Conduction, Convection and Radiation

With the help of simple, teacher-led demonstration activities, students learn the basic concepts of heat transfer by means of conduction, convection and radiation. Then they apply these concepts as they work in teams to solve two lab problems: 1) maintain the warm temperature of one soda can filled with water at approximately body temperature, and 2) cause an identical soda can of warm water to cool as much as possible during the same 30-minute time interval.
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 unit's activity as engineers, using heat transfer principles to accomplish a goal.
- CCSS.Math.Content.6.EE.C.9 Use variables to represent two quantities in a real-world problem that change in relationship to one another; write an equation to express one quantity, thought of as the dependent variable, in terms of the other quantity, thought of as the independent variable. Analyze the relationship between the dependent and independent variables using graphs and tables, and relate these to the equation.

This resource focuses on the following Three Dimensional Learning aspects of NGSS:
Science & Engineering Practices- Plan an investigation individually and collaboratively, and in the design: identify independent and dependent variables and controls, what tools are needed to do the gathering, how measurements will be recorded, and how many data are needed to support a claim.Do you agree with this alignment?
- Science knowledge is based upon logical and conceptual connections between evidence and explanations.Do you agree with this alignment?
Disciplinary Core Ideas- Temperature is a measure of the average kinetic energy of particles of matter. The relationship between the temperature and the total energy of a system depends on the types, states, and amounts of matter present.Do you agree with this alignment?
- The amount of energy transfer needed to change the temperature of a matter sample by a given amount depends on the nature of the matter, the size of the sample, and the environment.Do you agree with this alignment?
Crosscutting Concepts- Proportional relationships (e.g. speed as the ratio of distance traveled to time taken) among different types of quantities provide information about the magnitude of properties and processes.Do you agree with this alignment?
