Yesterday we began looking into static electricity and found that it is a single, sudden transfer of electrons from on place to another. Lightning is a form of static electricity! And when we get shocks from doorknobs or the metal screws on the slide of the playground!
We did our first lab experiment. We built up an electric charge by rubbing balloons on our hair or on the carpet. The rubbing makes the balloons pick up electons from our hair or the carpet, giving it an electric charge. We then tried to see if different bits and pieces of paper would attract to the balloon.
Take a look:
What kind of charge does the balloon have after we've rubbed it against our hair?
What charge do you think the paper had that stuck to the balloon?
Why?
The reason it lifts it up is because it picks up poitev and the other dose not so they like each other.
ReplyDeletethe nagative and positive charge will let it stick together like a magnet!

when you have rubed the balloon you get a negative charge and the paper has a positive charge because when you rub the balloon the electrons on your hasir go to the balloon and then the balloon atracts the paper.

I think it was cool to rub the baloon on the hair because it was all standing up in the air.
ReplyDeleteI learnd that if you brush drie clean hair then walk over a rug your hair will be electric.The most intresting thing was that you could shok a friend!
when you have rubbed the ballon it is a negative charge so the paper had positive charges. I think it was because if you have something with a negative charge and something with also a negative charge they repell

The negative and positive charge would stuck together. It would take it up four 30 seconds.
ReplyDeleteThe baloon after we rubd it would be positive because it dosent have any more negative charge.

The balloon had a negative charge and the paper had naturaly got a nuetral charge but it became postivley charged because some electrons moved to the ballon. Therefor they attracted each other.

what kind of charge does the balloon have after we've rubbed it against our hair? answer: the balloon gets a negative charge once we've rubbed it against our hair. ju eun
ReplyDeleteWhat kind of charge does the balloon have after it was rubbed on your hair: The balloon had a negative charge.
ReplyDeleteIf you rube a ballon on your hair or on the carpet the electrons move to the ballon(from hair or carpet)that means the ballon gets a negative charge. the paper has a postitive charge that is why the ballon is atracting too the paper.

I think the balloon had a negative charge because it collectet electrons from the hair and the paper had a nuetarl charge but it became a postive charge because some electrons went from the paper to the ballon so more positive charge come which means they attract each other.

When you rube the ballon(carpet and hair)it gets a negitiv carge. So it stoch on positiv charge
ReplyDeleteJonas
the ballon has a negitive charge because the rubber collected electrons our hair has a positive charge the negitive and positive have a build up of energy called static electricty. that means that you can give you or a friend a powerful shock it picked 2 light piecess of paper and 1 hevey peice.
