=Ionic and Covalent Bonds!= Now that the structure of the atom has been somewhat de-mystified, we can start building matter by combining atoms based on definte rules of engagement. Have you ever played with Lego building blocks? Each type of block can bind with a definite number of other blocks. You can form all sorts of different shapes by the way you join your blocks and the number of blocks you use. The same can be said for atoms. As you already discovered, atoms have a specific number of bonding sites or charges that can then be combined with other atoms to form a wide variety of compounds. Let's build!

__Our Focus__

 * How do atoms form ions?
 * What are the rules for ionic bonding?
 * What is the difference between an ionic compound and a covalent molecule?
 * What are the rules for covalent bonding?
 * How can you identify a subtance as either ionic or covalent just by it's characteristics?

Follow the link below to our eCurriculum for this lesson. =[|Lesson Two]= You may go through this online lesson at your own pace. This lesson is set up for you to review the basic concept information as homework so you can come to class ready for hands-on work. The protocol for each task is simple: read and interact with the information then go to the discussion tab on this wiki and post your thoughts on the discussion board. You may want to take a look at the discussion question to help you focus your learning.

__Please note the following "pace markers" to help you stay on track__

Discussion #1 (after page 1) Discussion #2: ionic bonding Ionic Compound Challenge (Goal: Complete by Day 3) //F2F Learning note: Steel Wool and water experiment: Students will experience this guided lab that involves placing steel wool into the mouth of a large test tube, inverting the test tube and standing it in a dish filled with water. They will observe the experiment and try to explain the reaction, qualitatively and quantitatively. An extension will be offered for students to seek out other simple experiments that can demonstrate a compound being made from simple reactants. Student must conduct, demonstrate and explain their reaction to the class (this may be a partner project). They must include whether or not the reactants (if applicable) and products are ionic or covalent. They also must include explanations of reactant properties in comparison to those of the product.//
 * Task one: "What" and "Why: Ionic" sections (pages 1-3)**

Discussion #3: covalent bonding rules Big 7 memory hook (Goal: complete by Day 5) //F2F Learning note: Model building: Students are to create 3-D models of given simple ionic and covalent compounds using simple materials of their choice. (Example: different sized marshmallows, red hots and colored toothpicks)//
 * Task two: "Why: covalent and carbon" (pages 4- 5)**

//F2F Learning note: Inquiry Lab: Given 8 unknown, white substances, students are to design and conduct a minimum of three tests to determine if the substances are ionic or covalent.//

Discussion link: Raft activity modifications and expectations NOTE: You must complete all three tasks to be eligible for an "A" lab grade with this unit. (Goal: task completed by Day 8)
 * Task three: Raft activity (page 6) with modifications in the the assignment description**

//F2F Learning Note: Students will be grouped critique groups. They will discuss their projects and critiques about each. They will then reflect upon the reviewing activity as an in class written assignment. This activity will be followed by a content quiz.//
