http://www.daviddarling.info/encyclopedia/R/Rumford.html Read about Rumford's experiment. (Homework) The day after the homework reading, the students discussed in small groups the flows of energy that were involved in the making of the cannon. They diagrammed the cause and effect relationships that were happening at the macroscopic level (horse, metal boring machine, water) and also at the invisible level of the water particles. After extensive small group and teacher-facilitated whole class sharing of diagrams and discussions, they reached the following consensus statements: The following day, Mr. A introduced the design challenge for students in teams of three to design, construct, and test a device that either minimizes or maximizes the transfer of thermal energy. Mr. A facilitated a whole class discussion about constraints (such as safety, cost, class time, and availability of materials/equipment) and criteria for success. Student teams brainstormed the materials and the flows of thermal energy that they would investigate. In their initial design proposal, they specified the materials and processes they would use and how they would test their devices. Student teams provided most of the feedback to each other, with Mr. A intervening only as absolutely needed to keep the teams on task and within the criteria and constraints. The engineering challenge concluded with student teams presenting and comparing their project results and how their projects developed over time.
 * the motions that the people saw caused the heating and boiling that they could feel and see;
 * at the macroscopic level (our level), kinetic energy of the horse transferred to kinetic energy of the iron boring machine which transferred to thermal energy of the water;
 * at the particle level, kinetic energy of the boring machine transferred to kinetic energy of the water particles.
