Launch: 10/23 Grab your binder and immediately take a seat
Sit quietly and read the statement on the slip
Detectives Everyone stands up
Walk around the classroom and find another student
Read your statement out-loud to the other student
Listen as the other student reads to you
Swap slips and find a new student
Repeat!

Jigsaw Activity In this activity, the class will break into three
groups.
Your first task is to work with your group and become an expert on a type of chemical bond.
Then you will be responsible for teaching others about what you learned.
Jigsaw Activity Part I: Reading (12 min)
1. Read your assigned passage silently and individually underline important words (4 min)
2. As a group, point out important parts of the passage and discuss what they mean (2 min)
3. As a group, fill in the graphic organizer based on the information from your passage (6 min)
Jigsaw Activity Part II: Presenting (9 min)
1. First, the experts on ionic bonding will present their findings while the group members take notes (3 min)
2. Second, the expert on covalent bonding will present their findings while the group members take notes (3 min)
3. Third, the experts on metallic bonding will present their findings while the group members take notes (3 min)
Ionic bonds What happens to the electrons?
They are exchanged
What types of elements do they form between? Metals and nonmetals
What is an example? Salt = NaCl
Covalent bonds What happens to the electrons?
They are shared
What types of elements do they form between? Nonmetals and nonmetals
What is an example? Stomach acid = HCl
Metallic bonds What happens to the electrons?
They are shared, free in the “sea”
What types of elements do they form between? Metals and metals
What is an example? Copper wire = Cu
Guided Practice Are the following compounds ionic, covalent, or
metallic?
1. NaI Na = metal
I = nonmetal
2. HF H = nonmetal F = nonmetal
3. Au Au = metal
Ionic
Covalent
Metallic
