Name: Wolfson Date: 11/10/14 Length of Lesson: 18 days Course: Chemistry
LESSON TOPIC: Atomic Theory
BIG IDEAS: (Content standards, assessment anchors, eligible content) objectives, and skill focus)
Atomic theory is the foundation for the study of chemistry
Chemical bonding occurs as a result of attractive forces between particles..
ESSENTIAL QUESTIONS:
In what ways has the theory of the atom changed over time due to technological improvements
What factors determine the types of chemical bonds that form between particles?
UNDERSTANDING GOALS: Students will understand:
History of Atomic Theory, Nuclear Symbols, Nuclear Chemistry, Formula Stoichiometry
Energy is absorbed or emitted when electrons move from one energy level to another within the atom.
VOCABULARY: Metric ystem, volume, mass, density, length, conversion factors, base units, derived units, scientific notation, direct/inverse proportionality, accuracy, precision, graphing, temperature.
STUDENT OBJECTIVES (COMPETENCIES/OUTCOMES):
Students will be able to
1. SWBAT trace atomic history from the Greeks through Dalton, Thomson, Rutherford and Bohr.
2. SWBAT explain the use of the cathode ray tube experiments in discovery of subatomic particles
3.SWBAT describe (and perform a “replica” of ) Rutherford’s alpha scattering experiment
4. SWBAT define, describe and use the periodic table to determine the following terms: atomic number, atomic weight, mass number, number of electrons, number of protons, and number of neutrons.
5. SWBAT summarize the laws of definite composition, multiple proportions and conservation of mass.
6. SWBAT describe and recognize the symbols and names of alpha, beta, positron and gamma radiation
7. SWBAT determine the missing part of a nuclear equation using conservation of mass
8. SWBAT complete a decay series when given radioactive changes
9. SWBAT Determine the molecular weight of a compound using the periodic table
10.SWBAT Define a mole

11. SWBAT convert between mass, mole and unit
