This shows students the heat traveling down the rod. Watch the Heat Energy video on YouTube. The concepts in the lesson support the imple-mentation of the 2010–2011 Texas Essential Knowledge and Skills (TEKS) as well as the Texas Eng-lish Language Proficiency Standards (ELPS). (three 60-minute class periods). Since all objects (even -400 °F comets) emit some radiation, an ice cube next to a red hot piece of iron is transferring energy from itself to the iron through radiation. (Slide 5) Talk about what students observed in the demo. As heat conducts down, the wax holding the nails melts and drops the nails, one by one, in sequence. Energy can be transferred in various ways and between objects. Showing 1 - 17 of 17 resources. The phenomenon was named in his honor: Brownian Motion. . Make sure students are able to realize that no heat transfer occurs between objects of the same temperature. Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed. Although radiation does not need air to travel, it can travel through gases, liquids and even some solids. The conduction demonstration requires one candle, matches three small nails/thumb tacks, an oven mitt, and a hacksaw blade or metal rod (not stainless steel). Post-Quiz: After the lesson, and before starting the associated activity, administer the 10-question What Is Heat? convection: the transfer of heat in a fluid (gas or liquid) as … (Slide 6) Make the point that thermal energy is in everything—even if it is something we consider cold. Or melted an ice cube in your hand? Do the images on this slide give you any hints? Expect the presence of energy in a system of jiggling, bouncing, molecules to be very obvious to students who already understand the concept of kinetic energy; indeed, the underlying physical mechanism is similar. 3:54.

In both cases of convection, the jiggling air molecules continue their jiggling when pushed away from the element. Lesson, High School Design of internal combustion engines, air conditioning and heating systems, chemical and biological reactors and even clothing technology requires an understanding of heat transfer. Dark colored objects absorb heat more easily through radiation. 11 Grade English. The energy contained in thermal "jiggling" is a function of many factors such as the mass of the particles and the speed of their motion. In the hair drier, the gaseous air molecules are much freer to move. Alignment agreement: They do this naturally in a process called free convection, which can be described by the familiar mechanism of "hot air rises." Raise your hand if you ever put on a jacket? As evidenced in the choice of materials used for electrical conductors and insulators, most materials with high electrical conductivity also have high thermal conductivity. The best remedy for a burned finger is to put it under flowing tap water. Thermal energy is almost impossible to confine to a location.

At this point, present a conduction demonstration that you have prepared in advance. 8). (Slides 8-13) Use the provided images of a hot cup of coffee, an ice cream cone and a tea kettle on a burner as examples to talk about the direction of heat flow. The person holding the can experiences the sensation of a cold hand because the thermal energy in the hand has flowed, as heat, into the lower temperature soda can and given enough time, the two reach thermal equilibrium. Describe that molecules in a material begin to vibrate (or move) more quickly when the material is heated. Require that they use scientific terminology as part of their explanations. A cast iron pan, left on the stove long enough, requires an oven mitt to handle. sun stroke, homeostasis, body temperature For Students 7th … A hair drier provides an excellent example of convection. In the ASN, standards are hierarchically structured: first by source; e.g., by state; within source by type; e.g., science or mathematics; Identify conduction as heat transfer within and between solids. i.e., most hands-on activities are part of lessons, lessons are grouped into multiday While this material is generally above the sixth-grade level, it presents key background information for the teacher so they are able to answer advanced student questions. Along these lines, "cold" is not a substance that flows. This set of lessons gets students thinking about how heat is transferred through conduction, convection, and radiation.
