 * Inquiry Question: How does an understanding of heat transfer help in the design of consumer products that reduce the rate of heat transfer?**


 * Background Information:**

Within a two week unit on heat transfer, students will have engaged in lessons that demonstrate the following concepts and ideas: - Heat moves in predictable ways, moving from warmer objects to cooler ones until they reach equilibrium by the processes of conduction, convection, and radiation - As the thermal energy of an object increases, so does the movement of the particles in the object. As the thermal energy of an object decreases, so does the movement of the particles in the object (Kinetic Theory of Matter). As a result of this movement of particles, there will be more or fewer collisions among those particles. - How to use and read a thermometer/temperature probe - Continue sharpening skills to interpret and make meaning of data collected during a scientific investigation - The particulate nature of solids, liquids, and gases as well as how the density of the particles in various states of matter may affect a substance's ability to conduct thermal energy


 * MA Curriculum Frameworks Addressed:**

Physical Sciences (Chemistry and Physics), Grades 6–8:

14. Recognize that heat is a form of energy and that temperature change results from adding or taking away heat from a system.

16. Give examples of how heat moves in predictable ways, moving from warmer objects to cooler ones until they reach equilibrium.

Groups of students will choose one of the following options to investigate heat transfer by conduction: - design & build an insulating sleeve to keep a hot drink hot or a cold drink cold or __both__, - choose and compare various surfaces’ ability to melt an ice cube, - choose three items to place in hot water.... place tab of butter on end of item... see which tab of butter melts first (which materials are best to use for stove top cooking), or - design your own experiment that demonstrates heat transfer by conduction of different materials.
 * Project Description:**

In each case, students are choosing the materials to test, designing & carrying out the experiment, reporting results by creating a presentation, & commenting on other students' investigations.

- flip camera - Glogster - Internet - webcam - cell phone - digital camera - temperature probes - Jing - graphing websites for presenting data
 * Technology Materials:**

Students will create a presentation using VoiceThread, Glogster, or another type of presentation media. Additionally, students must comment on at least 2 other groups' lab results. Students should comment on 1 other group that conducted the same investigation and 1 group that conducted a different investigation. Comments should (at the very least) include: 1 commendation, 1 recommendation, and 1 question for discussion.
 * Final Product:**

[|Heat Transfer Glog]
 * Example:** This Glogster could be used as an example for student work or as a way to introduce the assignment.
