Date: 10/21/14 and 10/22/14

Class: Physical Science

Periods: W1,2,4 and B2

Outcomes: Students will be able to describe why atoms form chemical bonds.

Standards: 9-12.P.1.2

Student Needs: 

Assessment Plan: Ticket to leave: Students will predict how many electrons Oxygen needs to gain to become stable.

Lesson Outline: Hand in papers. Ask students what stood out to them about the element families. Ask students how many neutrons are in an atom of K-42 > Ask students what they know about chemical bonds, compounds and molecules > Ask students why atoms form bonds > Notes over Chapter 20 Section 1 > Practice figuring out how atoms reach stability > Ask students to predict how many electrons Oxygen needs to gain to become stable > HW: Read 20.2 What is the difference between ionic and covalent bonds?
