BASIC SCIENCE & TECHNOLOGY NOTES

OBJECTIVES: At the end of this lesson, the student should be able to:  1. Define electricity  2. Draw and label an atom  3. State what causes electricity  4. Draw an electric circuit and show different components in an electric circuit  5. State at least one function each of the components in an electric circuit.       Atom: An atom can be defined as the smallest unit of matter. It contains the neutron, proton and electron. Atoms combine to form molecules. E.g. Carbon Atom Hydrogen Atom Structure of an Atom: e.g. Carbon Atom (above) Neutron: This is the part of an atom that has no charge .It is neutral. It is found in the nucleus of the atom.  Proto n: This part of the atom carries the positive (+) charge. It is found in the nucleus. Electron: The electron is the negatively (-) charged particle of an atom.  It moves freely round the shell. Matter:...
