3. Statics$100 The cause of all electricalphenomena. What is the movement of electrons ?

4. Statics$200 It’s what the word “static” really means. What is “not moving” ?

5. Statics$300It is the reason used when using the electrostatic series to describe the strength of a charge. What is “the greater the separation, the greater the charge” ?

6. Statics$400 A type of material that holds a charge rather than conducts a charge. What is an “insulator” ?

7. Statics$500 Famous Philadelphian who used a form of the Leyden Jar to prove lightning was static electricity. Who is “Benjamin Franklin”?

8. Electroscope$100 The property that enables the electroscope to “hold charges” and not “ground them”. What is ”insulation” ?

9. Electroscope$200 Name of an instrument used to detect static charge. What is”the electrostatic pendulum or electroscope?

10. Electroscope$300 It’s where the electrons are in the electroscope, if a negative rod is brought near the collecting sphere. What is “in the leaves” ?

11. Electroscope$400 The charge found on the leaves when a negative rod is used to charge an electroscope by induction with a ground. What is “positive charge” ?

12. Electroscope$500 What one electron might say to another electron. What is “you repel me, or get away from me” ?

13. Electrophorus $100 The reason the electrophorus is held by the styrofoam cup. What is “to prevent grounding of the charge” ?

14. Electrophorus $200 Term used to describe a separation of charges. What is “neutral dipolar” ?

15. Electrophorus$300It’s why the electrophorus styrofoam sheet only has to be charged once. What is “it never gets grounded because it is never touched” ?

16. Electrophorus$400 He invented the electrophorus in 1775. Who is “Alessandro Volta” ?

17. Electrophorus $500 It is the charge on the entire pie plate of the electrophorus when placed on a sheet of acetate rubbed with a plastic bag. What is ”neutraldipolar” ?

18. Leyden Jar$100 It is the reason why we hold a leyden jar by the foil when charging it. What is “to ground the negative charges on the foil” ?

19. Leyden Jar $200 The charge on the foil of a Leyden jar with negatively charged water. What is “Positive”?

20. Leyden Jar$300 It is how a Leyden Jar can be positively charged using an electrophorus and negative styrofoam. What is “touch nail to rim while off the styrofoam” ?

21. Leyden Jar$400 The charge on the outside wall of a film canister of a leyden jar with negatively charged water. What is “negative” ?

22. Leyden Jar$500 It is the electrical name given to a leyden jar. What is a “capacitor”?

23. Van de graaf$100 It is the force responsible for all static charges. What is “friction”?

24. Van de graaf$200 It is the rule of charge why a person’s hair rises while touching a Van der Graaf Generator. What is “like charges repel” ?

25. Van de Graaf$300 Name the part of the Van de Graaf generator that prevents charge from being grounded. What is the“ insulated support” ?

26. Van de Graaf $400 Given rule of charge that explains why Van de Graaf shocks humans. What is “neutral objects are attracted to charged objects” ?

27. Van de Graaf$500 It’s where the electrons collect on the Van der Graaf generator. What is ”the collecting sphere”?
