=Electrons and Bonding!= So you know about atoms. Those tiny buggers are everywhere and in everything! As if that wasn't mind-blowing...they are made of even smaller particles. It's these unbelievably small things that control the behavior of the atoms. I mean really, how can there be under 100 naturally occurring elements in the world and infinite kinds of matter? Join me on a quest to understand how atoms join! __**Our focus:**__ What are valance electrons and how can I count them? How are valence electrons key to atom bonding? Since atoms are so small, how can I model atomic structure to demonstrate bonding concepts? How are valence electrons, atom bonding behavior and the periodic table related?

Follow the link below to our eCurriculum for this lesson. =[|Lesson one]= 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__

2 discussion topics; (Goal: Complete by Day 2)
 * Task one: "What" and "Why" sections (pages 1-2)**

//F2F Learning note: students will complete hands-on activities 1-2 from the following site in class as well as have class discussions about valence electrons during days 1-3. []//

1 assignment and 1discussion topic (Goal: complete by Day 4)
 * Task two: "Lewis structures" and "Octet Rule" (pages 3-4)**

//F2F Learning note: The Lewis structure assignment has aF2F component. Please just look over idea. You can comment by posting if you wish, but are not expected to complete it. Also students will complete hands-on activities 3-5 from the Galileo site; build models and discuss Lewis Dot structures during days 3-6. During this time students may be working in different paces in class.//

Link, email or hand in your lab with critiques to Mrs. Bates for credit. NOTE: You must complete the extension to be eligible for an "A" lab grade with this unit. (Goal: task completed by Day 6)
 * Task three: Extension - see discussion tab**

//F2F Learning Note: Checking for understanding (formative assessment):// //Students will be grouped by pace levels (if possible in partnerships or groups of three). Give each group the task of creating a periodic table that visually shows groups, # valence electrons, Lewis dot structure, reactivity trends up/down/side to side; electron behavior (gaining or losing for stability), charge of ion (if it forms one). They are challenged to create an interesting and informative periodic table using what ever materials or technology they would like. The only restrictions: their project must be authentic, the information must be accurate, they must have a key, they must show relationships through grouping created by current periodic table arrangement, and must include element names (only using main group elements!) They will be graded on completion of criteria and creativity (through peer and teacher evaluation rubrics).//
