Materials that are good conductors of heat feel hotter to the touch than materials than are insulators, even if they are at the same temperature! Who remembers what a conductor or an insulator is? A conductor of thermal energy allows heat to pass through its material, so the temperature of the object gets really hot. Microscopically, this thermal energy comes from a whole bunch of tiny little molecules bouncing around and running into each other in an object. When we read a thermometer, we are reading a measure of how much thermal energy an object has. Temperature is actually a measurement of thermal energy. When have you used a thermometer? Have you ever used one when you were sick or to see what the weather was like outside? What are we looking for when we use a thermometer? (Answer: Temperature) Yes, temperature is what is measured on a thermometer. Make Your Own Temperature Scale Worksheet (doc) Visit [ to print or download. The currents may have been produced to begin with by transforming the energy of motion into electrical energy.Įnergy can be transferred in various ways and between objects. In such collisions, some energy is typically also transferred to the surrounding air as a result, the air gets heated and sound is produced.Īlignment agreement: Thanks for your feedback! Light also transfers energy from place to place.Īlignment agreement: Thanks for your feedback! Energy can also be transferred from place to place by electric currents, which can then be used locally to produce motion, sound, heat, or light. When objects collide, energy can be transferred from one object to another, thereby changing their motion. Make observations to produce data to serve as the basis for evidence for an explanation of a phenomenon or test a design solution.Īlignment agreement: Thanks for your feedback!Įnergy can be moved from place to place by moving objects or through sound, light, or electric currents.Īlignment agreement: Thanks for your feedback! Energy is present whenever there are moving objects, sound, light, or heat. This activity focuses on the following Three Dimensional Learning aspects of NGSS: Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.Ĭlick to view other curriculum aligned to this Performance Expectation Develop a scale for measuring temperature on a thermometer they build.Explain how engineers use thermometers in everyday applications.Describe the physical changes that occur in a thermometer with increasing or decreasing temperature.After the space shuttle malfunctioned during takeoff a few years ago, engineers found the cause of the problem through the use of temperature data from probes located throughout the shuttle's wing that was hit by a piece of dislodged insulation.Īfter this activity, students should be able to: In other applications, such as power plants, industrial manufacturing facilities, labs, aerospace equipment and medical equipment, temperature measurements are used as well. A control system monitors these temperatures and adjusts the amount of heating, cooling, and other systems in response to the measurements. For example, to keep a building's indoor environment comfortable for people, mechanical engineers continually take temperature measurements of building zones, supply air, outside air, and chilled and hot water supplies. Engineers use temperature as an indicator of how well a system is operating or if it is operating within its design limits.
