Travoltage Remote lab This lesson is designed for a student working remotely This lab uses the Balloons and Static Electricity and John Travoltage Remote lab simulation from PhET Interactive Simulations at University of Colorado Boulder under the CC BY 4 0 license https phet colorado edu sims html balloons and static electricity latest balloons and static electricity en htmlhttps phet colorado edu sims html john travoltage latest john travoltage en htmlLearning Goals Students will be able to describe and draw models for common static electricity concepts transfer of charge induction attraction repulsion and grounding Develop your understanding 1 Open Balloons and Static Electricity then explore to develop your own ideas about electricalcharge Describe several of your experiments and your observation with captured images from the simulation Hint rub the balloon with the sweater and see how it interacts with other objects such as another balloon wall a Rubbing the balloon against the sweater makes the balloon to get all of the sweater s negative charges Once the balloon gets all of the sweaters negative charges it gets attracted to the sweater and every time the balloon gets loose it tends to move toward the sweater 3 31 20 Loeblein https phet colorado edu en contributions view 2847 page1 This study source was downloaded by 100000842653451 from CourseHero

charges to move away from the balloon s negative charges Once the wall gets removed the balloon moves toward the sweater 2 Open John Travoltage then explore to develop your own ideas about electrical

coursehero com file 70382244 Lab5 1docx Describe several of your experiments and your observation with captured images from the simulation a According to the simulation whenever John walks he attracts electrons from the floor As long he does not have any electrons in his body he can touch a charged object and won t get shocked b Whenever there are electrons in Johns body he will get shocked if he even comes close to a charged object and touches the floor or something with his feet If John does not touch anything but the charged object he does not get shocked 3 31 20 Loeblein https phet

Test your understanding Without using the simulations predict the answers to these questions then usethe simulation to check your ideas Question 1 When the balloon is rubbed on the sweater what might happen What do you predict for the answer Some negative charges in the seater will move onto the balloon Describe an experiment and include images from the simulation that supports your answer 3 31 20

70382244 Lab5 1docx According to the image whenever we rub a balloon on a sweater the sweater transfers some of its negative charges to the balloon Question 2 What do you think will happen when the balloon is moved closer to the wall 3 31 20 Loeblein https phet colorado edu en contributions view 2847 page5 This study source was downloaded by 100000842653451 from CourseHero com on 03 03 2022 06 19 37 GMT 06 00 https www coursehero com file 70382244 Lab5 1docx What do you predict for the answer Some positive charges in the wall will move towards the balloon Describe an experiment and include images from the simulation that supports your answer As we can see in the experiment the negative charges in the wall move away from the negative charges in the balloon and thus the positive charges in the wall move closer to the negative charges in the balloon Question 3 What do you think the balloons will do 3 31 20 Loeblein https phet colorado edu en contributions view 2847 page6 This study

move away from each other Describe an experiment and include images from the simulation that supports your answer Once both of the balloons receive the negative charges from the sweater both of them tend to move towards the sweater but whenever the balloons are put beside one another they tend to move away from one another Question 4 What might happen to the charge on the man when he touches the door knob 3 31 20 Loeblein https phet colorado edu en contributions view 2847 page7 This study source was downloaded by 100000842653451 from CourseHero com on 03 03 2022 06 19 37 GMT 06 00 https www
