1. Static Electricity

2. Matter and Energy Review
Before we learn about static electricity, we need to do a little review of some chemistry
___________________ is anything that has mass and takes up space
___________________ is anything that can exert (push) a force onto another object

3. Matter Review Matter is made of ______________
Atoms are made of protons, neutrons, and electrons
Electrons are _____________________from the nucleus

4. Electrons
Because electrons are so far away, they have the ________________________ ___________________________
When electrons jump from atom to atom it is called a _________________ _________________
Important to remember – __________ _______________________________

5. Electrons and Charge
Atoms usually have the ____ _____________________ of protons (positive) and electrons (negative)
If you think of this like a balance, it means the ______ in atoms are usually _____________________
The _____________________
Positives and Negatives balance and make an overall charge of _______________

6. Electrons and Charge
However, if electrons ‘__________’ to a different atom, it leaves a _________
Now there are __________ ______________________
This leaves an ___________ _______________________
Losing electrons leaves an overall __________ charge

7. Electrons and Charge
If electrons ‘jump’ onto an atom, it will end up with more electrons
_________________means more ___________ charges
A higher number of negative charges leaves an overall ___________________ charge
Gaining electrons leaves an overall _____________charge

8. Moving Electrons
One of the easiest ways to create a separation of charges is to _______________________________
When materials are in _________________, the electrons can ‘_________________’ from one material to another
By adding a little energy, it helps the electrons jump

9. Static Electricity
When there is a separation of charges, it is called _______________________
Static Electricity is ________ _______________________ _______________________
These charges stay there until they are ____________

10. Moving Electrons
If you rub 2 materials together, one object will _________________________________
It will get a ___________________ charge
The other object will ____________________
It will get a ____________ charge

11. Holding Electrons
When you rub 2 materials together, some will __________________________________and are more likely to _____________________
Become ___________________________
Some materials ______________________ and are more likely to become ___________ _______________

12. Electrostatic Series
We list objects on an _____________ _____________________ to show how well objects will _____________
The ___________________ it is on the list, the greater the tendency to _____________________________
The __________________ on the list, the greater the tendency to ____________________________

13. Electrostatic Series
If you are going to rub 2 objects together, you can use an electrostatic series to see which has a positive charge and which has a negative charge
The higher object on the series becomes positive
The lower object on the series becomes negative

14. Electrostatic Series
The further away objects are on the series, the greater the separation of charges
The greater the separation of charges, the more static electricity is created
Examples
Cotton and Vinyl are rubbed together, which becomes positive? Negative?
Which creates more static electricity, wool and acetate or nylon and polyester?

15. Van de Graaff Generator
A Van de Graaff Generator is a ____________________________
It works by rubbing 2 objects together
These objects create static electricity and generate ___________________________
They are _____________ however

16. Van de Graaff Generator
It uses a motor to run a _______________________
The rubber belt moves and rubs against a ___________________.
The brush transfers the charge to the _______________________

17. Van de Graaff Generator
What charge does the dome have?
The rubber belt transfers its charge to a regulator
What charge does the belt have?

18. Van de Graaff Generator
The dome takes on an overall _________________
The regulator builds up an overall _________________
This charge can be ______________________ if you touch the dome

19. Volunteers?
If you want to try out the Van de Graaff, we will try making a chain of people to see how the charge is transferred
If you have heart problems or a pacemaker, please do not participate
Remove your cell phones, iPods, and electronics just in case the static electricity discharges into your devices and wrecks it
You do not HAVE to participate but I guarantee that you will live through this

20. Why did that happen? Like I had mentioned, electricity _____________
_________________________________
Electricity basically discharges to ___________ ______________________________________
This is done by making electrons flow _____________________ the positive charge
For electrons to flow, we need a place to store ______________________________________

21. Grounding
Luckily the ______________ has a huge storage of lots of positive and negative charges
If we make a ___________________, it causes electrons to flow to the positive charge
This is called ____________________
This is because the _______________ ______________________________
We often feel this as a ____________

22. Grounding
One of the most spectacular displays of grounding is _______________________
Lightning is a build up of ____________________________ that is grounded by lightning

23. Clouds are made of water vapor
If the water vapour swirls around and rubs against each other enough, it can cause a build up of negative charges in a cloud
If the charge is built up enough, it can force an area on the ground to become positively charged
Once there is enough charge built up, the build up of electrons shoots down from the cloud into the positive in the ground.
This grounds the cloud and forms lightning

24. Static Shocks
Although static shocks are nothing more than annoying in our daily lives, they have other implications
Jet planes
Car refueling
Electronics manufacturers
Space Travel
Cracking Rubber
