They also learn about examples of heating and cooling devices, from stove tops to car radiators, that they encounter everyday in their homes, schools, and modes of transportation. Since in our everyday lives there are many times that we want to prevent heat transfer, students also consider ways that conduction, convection, and radiation can be reduced or prevented from occurring.
Engineers encounter problems of warming and cooling liquids in a number of situations. For soda, this usually involves maintaining a cold temperature, but the principles described here are the same. Students approach the problems presented in this activity as engineers, using heat transfer principles to accomplish a goal.
In the context of heat transfer, students will be able to define the terms conduction, convection and radiation.Students will be able to describe ways people try to cause or prevent heating and cooling by conduction, convection, and radiation in everyday life.Students will be able give examples of materials that serve well for heating by conduction, convection, and radiation. 2.5TeachEngineering.orgMary R.
