Electricity

This term we have been learning about electricity. Here is evidence of some of our learning.







Dangers Of Electricity
Written by Ezrah and Sunny

Electricity is very dangerous for example, if you put a fork or something metal in the toaster you will get a shock and if you use a hair dryer near water, you will get an electric shock.

Have you ever wondered how birds sit on the power line and not get shocked? If a bird got an electric shock, you would see smoke and feathers falling off and the bird falling to the ground.

Electricity flows through conductors such as copper wire  and some other kinds of metals but water, wood, paper, plastic, rubber, wool and string are insulators
that's why we use insulators around  power lines.

Birds are not good conductors because they are not made of copper or any kinds of metal. Electricity bypasses birds because birds are not good conductors.

Another reason birds don’t get electric shocks on power lines is because they are only touching one powerline but if they touch two powerlines that have different voltage then they would get an electric shock and they would die.

If a bird touches a powerline and another powerline with different voltage, the bird will make a pathway for the electricity to flow from the line with the most voltage to get to the power line with the least voltage and then the bird would get an electric shock and die.

Next time you see a bird on a power line you will know why the bird doesn't get an electric shock.




Why Birds Don’t Turn into Bird Pie for Mr and Mrs Twit When They Chill on the Powerline
Written By Vai and Jahzay

I’m pretty sure your wise parents have always warned you about the dangers of electricity and not playing around with it like a toy. Even playing with your devices near water can get you into trouble.

Have you ever looked up into the power lines and seen birds resisting becoming bird pie for Mr and Mrs Twit. If the birds were getting shocked they would show it by screeching, feathers would be floating down or the bird might even fall down off the power lines because it has been electrocuted.

Electricity will only shock you if you make a path for it to go to a different amount of voltage.  It will flow if the voltage is different. High voltage will only ever travel to a low voltage area. If you touch the power line then touch something else you will become part of the electricity’s path. It's bad to touch high voltage areas then touch a low voltage area at the same time because not only will it travel through you, it will kill you.

Electricity flows through good conductors like copper and will take the easiest way possible to your house. Birds will not get shocked because they are not a good conductor. Electricity will always want to take the fastest way possible so it wouldn’t want to go through the bird because it's a longer and slower way.   
So the next time you’re driving and see a bird sitting on the power line you’ll know exactly why it hasn’t turned into bird pie for Mr and Mrs Twit.
