Science Lesson 1

What is Static Electricity?

QuestionAnswer
What do opposite charges do? Opposite charges attract or pull toward each other.
How can a plastic ruler get a positive charge? By losing negative charges.
If you rub a balloon on a wool sweater the balloon will stick to wool. What causes this to happen? Static electricity
Electric field The area around electric charges where electric forces can act.The space in which electric forces act. Both negative and positive.
Electric Charge A basic property of the tiny particles that make up matter. Electric charge can be positive or negative. It happens when you have either more positive than negative charges (Positive Charge) or vice versa (more negative so you have a negative charge).
Static Electricity The buildup of electric charges in one place.
Electricity It is used to describe some kinds of energy.
Neutral Positive and Negative charges cancel each other when matter has a balance of charges.
Repel to push away from something.
When can you tell 2 balloons attach each other? When 1 balloon pulls away.
Positively charged When 2 balloons push away from each other.
Investigation: What can you infer about the interaction between the car seat, the car door and Nadine when you she gets shocked. Static electricity is generated when Nadine rubs agaisnt the fabric of the car seat. The shock is the rebalancing of electric charges.
What is a cause and effect related to static electricity with respect to clothes in a dryer? As the clothes rotate in the dryer, this causes the clothes to rub against each other and the charges move around. The effect is that the clothes will stick together since opposite charges attract each other.
Name one way a balloon could become negatively charges. A balloon could become negatively charged by rubbing against a piece of wool.
Name the 2 kinds of charges. Negative and positive
What do charges that are the same do? The charges repel or push away from each other.
How can you separate charges on some objects? By rubbing them together. Rubbing pulls negative particles off one object and onto the other.
What charges do not move? Positive charges. Only negative charges can move from one object to the next.
What can you infer if you have a piece of wool next to a balloon and nothing happens? Neither object has an electric charge. The number of positive and negative charges on the balloon and on the wool are equal. Both objects are neutral.
What happens when you walk across a carpet and get shocked? Negative charges move from the carpet to your bodt. Your body becomes negatively charged. Touching the door knob gave the charges a place to go. They jumped on the door knob in a spark. The charges became balanced again.
If 2 charged objects attract each other, what type of charges must they have? Opposite charges.
How do you separate charges? 1. rub together 2 objects and 2. bring the charged objects to a nuetral object
Extra facts about Electric Charges? 1. Both negative and positive. Electric charges have an electric field around them. 2. The push and pull between objects that have different charges. 3. An electric force is caused by the electric by field around the charge.
