If you rub a balloon ob your hair,then move the balloon away slightly you will find that your hair stands on end-it is attracted to the balloon.This is caused by electric charges building up on the balloon.These electric charges come from your hair so your hair now has less of them.The balloon has an overall negative charge while your hair has an overall positive charge.Opposite charges attract one another and so,your hair is attracted to the balloon.It stands on end! These electrical charges don't move anywhere because neither your hair or the balloon conduct electricity very well.

Batteries use chemicals to store energy.

Human bodies contain 70 percent water, and water conducts electricity.

A battery is made out of a metal cap, a carbon rod, a Magness Exide and a zinc case

# data[].attributes.body
Things like mobile phones, torches and MP3 players are all powered by batteries.

Inside cells are liquids that can burn you if you touch it.

# data[].attributes.body
Water is a conducter and most of our body is made up off water or liquid so electricity can flow through your body.

# data[].attributes.body
Conducters are materials that electric currents (electricity) can move through easily like some metals but insulators stop electric currents from passing through them for example rubber.

# data[].attributes.body
Rubber,glass and plastic are good insulators

Electricity will travel through any conductors it can to get to the ground ,making any short-cuts.

# data[].attributes.body
Electricity could be serious because if you get water on you'r device.

The chemical reactions in batteries don't last forever - that's why batteries run out of charge.

# data[].attributes.body
Mains electricity can be deadly with 230 volts of electricity to put that in to perspective a batterie has 1.5 too 9 volts of electricity.

Water is a conductor your body is mostly made out of water...so electricity can flow through you .You can die or really hurt

# data[].attributes.body
Coppers are good conductors because they carry electricity in wires and electricited flexes .

If you rub a balloon on your hair it your hair spikes up because electric charges flow because of the balloon.

# data[].attributes.body
Balloons has negative charges when you rub it on your hair, so your hair would be attracted to the balloon!

Mains electricity is great for all sorts of important things that require lots of energy.

# data[].attributes.body
You can be serioursly hurt or killed if you mess about with electrical appliences.

# data[].attributes.body
Btteries are great for powering electrical appliances that needs less energy and that need to be portable we need to be able to carry them around.

# data[].attributes.body
In our home we get some of our electricity from batteries and from mains. Batteries are good for powering electrical appliances.

# data[].attributes.body
Household wires are covered in plastic so you cant touch the metal core witch carries electricity witch can shock you if you cut a wire .

# data[].attributes.body
Chemicals in batteries conduct electrons to power our electronics

Electricity always tries to go to the ground,this is why lightning happens and the reason tall objects get hit by it because they are a conductor.
