In this lesson students delve into covalent bonding through taking notes and practicing with whiteboards and individual practice. Students have already learned the basics of covalent bonds through the introductory lessons of and. Within this lesson the only resource needed is whiteboards, dry-erase markers, and erasers for the covalent naming whiteboard practice. In this section of the lesson I engage students in the topic in two ways. I have students do an Ionic Compound Quick Review to help reinforce what we have already learned about ionic compounds. I allow them to use their notes and to work with their table partner if need be. I have students perform Periodic Table Aerobics. See my in the previous lesson on Ionic Compounds. In this section of the lesson I discuss metallic bonding slide 2 , covalent bonding slides 3-5 , how electronegativity differences dictate bond type slides 6-12 , and how to name covalent bonds slides 13-17. This is tricky and I have them try to solve the problems through both using the electronegativity values and by looking at the location of the elements on the periodic table I just remind them that Hydrogen has the same electronegativity value as Phosphorous. Students find covalent name MUCH easier than ionic, the only issue is remembering the proper prefixes. For this section of the lesson students have an opportunity to practice covalent naming. To help them I have them keep their notes out with the table of prefixes. Also, I have a poster in the classroom of the prefixes for covalent compounds for students to refer to. The first thing students do to practice naming covalent compounds is doing Partner Whiteboards. I have students work with partners to encourage them to discuss why they think that a certain answer is correct. I periodically remind them to switch partners in terms of who is doing the writing throughout the whiteboard session. I put up a problem on the PowerPoint and then have students hold up their answers. I either give thumbs up or down and if they get it incorrect they should retry. After most students answer I go onto the next answer. If it is one that many get wrong I go over why the correct answer is correct either by myself explaining or having a student explain how they determined the answer. See my embedded Covalent Whiteboard Reflection to get a better idea of how this works in my class. The most common mistake is students using the wrong prefix, not properly changing the ending of the second element, or not putting the of atoms in the correct location. These are pictures , , of some of the common mistakes. The second thing that students do is individual practice with covalent naming. For homework students perform the practice questions at the bottom of the last page of their. I stamp the homework for completion when students come to class the next day. I then go over the answers to the homework using the. Most students that have problems with the homework get confused with naming remembering which rules are for Ionic and which rules are for Covalent. Also many forget to write down whether the covalent compounds are polar or non-polar. This shows a copy of the filled in homework by a student on the third page.
