This Concept Map, created with IHMC CmapTools, has information related to: Understanding Electric Force, A student that 'understands' electric force has addressed common misconceptions M: Charges are 'used up' (ie Not conserved), M: think of charge as an 'object' rather than a property of matter. Charge is a substance that can be 'painted on' matter. Teachers must avoid refering to 'two charges' rather than 'two charged objects', A student that 'understands' electric force has addressed common misconceptions M: Insulators cannot be charged, A student that 'understands' electric force has addressed common misconceptions M: There is a fundamental reason why electrons are 'negative', A student that 'understands' electric force has addressed common misconceptions M: neutral is a third type of charge, M: neutral is a third type of charge for example M: attributing attraction via induction to a neutral object being attracted because 'opposites attract', A student that 'understands' electric force is able to distinguish between an object (insulator/conductor) and its charge state (charged/neutral), A student that 'understands' electric force is able to distinguish between charge and current (motion of charge), A student that 'understands' electric force is able to describe the structure or atomic properties of solids. (is able to explain what neutral, non-neutral, and charged mean at the atomic level), A student that 'understands' electric force has addressed common misconceptions M: current is 'used up' as it flows through a circuit, A student that 'understands' electric force has addressed common misconceptions M: batteries are a source of constant current. The same battery will provide the same current to any circuit, A student that 'understands' electric force has addressed common misconceptions M: A postively charged object has recieved an excess of protons (ie protons are as mobile as electrons), A student that 'understands' electric force has addressed common misconceptions M: think of charge as an 'object' rather than a property of matter. Charge is a substance that can be 'painted on' matter.
