§11.1 - Static Electricity
Science - TTO2

Slide 1 - Slide

Learning Goals
  • Describe simple experiments to show how to produce and    detect electric charge. 
  • State that there are positive and negative charges. 
  • State that unlike charges attract each other and like charges repel each other. 
  • - State that charge is measured Coulombs

Slide 2 - Slide

Do you know John Travolta?!
You might know him from this song...


You don't have to watch the full clip ;-)

Slide 3 - Slide

Well... it's time to meet his cousin: 



Click the link on the next slide.
Try to move John's leg/arm around and see what happens!
If you have seen enough, continue with the next slide.

Did you see what happend?
Yes, John got zapped by the doorknob!
But how is this possible?

Read p. 154 and 155 in your book.

Try to explain why John got zapped in your own words. 
Use the question box on the next slide to fill in your answer.

Slide 6 - Slide

Explain in you own words why John got zapped by the doorknob.

Slide 7 - Open question

Time for a video!

All matter made out of atoms

Slide 10 - Slide

Inside an atom:

Protons (postively charged)
Neutrons (neutrally charged)
Electrons (negatively charged)

Slide 11 - Slide

Inside an atom:
  •  An uncharged atom has an equal amount of protons and electrons. 
  • Electrons move about in the space around the nucleus. Therefore, they can easily jump from one atom to another one.
  • Protons can't move, since they can't leave the nucleus.
  • If an atom receives or gives away electrons, the atom becomes charged.

Slide 12 - Slide

Charge:
  • Charge is measured in Coulombs. 
  • Atoms/objects that receive electrons, become negatively charged.
  • Atoms/objects that give away electrons become positively charged. 
  • Whether an object becomes postively or negatively charged depends on the two materials that rub together. 

Slide 13 - Slide

Charge:

Like charges repel each other



Unlike charges attract each other
