ESSENTIAL QUESTION: How do molecules interact to form covalent bonds?

NGSSS: SC.912.P.8.6; SC.912.P.8.7

BENCHMARK(S):

-Distinguish between bonding forces holding compounds together and other attractive forces, including hydrogen bonding and van der Waals forces.  

-Interpret formula representations of molecules and compounds in terms of composition and structure.

LEARNING OBJECTIVES:  Students will be able to:

-distinguish between bonding forces holding compounds together and other attractive forces, including hydrogen bonding and an der Waals forces.

BELL RINGER:  Answer the questions on the handout. You will then enter your answers using the clicker CPS System. I apologize for not including the questions here. My computer is on the fritz and I cannot scan documents on this computer. Once my computer is fixed, I will go back and add any missing pages.

VOCABULARY: valence electron  electron dot structure, octet rule, halide ion, ionic bond, ionic compound, chemical formula, formula unit, coordination number, metallic bond, alloy

HOME LEARNING: study for the  mid-year exam.

INFORMATION PRESENTED IN CLASS:

Students reviewed information with the clickers and participated in the discussion. Students then reviewed covalent boding by viewing the Bitesize revision presentation from the UK. Click on the link Covalent Bonding to learn more.

We then took notes on molecular compound formation (formation of compounds with covalent bonds). We will pick up note taking at the next class session.

ESSENTIAL QUESTION: How do molecules interact to form covalent bonds?

NGSSS: SC.912.P.8.6; SC.912.P.8.7

BENCHMARK(S):

-Distinguish between bonding forces holding compounds together and other attractive forces, including hydrogen bonding and van der Waals forces.  

-Interpret formula representations of molecules and compounds in terms of composition and structure.

LEARNING OBJECTIVES:  Students will be able to:

-distinguish between bonding forces holding compounds together and other attractive forces, including hydrogen bonding and an der Waals forces.

BELL RINGER:  Write the name of each of the first 4 compounds. We will complete the page after the videos.

For the bell ringer:
Look at the formula and use the conventions you've been taught to name the compound. Remember, mono=one; di=two; tri=three; tetra=four; penta=five; hexa=six. Also remember that the first element in a compound never has mono added to it, but will have di, trip, etc. as necessary. Any of the elements in groups 5a, 6a, and 7a have their names changed once they acquire another electron, with the ending -ide being added to the element's name.

VOCABULARY: valence electron  electron dot structure, octet rule, halide ion, ionic bond, ionic compound, chemical formula, formula unit, coordination number, metallic bond, alloy

HOME LEARNING: study for the  mid-year exam.

INFORMATION PRESENTED IN CLASS:

Students completed the remainder of the handout, listing ratio of metal to non-metal elements, the type of bond (single, double, triple), and pasting the compound in the space provided. 

Students then made four new compounds and completed the worksheet. Find the worksheets for this section below.

Now make up four compounds from the remainder of the cations/anions. Be sure to record the formula, ration of metal to non-metal, the name of compound and type of bond. Paste the cutouts in the appropriate place.

These are the cutouts. I suggest coloring all the cations one color and the anions another color. Don't color so darkly that you can't read what's on the slip.

ESSENTIAL QUESTION: How do molecules interact to form covalent bonds?

NGSSS: SC.912.P.8.6; SC.912.P.8.7

BENCHMARK(S):

-Distinguish between bonding forces holding compounds together and other attractive forces, including hydrogen bonding and van der Waals forces.  

-Interpret formula representations of molecules and compounds in terms of composition and structure.

LEARNING OBJECTIVES:  Students will be able to:

-distinguish between bonding forces holding compounds together and other attractive forces, including hydrogen bonding and an der Waals forces.

BELL RINGER: Read the cartoon and suggest elements for each character. Use your periodic table.

VOCABULARY: valence electron  electron dot structure, octet rule, halide ion, ionic bond, ionic compound, chemical formula, formula unit, coordination number, metallic bond, alloy

HOME LEARNING: HL 7/work on your science fair paper/project

INFORMATION PRESENTED IN CLASS:

Students completed the bell ringer and added it to their interactive notebook. Be sure you have placed the date, benchmark, essential question and page number in your table of contents. Then, set up a Cornell notes page with date, page number and essential question. Place the cartoon in the center of the Cornell notes page.

We then reviewed HL 8. 

Students then watched the BrainPop movie Chemical Bonds. You can access the movie with the user name: palm beach and password: palm beach.

We then completed a virtual covalent bonding activity, found at Covalent Bonding.

Students then began notes on covalent bonding. The entire powerpoint will be found on My Big Campus. Since we did not complete the entire chapter, I will post the completed power point on My Big Campus and the shortened movie version here when we do complete all four sections. 

Make sure all work is submitted by Wednesday.

ESSENTIAL QUESTION: Why do bonds form between elements?

NGSSS: SC.912.P.8.6

BENCHMARK(S):

-Distinguish between bonding forces holding compounds together and other attractive forces, including hydrogen bonding and van der Waals forces.  

LEARNING OBJECTIVES:  Students will be able to:

-distinguish between ionic, covalent bonds, and metallic bonds and explain how they are formed.

BELL RINGER: Complete the five questions from the top of the handout with AT, NT or ST.

VOCABULARY: valence electron  electron dot structure, octet rule, halide ion, ionic bond, ionic compound, chemical formula, formula unit, coordination number, metallic bond, alloy

HOME LEARNING: HL 7/work on your science fair paper/project

INFORMATION PRESENTED IN CLASS:
Students completed questions 1-5 on the handout below, discussing why they chose the answers they did.

Bell ringer - complete questions 1-5 on THIS sheet. Place in your notebook.
HL 8. On your OWN paper, answer questions 6-13, placing ONLY the answers that would correctly complete each statement on your paper

Students reviewed home learning 7 and received instructions for HL 8, which can be found above.

We also completed note on ionic and metallic bonding. Remember, if you missed some of the notes, you can find the entire power point on My Big Campus. You can also find the shortened movie version of the notes on this site (see last class blog notes).

We then practiced recognizing bond types. The handout can be found below. Complete and place in your notebook.

Read the directions to write either ionic, covalent, or both for the bond types. You will also need a periodic table! Place the completed handout in your interactive notebook.

Students continued to practice making ionic bonds on their personal devices. Click the link Ionic Bonding to practice this skill.

Students also completed an exit slip on bonding.

Don't forget, projects are due in class on Monday!

HOME LEARNING: HL 7/work on your science fair paper/project

INFORMATION PRESENTED IN CLASS:
Students received HL 7, which is to be done on your own paper. Be sure to write your answers on the handout and place in your interactive notebook.

This is HL 7. Be sure to answer all questions accordingly.

Students took notes on ionic and metallic bonding. The powerpoint, in movie form, is found below. You can find the actual and inclusive powerpoint on My Big Campus with today's date. Below, you will find a shortened version of that information. You need only take notes on the information printed in red.

This is the shortened version of the powerpoint, minus much of the explanatory information and examples. To see the entire powerpoint, please go to My Big Campus.

We will conclude notes next class.

Don't forget, papers and projects are due next Monday!

Home learning is due next class!
