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.
