Georgia Performance Standards Framework for Science – Grade 5 Unit One Organizer: Fifth Grade Electricity and Magnetism (9 Weeks) OVERVIEW: Students will carry out investigations to become familiar with the pushes and pulls of magnets and static electricity. The unit will give students a basic understanding to determine what conditions produce a magnetic field such as an electromagnet and what conditions induce electric currents using simple circuits. Although electricity is the movement of electrons from one place to another, at this grade level there is no emphasis on electrons or atomic structure. Explaining positive and negative charges as they attract and repel will help students gain a basic understanding of the relationship between magnetism and electricity. Batteries are used as energy sources and flashlight bulbs obtain energy to become the energy receivers. STANDARDS ADDRESSED IN THIS UNIT Focus Standards: S5P3. Students will investigate the electricity, magnetism, and their relationship. a. Investigate static electricity. b. Determine the necessary components for completing an electric circuit. c. Investigate common materials to determine if they are insulators or conductors of electricity. d. Compare a bar magnet to an electromagnet. S5P1 Students will verify that an object is the sum of its parts. STANDARDS ADDRESSED IN THIS UNIT Supporting Standards: S5CS3. Students will use tools and instruments for observing, measuring, and manipulating objects in scientific activities. a. Choose appropriate common materials for making simple mechanical constructions and repairing things. b. Measure and mix dry and liquid materials in prescribed amounts, exercising reasonable safety. c. Use computers, cameras and recording devices for capturing information. d. Identify and practice accepted safety procedures in manipulating science materials and equipment.

Students will communicate scientific ideas and activities clearly. a. Write instructions that others can follow in carrying out a scientific procedure. b. Make sketches to aid in explaining scientific procedures or ideas. c. Use numerical data in describing and comparing objects and events. d. Locate scientific information in reference books, back issues of newspapers and magazines, CD-ROMs, and computer databases. S5CS6. Students will question scientific claims and arguments effectively. a. Support statements with facts found in books, articles, and databases, and identify the sources used. b. Identify when comparisons might not be fair because some conditions are different. S5CS8. Students will understand important features of the process of scientific inquiry. Students will apply the following to inquiry learning practices: a. Scientific investigations may take many different forms, including observing what things are like or what is happening somewhere, collecting specimens for analysis, and doing experiments. b. Clear and active communication is an essential part of doing science. It enables scientists to inform others about their work, expose their ideas to criticism by other scientists, and stay informed about scientific discoveries around the world. c. Scientists use technology to increase their power to observe things and to measure and compare things accurately. d. Science involves many different kinds of work and engages men and women of all ages and backgrounds. ENDURING UNDERSTANDINGS Magnets can be used to generate electricity. Some materials are good conductors while others are good insulators. Like charges repel and unlike charges attract. Motion is produced from electric energy. Resistors change some currents into heat or light Electric currents are useful.

Why do things cling? 2. Why do magnets repel and attract? 3. How are electricity and magnetism connected? 4. How does a basic electric circuit work? 5. How are conductors and insulators different? 6. What are the uses of electricity and magnetism in everyday life? MISCONCEPTIONS Electricity is a form of energy. PROPER CONCEPTIONS Electricity is the effect of the apparent motion by an electric current. The electric energy in a circuit flows in a circle. When you connect a light bulb to a battery, electrical energy moves from the battery to the bulb. This is a one-way flow. Two kinds of electricity are “static” and “current”. Static and current are two ways in which electrical charges can behave. Current is produced by the apparent motion of electrons along a conductor. The stuff that flows through wires is called “electric current.” An electric current is a flow of charge. Static electricity is caused by friction. Static electricity appears when 2 dissimilar insulating materials are placed into intimate contact and then separated. Insulators and Conductors do the same job. Some materials are conductors and some materials are insulators. Conductors are materials that allow electricity to flow easily. We use these materials in electrical circuits. Insulators don't allow electricity to flow easily and we use these materials to protect ourselves. An electromagnet must have an iron nail. An electromagnet is wire coiled around a cylinder such as a nail. It may or may not have an iron core. Batteries have electricity inside. A battery or generator is like your heart: it moves blood, but it does Georgia Department of Education Kathy Cox, State Superintendent of Schools Electricity and Magnetism Unit Grade 5 April 16, 2007 Page 3 of 6 Copyright 2007 © All Rights Reserved One Stop Shop For Educators Georgia Performance Standards Framework for Science – Grade 5 not create blood. Electric currents in copper wires are a flow of electrons, but these electrons are not supplied by batteries. Generators do not 'generate' them. Instead the electrons come from the wire. In copper wire, copper atoms supply the flowing electrons. The electrons in a circuit were already there before the battery was connected. They were even there before the copper was mined and made into wires! Batteries and generators do not create these electrons, they merely pump them, and the electrons act like a preexisting fluid which is always found within all wires. Because of the abstract nature of electricity we are only dealing with the very basic misconceptions. You could come in contact with many more misconceptions.

Role: An 1800’s pioneer. Audience: Peers Scenario: You are a pioneer in the late 1800s and live in a log cabin on the plains. Electricity has now become available to the region. You have read newspaper articles about an inventor named Edison and his new appliances for the home. You will work in small groups to discuss the pros and cons of this technology, and figure out how to safely modify your log cabin to incorporate electricity. Product: Your group will design and construct a log cabin (shoe box) including the new technology of electricity (simple circuits). The group will design a blueprint to scale including a diagram of electrical wiring. Measurements must be accurate for the ordering of materials, such as wire, bulbs, and batteries. Materials will be ordered using the correct forms from the class supply clerk. Completed designs will demonstrate the use of electric circuits to light the cabin safely.
