  Day 1: Introduction of the Periodic Table Assignment
-Hand out assessment sheet to the class for the team construction of a periodic table
-Read through assessment sheet and identify for the class the s and p elements
-Students write names on sticky notes and systematically choose their own elements
-Model past project sheets that students have created
-Make students aware of how to effectively Google search for desired information
-Remainder of the class is spent in the library researching and creating materials

Day 2: Writing and Interpreting Chemical Formulas & continue PT Assignment
-The building of the Red River Cart
-The components of the Lego Man Molecule
-Students go to the library and continue periodic table assignment

Day 3: Writing and Interpreting Chemical Formulas II & Continue PT Assignment
-Worked examples: Identifying the Elemental Components of Molecular Formulas
-Assignment: Identifying Elements in Molecular Formulas
-Students go to the library and continue periodic table assignment

Day 4: Presentation of Elements and Construction of Periodic Table
-Students present on of their assigned elements
-As students present their visual aid is added to the wall revealing our periodic table

Day 5: Continue Periodic Table Presentations & Assign Atomic Theory Presentation
-Finish periodic table presentations and complete class made periodic table
-Assign Atoms and Elements: Introduction to the Atomic Theory
-Read over the assessment sheet and discuss past projects
-Students go to library to research their atomic contributor in pairs

Day 6: Contents of the Atom then Research Time for Atomic Theory Presentation
-Over Head "Contents of the Atom"
-Discuss prior knowledge, how each component contributes to chemical properties or change as we know it, and solidly link the "stability" of the proton to atomic number
-Library time to work on Atomic Theory Presentation

Day 7 Proton/Electron Calculations then Research Time for the Atomic Theory Presentation:
-Enforce the idea that protons are very stable
-Create scenarios emphasizing the outcome given an imbalance between the number of protons and electrons
-Assign "Proton/Electron/Charge Calculations"

Day 8: Mass Number & Proton/Neutron Calculation then Research Time for the Atomic Theory Presentation:
-Quiz on Proton/Electron/Charge
-Identify significant contributors to the mass of the atom
-Identify atomic number (Z), mass number (A), and their arrangement around the chemical symbol
-Enforce the idea that protons are very stable
-Assign "Proton/Neutron Calculations"
-Library time to work on Atomic Theory Presentation

Day 9: Atomic Mass and Isotope Calculations then Research Time for the Atomic Theory Presentation:
-Discuss the existence of isotopes (should be recognized by students in the prior assignment, proton/neutron calculations
-Read through Mr. Sklar's "Isotopes" information sheet
-Assign the "Isotopes" assignment
-Library time to wrap-up work on Atomic Theory Presentation

Day 10 & 11: Atomic Theory Presentations
-Quiz on Isotope Calculation
-Students present their atomic contributors in chronological order

Day 12: Recap of the Atomic Theory Contributors
-Students are given a work sheet and written material that compliment a series of overheads that highlight the development of the atomic model

Day 13: Atomic Model Quiz & Orbital Filling Electron Configuration
-Quiz on Atomic Model
-Over head on molecular orbital shapes and electron filling
-Handout: "Orbital Filling Electron Configuration"
-Read handout together then colour orbitals as they correspond to the periodic table

Day 14&15: Notes on Orbital Filling Electron Configuration
-Series of notes that go from elementary orbital electron filling to promotion of electrons from s to p orbitals, short hand notations, and utilization of noble gas cores
-The notes are accompanied by the "Electron Orbital Filling Configuration" assignment

Day 16&17: Identification of Metals: Flame Test Laboratory
-Laboratory Handout that includes the movement of electrons from the ground to the excited state, electron orbital shapes, and instructions for the laboratory that are to be read over and procedures established before students can conduct the laboratory
-Students conduct the lab
-Remaining time spent on laboratory write-up and answering assigned questions

Day 18: Identifying Trends in the Periodic Table
-Handout and read "Lewis Dot Diagrams"
-Challenge students a Lewis dot pattern in our class made periodic table
-Handout Ionization Energies and Atomic Radius student guided notes
-Students fill Ionization Energies into their periodic table and identify any notable trend
-Discuss then formulate a rational explanation to support these trends
-Students fill Atomic Radius into their periodic table and identify any notable trend
-Discuss then formulate a rational explanation to support these trends

Day 19: Practice Test
-Students are given a practice test that is designed to help them focus on the most important information covered in this unit, to identify areas of strength and areas where more effort must be concerted to achieve a desirable mark on the unit exam

Day 20: Unit Exam
 

The order of the lessons may be changed to allow weekend time for the students to work on their scientist presentation. This project is very time consuming and requires the students to coordinate and cooperatively produce a quality project.
