What are the two types of charges?
Positive charge and negative charge
Immunity!
Your team will receive one immunity buff from deduction, blocking, and stealing.
If an object gained electrons, what charge does it have?
Negative
What is an uncharged object called?
Neutral
If an object lost electrons, what charge does it have?
Positive
Complete the sentence:
An object that has a positive charge has more _______ particles, and less ________ particles.
Positively charged;
Negatively charged
What is the force that acts on charged particles?
Electric force
Deduction!
Choose a team to deduct 200 points. If all the other teams have immunity, your team will receive the deduction.
Complete the sentence:
An object that has a negative charge has more _______ particles, and less _______ particles.
Negatively charged; Positively charged
Steal!
Steal 200 points from another team.
Block a team!
Choose one team to block. A blocked team will not be able to answer in one turn. A team with immunity will not be blocked.
Complete the sentence:
An electrical charge is created when electrons are ________.
transferred to or removed from an object
Why does an object becomes negatively charged when it gains electrons?
It has more negatively charged particles
What refers to the process of charging objects by rubbing them together?
Charging by friction
Why does an object that losses electrons becomes positively charged?
It has more positively charged particles
What happens to the electrons when you rub two objects together?
The electrons are transferred to another object.
Blocked!
Your team has been blocked! Sing a short song to receive immunity.
If a negatively charged balloon was placed next to another negatively charged balloon, what would happen?
The balloons will repel each other because they have similar charges.
If a negatively charged balloon was placed next to a positively charged object, what would happen?
The two objects will be attracted to each other because they have different charges.
Complete the sentence:
The Electrostatic Law states that _________.
like charges repel and unlike charges attract.
What is the difference between positive charge, negative charge, and neutral charge.
Positive charge= more positively charged particles
Negative charge= more negatively charged particles
Neutral= equal
Complete the sentence:
The Law of Conservation of Charge states that________.
charges cannot be created nor destroyed, but can be transferred from one material to another.
Explain the Law of Conservation of Charge.
Charges can neither be created nor destroyed. It means that when the object lose electrons, the electrons does not disappear or gets destroyed. It is transferred to another object.
Challenge!
Choose one team to challenge. Ask them one question about the lesson. If they answered correctly, both teams will receive 500 points. If they answered incorrectly, your team will receive 1000 points.
Explain how an object gets charged by friction.
When rubbing two objects together, some of the electrons from one object are transferred to the other object. The object that gains electrons become negatively charged, while the object that lost the electrons become positively charged.
