Department: Science Understanding by Design Course: Phys-Electricity Standard(s): 12.11.65 Understand that a magnetic field is generated around an electrical current and that the motion of a conducting wire through a magnetic field generates a current through it. Understand that in some substances, such as metals, electrons flow easily, whereas in insulating materials such as glass they can hardly flow at all. Semiconducting materials have intermediate behavior. At very low temperatures, some materials offer no resistance to the flow of electrons and become superconductors. Stage 1: Desired Results Understandings Apply and identify concepts of circuits Fundamentals - Students will know the definitions of electric current, voltage and voltage sources, resistance, electric shock, DC/AC current, and electrical power as well as be able to use them correctly in physical systems. Students will conceptually understand Ohm’s Law and use the following equations to solve simple problems. V=IR Students will identify and distinguish between parallel and series circuits. Students will draw and identify the components of a schematic diagram and calculate the effective resistance of simple series or parallel circuits. S T A G E 1 Physics - Students will know the definitions of electric current, voltage and voltage sources, resistance, electric shock, DC/AC current, and electrical power as well as be able to use them correctly in physical systems. Students will conceptually and mathematically understand Ohm’s Law and use the following equations to solve problems. V=IR Students will identify and distinguish between parallel and series circuits. Students will draw and identify the components of a schematic diagram and calculate the effective resistance of series or parallel circuits. Students will understand and calculate how electrical energy is transmitted through the power grid. Honors/AP - Students will know the definitions of electric current, voltage and voltage sources, resistance, electric shock, DC/AC current, and electrical power as well as be able to use them correctly in physical systems. Students will conceptually and mathematically understand Ohm’s Law and use the following equations to solve problems, potentially involving multiple steps and calculations. Students will identify and distinguish between parallel and series circuits. Students will draw and identify the components of a schematic diagram and calculate the effective resistance of complex series or parallel circuits. Students will understand and calculate how electrical energy is transmitted through the power grid. Essential Questions How does electricity work? Knowledge & Skill See Knowledge & Skills Sheet.
