How are battery chemicals harmful?
They are harmful because if they leak out they can dissolve your skin.
True or False: You can make electricity from farts.
True. Farts contain the gas methane, which can power generators.
What are photons?
blobs of light
True or false: The Earth is just one great big magnet.
True. The core of the Earth is surrounded by a massive sea of melted metal that sends out electric and magnetic forces.
Slap the table!
You just lost 100 points.
What would happen if you rub amber onto a bit of fur? (static electricity)
The amber would pick up some feathers. (fur but the book said feathers)
What natural force did Benjamin Franklin investigate in his most famous experiment?
Lightning.
True or false: some animals can detect electrical pulses in humans.
True. In fact, they an make them angry.
Why is it not a good idea to stand under an umbrella in a lightning storm?
Because electricity always finds the quickest route to the ground and an umbrella will create extra height.
Which way does electricity move?
Negatively charged end to positively charged end of a power source.
What did John Joseph Thomson use to bend a ray of electrons in his machine? (You can flip through the book or you can start to think logically.)
A magnet.
True or false: Electricity can travel through metal wires.
False. Electricity travels through a field around the wire.
Where are electrons located in an atom?
Most atoms are surrounded by a cloud of electrons and the electrons are circling the nucleus.
What measure of electricity is used for the word watt?
The measure of electrical power.
How come everything is not magnetic because there are atoms everywhere and atoms are magnetic?
Because atoms are very slightly magnetic and you need billions of slightly magnetic atoms together to make it feel like an actual magnet.
What machine did William Crookes build to help him understand what electricity was and what did it do? (You get 200 points for each question)
Cathode ray tube. First electric current from a battery goes in the machine, then it takes the air out of the container that might get in the way of the invisible ray. So then we know that the ray was a stream of electrons shooting out from the battery.
What measurement of electricity is used for the word Coulomb?
A measure of electrical charge.
What is a conductor?
A substance that lets electrons flow through it, such as metal.
How can electric shocks be helpful in a hospital or ambulence?
It is used when someone's heart stops beating. Doctors use a machine called a defibrillator that passes an electric current into the heart to restart it.
What is it called when eletrons are transferred from one thing to another, changing the electrical charge of each.
static electricity.
