Contents Home Overview Organizing Your Lab Lesson 1 A Simple Electric Circuit Lesson 2 A Series Circuit Lesson 3 A Parallel Circuit Lesson 4 Cells & Batteries Sources in Series and Parallel Lesson 5 Resistance - Ohm’s Law Lesson 6 Canadian Electricity Alternatives Course Facilitator & FAQ's Expectations Acknowledgements		Overview These activities teach the basic concepts involved in current electricity, how they relate to electrical circuits (Ohm’s Law), and the practical setup of these circuits. The problem about understanding Electricity, is that it’s effects happen too quickly and can’t be directly seen. Because of this, we make use of models to help us understand it. The large group model used in this activity is called the Wooden Block model. Other models and demonstrations are included in these notes in order to strengthen understanding and increase perspective. Before you begin: What the students need to know. Use of models to explain unobservable phenomena Basic Atomic theory i.e. Familiar with: subatomic particles of electron, Neutron, Proton, Nucleus Static electric law of attraction Electrons are free to move in conducting solids one Coulomb = 6.24 X 10¹⁸ electrons (or simply, a definite, large number of electrons.) Information Concerning Downloadable Student Notes Arial Fonts are used to improve the quality of photocopied notes for the students Graphic exercises are used to help student avoid many practical problems when they move toward the wiring exercises. The diagrams are designed to create circuit pictures from schematic diagrams in order to practise wiring real circuits from schematic diagrams review relative positions of circuit parts between schematic and circuit pictures. introduce topographical problems that develop when its impossible to physically place a meter in correct relative position predict what meter readings should be so that the student can self-discover wiring errors introduce common wiring errors in order to help students develop their own troubleshooting heuristics
