Polarization - Directions
Using the Polarization Concept Builder is quite simple. There are three different activities, each with a different emphasis. In each activity you will be presented with a question that you will have to answer.
In the first activity - Separation of Charge - you will be asked to determine how charge polarizes itself on a neutral conducting object when a charged object is brought near it. You will tap on the neutral object to toggle through the options for how charge becomes polarized. You must also identify the object as being "positively-charged", "negatively-charged", "electrically neutral", or "polarized"; you can choose more than one answer. Once you have completed these two tasks, a Check Answer button appears. Once you are satisfied with your answers, tap on the Check Answer button. Your answer will be evaluated and your Progress Report will be updated.
In the second activity - Particle Flow - you must show how charge polarizes itself on a collection of three conducting and insulating blocks. You so do by tapping on the Charge Distribution button in order to toggle through the six options. You must also identify the manner in which charge flows in order to cause such a separation of charge. This is done by tapping on the Particle Movement button. Once you have done both of these tasks, a Check Answer button appears. Once you are satisfied with your answers, tap on the Check Answer button. Your answer will be evaluated and your Progress Report will be updated.
In the third activity - Induction - an induction charging process is described and animated. You can tap the Replay button to view the animation as many times as needed. You will have to identify the resulting charge of the object. You also have to explain how the object becomes charged in terms of particle movement. You can tap on the diagram at the bottom right in order to toggle through the eight options. Once you have done both of these tasks, a Check Answer button appears. Once you are satisfied with your answers, tap on the Check Answer button. Your answer will be evaluated and your Progress Report will be updated.
Your goal is to earn "Stars" and to complete one or more activities. Stars are earned when you show success on a particular question. Once you show success on all the questions for a particular activity, you will earn the Trophy for that activity.
