Then place it in the freezer for a few minutes. Can you think of another example when temperature makes something expand or contract? Try this at home: Blow up a balloon or a plastic bag and tie it off. The liquid inside the thermometer contracts when the temperature gets cold. The opposite word for expand is to contract, or when something gets smaller. When something expands, it means that it gets bigger. It rises because heat makes the liquid expand. What happens when the temperature goes up in a thermometer? The liquid inside the glass tube rises. 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.
