Lafayette Parish School System 2013-2014 Curriculum Map Physical Science: Unit 2b: Energy: Electricity and Magnetism Time Frame: 4 weeks—November 11 – December 13, 2013 Unit Description and Student Understandings: This unit thoroughly examines the properties of static electricity, electric circuits, magnetic fields, and the relationship between electricity and magnetism. Incorporating inquiry processses, students will examine and identify propeties and connections between the phenomena of electricity and magnetism. In addition, students will investigate the production of static electricity, construct electrical circuits, map magnetic fields, and build an electromagnet. Using inquiry processes, students will demonstrate their understanding of simple and compound machines and will describe the relationships among energy, work, and power. Students will identify and examine differences between potential and kinetic energy, and also analyze various energy transformations. Guiding Questions: 1. 2. 3. 4. 5. 6. Can students create and define static electricity? Can students construct a complete circuit? Can students differentiate between parallel and series circuits? Can students trace the flow of electrical energy in a diagram of a complete circuit? Can students describe a magnetic field? Can students describe a relationship between electricity and magnetism? Key Concepts: Like electric charges repel each other, and unlike charges attract each other. An electric current is a flow of electric charge Electrical devices can be placed into series circuits as well as parallel circuits A magnet is surrounded by a magnetic field that exerts a force on magnetic materials An electric current in a wire is surrounded by a magnetic field A changing magnetic field produces an electric current in a wire loop Vocabulary List: Static electricity, law of conservation of charge, electric field, conductor, insulator, charging by contact, charging by induction, electroscope, electric current, voltage difference, electric circuit, resistance, Ohm’s law, series circuit, parallel circuit, electrical power, magnetism, magnetic field, magnetic pole, magnetic domain, electromagnetic force, solenoid, electromagnetism, galvanometer, electric motor, electromagnetic induction, generator, turbine, direct current (DC), alternating current (AC), transformer, 1 Physical Science 2013--2014 Lafayette Parish School System 2013-2014 Curriculum Map Physical Science: Unit 2b: Energy: Electricity and Magnetism Time Frame: 4 weeks—November 11 – December 13, 2013 GLEs CCSS Literacy Standards NGSS Practices Instructional Strategies (Activity directions are found in the Unit folder in Environmental Science documents on LPSS Blackboard) SI-5, E Glencoe Textbook Correlations—Unit 2- Utilize mathematics, organizational tools, and graphing skills to solve problems (SI-H-A3) Chapter 6---Electricity—pp. 168—199 Chapter—7-Magnetism and its Uses pp. 200--231 Differentiation (Enrichment/Remediation Strategies) vocabulary self-awareness chart (view literacy strategy descriptions) science learning logs (view literacy strategy descriptions).
