Electricity!
2
Atoms and Electricity You use electricity every day, but do you know what it is? To understand electricity you have to understand atoms. Atoms contain charged particles. A proton is a positively charged particle. An electron is a negatively charged partle.
3
Atoms: are the smallest component of an element having all of the chemical properties of that element.
4
An atom can have more electrons than protons. This gives the atom a negative charge. An atom with more protons than electrons has a positive charge. Atoms with opposite charges attract each other.
5
In an atom, electrons move around the outside of the nucleus. In some elements, electrons can also move from one atom to another. Protons don’t move this way… ELECTRON MOVEMENT PRODUCES ELECTRICITY!
7
REMEBER THIS! E LECTRON MOVEMENT PRODUCES ELECTRICITY!!! E lectricity, or electric energy: is a form of energy produced by moving electrons.
8
Electricity (or electric energy) can be changed to other forms of energy. People use electricity to run lights in homes, schools, and offices. Electricity can also run street lights and traffic lights. Lamps change energy into light energy!
9
Look at the fountain below… The lights use electricity. The fountain also uses electrity in another way.
10
Electric motors pump the water through the fountain and pushes it up into the air. Here, electricity changes to motion, or mechanical energy. Mechanical (or motion) energy:is the energy of motion that is put to work. It can also be the energy of moving parts of a certain machine, like an engine.
11
Electric motors can be small enough to power a model train. They can be large enough to drive a huge frieght train or a ship loaded with cargo. Electric motors can even run some cars.
12
Electricity can also change to heat energy. Toasters and electric ovens produce heat from electricity. So do hair dryers. Many homes are heated by electricity.
13
REMEBER THIS! Don’t forget that ELECTRO MOVEMENT PRODUCES ELECTRICITY!!! Electricity, or electric energy: is a form of energy produced by moving electrons.

The end!
