Electricity passes first through one component first then the next one. Current does not flow easily through rubber, which makes it a good insulator to wrap around the copper wire.). Muir, Hazel. Do you think rubber is a good or poor conductor? In a hands-on activity, students induce an electrical charge on various objects, and experiment with electrical repulsion and attraction. How can it be explained in our water system analogy? (Slide 2) Prompt: A power outage has just happened in your city. After completing the associated static electricity activity, have students recap the activity using scientific terms to explain what happened. electricity: The presence or movement of electric charges. (Slide 10) Rubber is an example of a good insulator. www.teachengineering.org/lessons/view/ucd_electricity_lesson01, Search curriculum by Common Core standards, Print lesson and its associated curriculum, Click to view other curriculum aligned to this Performance Expectation, Electrical Careers Research Project Handout (docx), Electrical Careers Research Project Handout (pdf), Take Charge! Objects may gain or lose electrons. The key point is that flow is movement! its parts.' For example, brainstorm as a class and then give students 15-20 minutes to write on their own. Electricity can be used to perform work such as: But where do these items get their electricity? DGE 0948021. How about as the wire gets shorter? Most curricular materials in TeachEngineering are hierarchically organized; In this creative writing exercise, students are asked to use at least four of the following terms provided in a word bank on the handout: electricity, atom, static electricity, proton, neutron, electron, conductor, insulator and current. curricular units and these again are bundled into subject areas. Many fields of engineering require that people have a good understanding of electricity. "), (Slide16) Let's go through some review questions and answers. (Answer: Electrical current flows more easily in conductors because electrons move better in conductors. Another name for this path is a circuit. An electricity transmission tower.copyrightCopyright © 2006 Yummifruitbat, Wikimedia Commons http://commons.wikimedia.org/wiki/File:Pylon_ds.jpg. Electricity flows from the power source, in a loop or a circuit, back to the power source. if the loop is not closed) then electricity cannot flow through it properly. (Give students some time; then ask a few students to share their answers. Students are introduced to the fundamental concepts of electricity. Then, have students write their own scenarios involving electricity and engineers. Refer to the drawings on this slide as you relate back to the water flow demo. Presentation (slides 16-19). Remind students of the two types of charged particles in an atom (protons and electrons). All appliances, whether small or large, need a power source. Students come to understand static electricity by learning about the nature of electric charge, and different methods for charging objects. Do you think electrical current flows more easily in conductors or insulators? Power Discovery Zone, South California Edison: e-smart Each circuit component has it’s own symbol. Electrical Vocabulary Then re-emphasize the water analogy to cement the connection. I am a new user and maybe it’s a bit presumptuous of me to suggest content but….I’m doing ‘Electricity’ in science right now with my grade 5/6 class and would love to see that included in your website beyond the Ben Franklin reference. The current is sent through transformers to increase the voltage to push the power long distances. (Slide 13) In water systems, current is the flow of water. In the ASN, standards are hierarchically structured: first by source; e.g., by state; within source by type; e.g., science or mathematics; In preparation for review questions, ask students to think of other metals they know about. Where would an electrician use an insulator? If not, spend more time on this topic. (Answer: Electricians use insulator material around electrical wires and the handles of tools and other equipment. Think of the periodic table and the primary elemental components of these materials (silicon for glass, carbon for wood, and carbon and oxygen for rubber). Do you agree with this alignment? 5-PS1-1. Critical thinking question: We know that insulators and conductors are opposites. Thus, understanding electricity is important in our daily lives. Students are introduced to the concept of electricity by identifying it as an unseen, but pervasive and important presence in their lives. Conductors and Insulators: one continuous loop. Electrical current needs a PATH on which to travel. (Slide 12) Next we'll discuss current, which is the flow of electricity/electrons. ), Are insulators such as glass, wood and rubber considered metals or nonmetals? Tiny Pen Pals: To test for understanding of electrical terms, give students the Particle Pen Pals Assignment, which asks them to use terms learned in the lesson in context to describe electricity through storytelling: Pretend you are an electron and you are writing a letter to your favorite proton telling him/her that you are moving away. Substances are made from different types of atoms, which combine with one another in various ways. (Slide 4) What are atoms? Correlate the flow of water with the flow of electricity in a system. (Answers: Gold, silver and aluminum.) Free K-12 standards-aligned STEM curriculum for educators everywhere. Thus, charge collects in a similar way to how water collects behind a dam. They are made of electrons, protons and neutrons. Electric charge is the physical property of matter that causes it to experience a force when near other electrically charged matter. 