Chemistry September 5 to September 9 Goals: 1. 2. 3. 4. Element Properties and the Periodic Table Atoms Atomic Substructure (Protons, Electrons, Neutrons) Models of the Atom Objectives: When finished the student will be able to: 1. 2. 3. 4. explain the arrangement of the elements in the periodic table. define an atom. describe the physical evidence that indicate that an atom has a substructure. predict the number of electrons and protons in the substructure of an atom of an element. 5. use scientific observations to develop and explain the prevailing model of an atom. Lessons: Monday: Opener: No School – Labor Day Activity: Assessment: Homework: Tuesday: Opener: What’s an atom? Activity: o Complete the construction of a class size periodic table using the periodic law. o Cutting up a piece of aluminum activity. Assessment: o Question and answer Homework: o Study for quiz over the structure of the periodic table Wednesday: Opener: Dissecting the atom.
