • How the CREATE strategy was used:
  • Biggest teaching challenge:
• • Article: Uncertainty analysis for a simple thermal expansion experiment. Dounas-Frazer, Gandhi, and Iwata
  • Content area/major concepts: limits of assumptions. (Physics often makes assumptions to find an answer that is reasonable more easily. For example, a “massless” rope, or a “perfectly rigid lever” i.e., the lever will not ever bend. This leads to the Spherical Chicken Joke)
  • Methods or technology used to obtain data: Paper describes sources of measurement error for the method used in paper 1
  • How the CREATE strategy was used:
  • Biggest teaching challenge:
• • Article: Revisiting Black’s experiments on the latent heats of water. Guemez, Fiolhais, Fiolhais.
  • Content area/major concepts: latent energy, heat of fusion, heat of vaporization, specific heat capacity, calorimetry, heat transfer, energy conservation, the calorie unit of energy, Newton’s Law of Cooling.
  • Methods or technology used to obtain data: Paper describes the methods originally used by Black when he found the latent energies of condensation and fusion of water. The paper describes Black’s experiment and gives a way of replicating that experiment with modern equipment. The theories covered are energy needed for the change in temperature of a solid and needed for the change of state.
  • How the CREATE strategy was used:
  • Biggest teaching challenge: I would like to do the heat of fusion lab described in the paper. That would be an easy lab to do, but will cut into class time. Also, this is a new method for me and I expect that I will have difficulties applying it.
• • Article: Condensation, atmospheric motion, and cold beer. Durran and Frierson.
  • Content area/major concepts: P-V work, enthalpy, convection, adiabatic process, humidity and relative humidity, evaporative cooling, condensative warming, radiative cooling.
  • Methods or technology used to obtain data: Paper describes a method for finding the amount of heating that is due to the condensation of water on a cold can of water. The theory given uses the latent heat of condensation to find the temperature change of the water.