5), Develop models to describe the atomic composition of simple molecules and extended structures. "Electricity." (Slide 11) Is the photograph labeled correctly with which is the conductor and which is the insulator? ), (Slide 18) We have shown that copper is a conductor. Presentation, a PowerPoint® file, guided by the slide notes below. A power source provides a steady flow of electrons. It can also mean the energy you get when electrons flow from place to place. The electric current from the power source flows from one place to another through the wire of a circuit. Copper is a metal; most metals make good conductors. As desired, provide additional information on the topic, such as: engineers make, control and give us ways to use electricity.). that a switch opens and closes a circuit.' The center nucleus contains the protons and neutrons. It may help to think of the mnemonic device of: "STATIc electricity is STATIonary"—it does not move. Encyclopaedia Britannica Online. Generating Electricity : Things Which Use Electricity : Uses of Electricity : Electrical Vocabulary Half-a-Minute (anagrams game) Electricity Vocabulary Hangman-style game. say whether a lamp will light or not in a simple series circuit.' When students answer correctly, click to reveal the "poor conductor" bullet. In a hands-on activity, students build a conductivity tester to determine whether different objects are conductors or insulators. We get electricity, which is a secondary energy source, from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources, which are called primary sources. Over the next few days here’s what I put together for her and her 5/6 Grade Class in BC: Electricity is a very useful form of energy. Heating our homes or our food (electrical energy is converted into light and heat energy), Lighting our lamps (electrical energy is converted into light and heat energy), Powering our computers (electrical energy is converted into light, heat and sound energy) or. 6). Generating stations can use wind, coal, natural gas, or water. It is used to power lights, mobile phones, TVs, radios, and even the. Learning Objective Stickers (Avery J8160 3 x 7), 'I can (Answer: No, but typically electricity is the flow of electrons—negative charge. The problem with electrical energy obtained from battery power though, is that battery power eventually runs out and the battery has to be thrown away or recharged. There are two types of electricity, current electricity, which is the kind of electricity that comes from batteries and power points in your home, and static electricity, which is the build up of charge in one place. They are also introduced to the idea of engineers making, controlling and distributing electricity. Sometimes circuits are drawn using special symbols. As necessary, clarify with a simple demo: Have students pour water from one container to another to provide a tangible understanding of the concept of flow. Electricity is made up of atoms. (Slide 3) Topic preview: electricity, conductors, insulators, current, static charge. What do you think will happen to the light bulb as the wire gets longer? The contents of this digital library curriculum were developed by the Renewable Energy Systems Opportunity for Unified Research Collaboration and Education (RESOURCE) project in the College of Engineering under National Science Foundation GK-12 grant no. A model showing that gases are made from matter particles that are too small to see and are moving freely around in space can explain many observations, including the inflation and shape of a balloon and the effects of air on larger particles or objects. Natural objects exist from the very small to the immensely large. ), What if they wanted to protect themselves and you from electrocution? Students gain an understanding of the difference between electrical conductors and insulators, and experience recognizing a conductor by its material properties. Where would you want to put insulators? Electric charge occurs when a net difference in charged particles (such as proton or electrons) exists. It must include a source of electricity, such as a battery. Electricity is present everywhere in our modern lives and engineers who specialize in electricity (electrical engineers) make that possible. Do you agree with this alignment? Note the critical thinking questions/answers included in the notes for slides 8, 10 and 12. you can act as if you are engineers to select the best materials for retaining and releasing electricity. Electricity can be seen in nature in a bolt of lightning. If not, students may need assistance on how analogies work.) Assign students to investigate and research different professions in electricity and/or involving knowledge of electrical systems, as outlined in the Electrical Careers Research Project Handout. Think about safety measures for electricians. (Answer: Anywhere around conductors that you might touch, such as wires that carry electricity. Related Curriculum shows how the document you are currently viewing fits into this hierarchy of curricular materials. Here is a chart to help you to understand the different circuit symbols that are used in when drawing the different components of the circuit. I received an email the other day saying: Love your site! kids, The Low Carbon Partnership: Our
