Question

scholastic study jam: electricity
name

1. what causes electricity?

a) the nucleus of an atom
b) moving neutrons
c) moving protons
d) moving electrons

1. what type of charge do electrons have?

a) negative charge
b) positive charge
c) no charge
d) atomic charge

1. what reaction can you expect when electrons hop from the atoms in one object to the atoms in another?

a) a thermal reaction
b) an electric reaction
c) a solar reaction
d) a nuclear reaction

1. which of the following is an example of electricity that is created by nature?

a) wind turbines
b) socks in a dryer
c) water dams
d) lightning

1. what happens when you walk across a room and your shoes rub against the carpet?

a) protons move from your shoes to the carpet, giving the carpet a positive charge.
b) your shoes stick to the carpet.
c) electrons hop from the carpet to your shoes, creating static electricity.
d) nothing happens

1. what causes your hair to stand up when you take off a winter hat?

a) negative charges repelling each other
b) negative charges attracting the positive charges
c) positive charges attracting each other
d) negative charges repelling the positive charges

1. what type of electricity occurs when you rub a balloon on your sweater?

a) neutral electricity
b) static electricity
c) hydro electricity
d) thermal electricity

Explanation:

1. Electricity is caused by moving electrons. Protons and neutrons are in the nucleus and don't move to create electricity.
2. Electrons have a negative charge. Protons have a positive charge and neutrons have no charge.
3. When electrons hop between atoms of different objects, it's an electric - related phenomenon, creating an electric reaction.
4. Lightning is a natural form of electricity. Wind turbines, water dams are human - made electricity generation methods, and socks in a dryer show static electricity but are not natural large - scale electricity examples.
5. When shoes rub against the carpet, electrons hop from the carpet to the shoes, creating static electricity. Protons don't move in this context.
6. When taking off a winter hat, negative charges (electrons) on hair repel each other, making hair stand up.
7. Rubbing a balloon on a sweater creates static electricity due to the transfer of electrons.

Answer:

1. d) moving electrons
2. a) negative charge
3. b) an electric reaction
4. d) lightning
5. c) Electrons hop from the carpet to your shoes, creating static electricity.
6. a) negative charges repelling each other
7. b) static electricity
