Static Electricity


A Concept-Builder is an interactive questioning module that presents learners with carefully crafted questions that target various aspects of a concept. Each Concept Builder focuses the learner's attention upon a discrete learning outcome. Questions target that outcome from a variety of angles using multiple difficulty levels or varying activities. The following Concept Builders target concepts in Static Electricity.



Charge and Charging
 
Learning Goal: To use an understanding of the subatomic particle composition of charged and neutral objects in order to identify how an object becomes charged in the manner that it does.




Getting the Hang of Charge
 
Learning Goal: To use information about the interaction of charged and uncharged balloons in order to conclude the type of charge a specific balloon possesses.




Charge Interactions
 
Learning Goal: To use stated information about how four or more charged objects interact with each other in order to determine the type of charge on the objects.




Triboelectric Charging
 
Learning Goal: To use observations from electrostatic tests in order to create a triboelectric series for a collection of materials.





Conductors and Insulators
 
Learning Goal: To use an understanding of conductors and insulators to predict the extent to which charge will flow when a collection of objects is touched to the ground or another charged object.




Polarization
 
Learning Goal: To understand that polarization involves a separation of charge and to explain which way electrons move and how charge distributes itself during a polarization process.




Charging by Induction
 
Learning Goal: To describe - in terms of particle movement - the two-step process of charging by induction.




Coulombs Law 
 
Learning Goal: To use Coulomb's law of electric force to predict the effect of varying charge and varying separation distance upon the electrostatic force between two objects.
 




Electric Field
 
Learning Goal:To use the relationship between Source Charge, Distance, and Electric Field Strength (E) to rank the E values for three locations, to quantitatively compare E values, and to calculate the E value at one location if given its value at another location.




Electric Field Intensity
 
Learning Goal: To use the electric field equations to predict the effect that variations in Q, q, and d would have upon electric field intensity.
