  • use the density formula to find the volume, mass, or density?
  • explain the meaning and consequences of a substance being more or less dense than another?
  • identify WHMIS safety symbols?
  • draw Bohr-Rutherford diagrams of the first 20 elements?

Periodic Table Activity

Before class preparation

In class activity

  • Create your own table with Mystery Elements
    • Explain the relationship between the atomic structure of an element and the position of that element in the periodic table
  • Worksheets: Periodic Table 1Periodic Table 2

After class work

Game: Bohr-Rutherford Diagrams

Before class preparation

In class activity

  • If you haven’t finished the sheet in the preparation, you will be completing the sheet in class
  • Game: Bohr-Rutherford Diagrams
    • Describe patterns in the arrangements of electrons in the first 20 elements of the periodic table, using the Bohr-Rutherford model
  • Bohr-Rutherford Card Sort
  • Bohr-Rutherford Scavenger hunt

After class work

  • Check the answers for the BR-Diagram worksheet
  • Make sure you can draw a BR-Diagram for any of the 1st 20 elements with the aid of a periodic table only, you can be quizzed at any time!

Physical and Chemical properties

Before Class Preparation
-How do we separate chemical and physical properties and how might we distinguish chemical and physical changes in substances?
-Would a change of state (e.g. solid to liquid) be a physical or chemical change?

In Class Activity
-Identifying physical and chemical changes
-Alka-Seltzer demo
-Instant snow revisit

After Class Work
-Chemical and physical change card sort

Physical Properties: Density

Before class preparation

  • How would you identify unknown objects (elements?)
  • Read over the Density Calculations worksheet, print if possible
  • Is density a physical or chemical property? Why?

In class activity

  • Density Demo & Explanation
  • Coke vs. Diet Coke
  • “Smart Meter”
  • Density Calculations (Sage & Scribe)
  • Collected next class
