The number of times that the cups spin in a full circle per minute is counted electronically. How do we measure the speed of the wind? Well, wind speed is usually measured using a cup anemometer, which typically has three cups that catch the wind. Some locations always have strong winds from a particular direction, while other locations have little wind or winds that change direction frequently. The direction and strength of the wind are changed by the Earth's environmental surface-which means that the existence of trees, water and various terrain can impact the speed and direction of wind. This pattern of air movement creates wind. Cooler air produces an area of high pressure and moves in under the warm air. Air is heated up by the sun, which causes it to rise. What causes wind? Most people do not know that wind is caused by the uneven heating of the atmosphere. Power Math Worksheet (pdf) 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 Waterwheel Work: Energy Transformations and Rotational RatesĪ Case of Innovation: Technical Writing about River Current PowerĬooking with the Sun: Comparing Yummy Solar Cooker Designsĭesign and Test Model Solar Water Heaters Windmill of Your Mind - Distributed Energy Goes to School Thar She Blows!
