Part 1 – Attraction and Repulsion
This presentation shows how contact between different materials can result in attraction or repulsion. Experimental results are discussed that led to Ben Franklin’s one fluid theory of electricity.
It explains how clues were found from rubbing different materials together.
Part 2 – Electricity as a Fluid
This presentation illustrates the one fluid theory of charge first described by Benjamin Franklin. Also explains conventional versus electron current flow.
Part 3 – Atoms and Electricity
This presentation illustrates the parts of an atom. It shows how the atom is made of electric charges in the form of protons and electrons.
Other related topics include atoms. atomic structure, Coulombs Law of Charges, the force between charges, the unit charge (coulomb), forces between sub-atomic particles, ionization, ions, ionic bonding, the strong nuclear force, the nucleaus, protons, and neutrons.
Part 4 – Atoms and Elements
This presentation shows how the elements are the building blocks of all matter. It describes the atoms, bonds between atoms, molecules, atomic number, atomic mass (weight), isotopes, atomic excitation and ionization.
Part 5 – Conductor and Insulators
This presentation describes the properties that make some elements and materials conductors or electricity, while other materials are insulators. Topic include electron orbitals and shells, free electrons, valence electrons.
Introduces the analogy of a wire as being like a pipe carrying water. Describes conductivity and resistance.
