1

How is static electricity transferred when sticking a charged balloon to a wall?

Induction

2

How is static electricity transferred when touching a charged cloth to a piece of metal

Conduction

3

The buildup of charges on an object is called________.

Static electricity

4

What law states that charges are not created or destroyed they are transferred.

Conservation of charge

5

The transfer of charge from one object to another by rubbing is called ____________.

Friction

6

What instrument can detect electric charge?

Electroscope

7

The loss of static electricity as electric charges move off an object is called __________.

Static discharge

8

What is the movement of electrons from one part of an object to another part, caused by the electric field of another object, without the two objects touching called?

Induction

9

What is the transfer of charge when electrons move from a charged object to another object by direct contact called

Conduction

10

Placing your hands on the Van de Graaff generator is that friction induction or conduction?

Conduction

11

Friction induction or conduction ?
when using a charge balloon to pick up a small piece of paper

Induction

12

When rubbing plastic wrap on a balloon, is it friction induction or conduction?

Friction

13

What did you observe happening to the butterfly wings when you came near them with the charged balloon?

The wings were attracted to the balloon so they came up and touch the balloon

14

Why did the wings move?
explain what happened to the subatomic particle's in the wings that cause this to occur

The wings were attracted to the balloon, the subatomic particles rearranged to touch the balloon

15

Explain how the balloon became charged by friction?

We were of the balloon on our shirt and the electrons jumped to the balloon and left our shirt positive

16

What type of charge does the balloon have?

A negative charge

17

What other lab or demonstration show this method of charging?

The salt and pepper lab

18

What are three ways static electricity can be transferred?

Friction conduction and induction

19

Does static electricity move?

No static means not moving

20

Which sentence explains why there is no overall electric charge in a neutral object?
A. In the objects atoms, each positive charged is balanced by a negative charge
B. The objects atoms contain no charged particles
C. The positive charges are attracted to other positive charges

A

21

How can an object become charged?

An object becomes charged by friction, for example a balloon is rubbed on wool, now the wall is + and the balloon -
is gaining or losing electrons

22

The buildup of charges on an object is called ____________.

Static electricity

23

If an object gains electrons what will be its overall charge?

Negative

24

What is anything that takes up space and has mass called?

Matter

25

What tiny particles are all matter made up of?

Atoms

26

What charges does each atom contain?

Electrons, protons and neutrons

27

What charges do electrons have?

Negative

28

What charges do protons have?

Positive

29

What charges do neutrons have?

Neutral charge

30

Where are protons and neutrons found in an atom?

In the central core or nucleus

31

If electrons are not found in the nucleus where are they located?

They orbit around the nucleus

32

Explain why most objects are considered electrically balanced.

They are electrically balanced because they have the same number of electrons and protons

33

If an object loses electrons when it is rubbed, it is said to have a _________ charge because it has more protons

Positive

34

Like charges or charges that are the same, occur when two objects both became __________ or _________ charged

Positive and negative

35

When one object becomes positively charged and the other becomes negatively charged they are considered to be _________ charges

Unlike

36

What are three methods in which charges are transferred?

Friction, conduction and induction

37

True or false?
An electric field extends outward from every charged particle

True

38

Because of an electrical field, charged particles that are ___________ would be pulled together

Different or opposite

39

What instrument has two thin metal leaves and is used to detect an electrical charge?

Electroscope

40

Cellophane was stuck on the wall then wool was rubbed on it then taken off and it repel but when she put her arm in the middle it attracted. Name the method of charging

Friction

41

The balloon was rubbed on hair then the balloon was taken away and the hair was attracted to the balloon and was sticking up to touch the balloon. Name the method of charging

Friction

42

The ripped paper started stacking up to touch the balloon because it was attractive. Name the method of charging

Induction

43

The comb was near the water and was curving closer to the comb to be attracted to it. Name the method of charging
