It is suggested that this unit be part of a sequential development of Science concepts beginning with the theory of the atom in relation to the three states of matter. If we follow the basic curriculum for the city, we find that by beginning with the basic building blocks of nature, the atom, we can develop a curriculum which allows us to build and expand in many directions. The atomic theory is an excellent reference point, since everything around you is made up of extremely tiny atoms the chair on which you sit, the pages of a book, etc. An atom is the smallest particle of matter that has distinct chemical and electrical characteristics. The atom is basically composed of three parts, the proton, neutron and electron.
Electricity is a form of energy.
We know what it is by what it does. It is important that the student understand that the atom is composed of electrically charged parts. The separation, frictional or chemical, of these parts creates an attraction or flow as a result of the particles re-uniting. This electron-proton flow thus creates a flow. Electrons are the smallest particles of electricity.
