Conductors and Insulators

A _ is a material that allows electricity or heat to easily flow through it. conductor insulator rubber supressor Materials that block the flow of electricity or heat are known as - _. conductor insulators metallic dividers Sort it out! Look at each of these common items and separate them into categories by insulators or conductors. Click each term and select either insulator or conductor. Conductor penny key paper clip brass fastener quarter door knob copper wire Insulator paper toothpick plastic fork rubber band glass tape Many objects that conduct electricity or heat are made from this material. Metals Plastics Wooden Cotton The outside of electrical wires often have a layer of insulation to protect the user from being shocked. This protective layer is often made from - flexible woods rigid metals flexible plastics rigid glass Match the term to the best definition or description of the word's meaning. conductor allows electricity to easily flow material what an object is made of metallic an object that is made up of metals insulator blocks the flow of electricity properties characteristics of materials Sort it Out! Separate the conductors from the insulators. Click each image and select either insulator or conductor. conductors Insulators How can you tell if the object connected in this simple circuit is a conductor or insulator? The bulb will not light if it is a conductor The bulb will light if it is a conductor The bulb will light if it is an insulator none of these is correct Is it an insulator or a conductor? Watch this video. Answer the next two questions based on what you see. In the video, pork chops are placed on a cookie sheet. Is the cookie sheet an example of an insulator or a conductor? Provide specific evidence from the video and from your notes to explain your answer. Toward the end of the video, you see cookies baking inside of a car. In this part of the video, do you see an example of an insulator or a conductor? Provide specific evidence from the video and from your notes to explain your answer. Houses have insulation in the attic. This insulation traps a lot of air and helps to keep the house cooler in the summer and warmer in the winter. Which of the following statements is correct? This is an example of a conductor. The insulation conducts heat in the winter to keep the house warm. This is an example of a conductor. The insulation prevents the flow of thermal energy. This is an example of an insulator. The insulation prevents the flow of thermal energy. This is an example of an insulator. The insulation conducts heat in the winter to keep the house warm. You are sitting at a wooden desk. The chair you are sitting on is plastic and has metal legs. All three of the objects are in the same room with a constant temperature. You touch the wooden desk, the plastic on the chair and the metal legs. How does the temperature of each surface compare Explain your answer. Your answer should include the words insulator, conductor, thermal energy, hot and cold.
