APS Science 2009 APS Science Curriculum Unit Planner Grade Level/Subject Physics - static electricity Stage 1: Desired Results Enduring Understanding Charged particles will attract or repel each other, depending on the sign of the charges involved, with a force directly related to the size of the charge and inversely proportional to the square of the distance between them. Correlations Unifying Understanding VA SOL PH.12.a NSES (grade level) Grades 9-12, Standard B essay, pages 177-178; Motions and Forces, pages 179-180; Interactions of Energy and Matter, Pages 180-181 AAAS Atlas Essential Questions • What's the best way to shock someone? • What's the best way to avoid being shocked? Knowledge and Skills Students should know: • How to compare and contrast electrical conductors with electrical insulators. • What electric fields are and why they are useful. • How to compare and contrast Coulomb's with Newton's Law of Universal Gravitation? Students should be able to: • Explain the behavior of various electrical phenomena based on the principles of static electricity. • Calculate the force between two or more changed objects; • Calculate the force exerted on a charged object in an electric field; • Draw the electric field in and around various charged objects; 1 APS Science 2009 Stage 2: Assessment Evidence Prior Knowledge and Skills • Static electricity can build up in everyday life and creates sparks under the right circumstances. • Some materials allow electricity to flow easily and some do not. Formative Assessment Summative Assessment • Mid-unit quiz • End of unit cumulative assessment Stage 3: Learning Plan References to Adopted Materials • See textbook correlation below Suggested Investigations • Build a functioning electroscope Outdoor Education Applications • None currently noted Resources Web Sites • http://www.glenbrook.k12.il.us/gbssci/phys/Class/estatics/estaticstoc.html • http://www.shep.net/resources/curricular/physics/P30/Unit2/electroscope.html • http://phet-web.colorado.edu/new/simulations/sims.php?sim=Balloons_and_Static_Electricity • http://ocw.mit.edu/ans7870/8/8.02T/f04/visualizations/electrostatics/40-chargebyinduction/40- chargebyinduction.html • http://www.its.caltech.edu/~phys1/java/phys1/EField/EField.html • www.falstad.com/vector3de Videos • None currently noted Online clips • None currently noted Field Trips • None currently noted 2 APS Science 2009 Other • None currently noted Textbook Correlations Topic Intensified Physics Regular Physics Principles of Physics Electric Force Cutnell & Johnson Hsu, Foundations of Hsu, Physics – A First Physics, Ch 18.2 Physics, Ch 21.1 Course, Ch 15.1 Conductors vs. Cutnell & Johnson Hsu, Foundations of Hsu, Physics – A First Insulators Physics, Ch 18.3 Physics, Ch 21.1 Course, Ch 15.1-2 Methods of Charging Cutnell & Johnson Hsu, Foundations of Hsu, Physics – A First Physics, Ch 18.4 Physics, Ch 21.1 Course, Ch 15.1 Coulomb’s Law Cutnell & Johnson Hsu, Foundations of Hsu, Physics – A First Physics, Ch 18.5, Physics, Ch 21.2 Course, Ch 15.1 18.11 Electric Fields Cutnell & Johnson Hsu, Foundations of Hsu, Physics – A First Physics, Ch 18.6-8 Physics, Ch 21.2 Course, Ch 18.3 3 .
