Instructional Steps Lab

Introduction (10 mins)

Collect HOMEWORK, answer questions

Students pick up properties of bonds lab to look over, read and form questions Lab (45

mins)

Students will cycle 5 stations testing properties of ionic and covalent bonds: Each station allow 5-8 minutes

 Conductivity: pure form and aqueous form  Solubility in Water  Solubility in Hexane  Melting point  Brittleness/hardness Closure (5 mins)

Lab clean up, for Lab HOMEWORK students should complete lab analysis tables to organize data for next class

Instructional Steps Elaborate

extension (30 mins)

1. Get into lab groups, students are to look at their data and determine what properties distinguishes an ionic bond from a covalent bond.

2. Each group is given one property to construct their own explanation for to share with the class

Explain (25 mins)

Group discussion on how the properties influence bond type Closure (5

1. Intro to Ionic Bonding: Predict: why are there two chlorine atoms in MgCl2? 2. Have students make observations of calcium chloride so students

a. Explain: chlorine is a poisonous gas, and calcium is a silver metal, however when combined a white solid is formed

Have student get an activity sheet, laptops, and sign in when they are finished with their prediction. Students should start with the warm up questions as they wait for their computers

(30 mins)

Working in pairs or groups of 3

 Students explore ionic bonding with the program

o When students are near activity B, stop the class and do a comprehension check and explain that the idea is that atoms bond to obtain a full octect

 in ionic bonding that happens due to a transfer of electrons.  Teacher walks around and guides students, providing enough information for them

to construct their own understanding but leading them to the correct understanding. Closure (10

mins)

1. As students finish they need to answer the questions on the last page of the packet (5 assessment questions) and turn them in for a check for understanding.

2. Students need to revisit their answer to why are their two chlorine atoms in MgCl2, and correct their answer to demonstrate what they have learned.

3. HOMEWORK: practice on ionic bonding
