Instructional Objective(s)Defines an atomSays tha particles of an atomGive reason for the stability of an atom Instructional ResourcesBackground:students aware of the moleculesknow how the particles are structured in solid,liquid and gaseous stageaMaterials:piece of a chalk, fine particles of any substanceProcedure:students are given piece of a chalk to powder itfrom that they are asked to define an atomatom is the smallest particle of a substancean atom is made up of three sub particles namely electron,proton and neutronnumber of electrons = number of protons so the atom is stablethis can be derived from the picture given to the students ExtensionsDraw a structure of an atom Assessments and RubricsDefine an atom.Name the particles of an atomGive reason for the stability of an atom External Resourceshttp://www.schoolphysics.co.uk/age14-16/Atomic%20physics/text/Atomic_str...
