2. Bonding (15 lessons)

Concepts (Non-polar) covalent bonds form between atoms of identical electronegativity.  The atoms will share electrons to complete their valence shells. Ionic bonds form between atoms of very different electronegativity.  Because one type atom is pulling electrons so much harder than the other, it actually “steals” the other atom’s electrons until each has a full valenceContinue reading “2.

1. Atoms (12 lessons)

Concepts Matter is made of atoms.  Atoms consist of a dense nucleus containing protons (p+) and neutrons (n), and the electrons (e-) that “orbit” this nucleus. According to the Bohr model of the atom, electrons exist in discrete “orbits” (energy levels) around the nucleus of an atom.  Each energy level can contain a maximum numberContinue reading “1.

Yukon First Nations people and the Klondike Gold Rush (7 periods)

*** Note to Spring 2015 students: we will not be doing all of the activities in this unit.  Check the course calendar to fin dout which assignments you must complete. In this unit, you will study the effect of the Klondike Gold Rush on Yukon First Nations cultures. The main resource we will be using isContinue reading “Yukon First Nations people and the Klondike Gold Rush (7 periods)”
