 Lesson Plan for week ending 0315

Monday:

0312BW: My Planet Diary Page 374 Complete #1 and 2 on class work paper.
0312CW: Review and re-test on ions as needed. Work shop: Teacher/Student conferences
00312HW: What is the difference between ionic compounds and molecular compounds. Page 375 and 376
Tuesday:

0313BW: In general, ionic compounds form hard crystals with high melting points and conduct electric current when dissolved in water or melted. Molecular compounds usually do not conduct electric current when melted or dissolved in water and usually have low melting points and boiling points. Page 375 and 376

0313CW: Read pages 375 through 377. Write page 377 “Assess Your Understanding,” inc 1a, 1b, and “got it?”

0313HW: What do you think are some differences between acids and bases? Page 378, 379

Wednesday:

0314BW: An acid reacts with metals and carbonate, taste sour, and turns litmus paper red. A base taste bitter, feels slippery, and turns red litmus paper blue.
0314CW: Read pages 378, 379 complete Complete figure 3, 4, and “summarize” p 378, 379 on your class work paper.
0314HW: What do you think happens when you combine an acid and a base? Page 380, 381

Thursday:

0315BW: Since salts are made of ions, they share the same properties of ionic compounds, including crystal shape, high melting points and boiling points, and electric conductivity. Page 380, 381
0315CW: Read pages 380, 381 complete questions on 380 and 381. Write answers to “Assess Your Understanding” 2a, b, c, and “got it?” on your class work paper.

Review and Assessment page 383 and 384... as assigned by substitue teacher.

0315HW: Enjoy your Spring Break!

**when an atom loses an electron it becomes positively charged; when an atom gains an electron it becomes negatively charged.

**a covalent chemical bond occurs when two atoms share electrons.

**ionic bonds occur when oppositely charged ions are attracted to each other. The resulting ionic bond charge is zero.

EXTRA CREDIT: Yes, you will need to know how to combine different types of ions.

Lesson Plan for week ending 0309

Monday:
 
0305BW: Ions that are made of more than one atom are called polyatomic—poly means “many.” When a neutral atom transfers one or more electrons to another atom, it results in the formation of an ionic compound. Pages 365 to 366
0305CW: Read pages 365, 366 Complete fill-ins. Complete the figure 3 activity on class work paper. Draw the elements as models and show their electron interaction.
00305HW: What is the formula to combine Calcium, Ca, with Chloride, Cl? P 367
LAB: 201

Tuesday:
 
0306BW: To write the formula for an ionic, write the symbol of the positive ion and then the symbol for the negative ion. Add the subscripts that are needed to balance the charges.
If the negative ion is a single element the end of its name changes to –ide Negative polyatomic ion names usually end in –ate or –ite.
0306CW: Do “Apply It!” in your text book on page 368 Do “Assess Your Understanding” on class work paper. Page 368 1a, b, and c.
0306HW: What is the difference between a covalent bond and a molecular bond? P 369

Wednesday:

0307BW: Molecules occur when two or more atoms form a covalent bond and share electrons; a molecular compound is made up of molecules. In some covalent bonds one element pulls more strongly on the negative charge and creates a polar bond.
0307CW: Read pages 369, 370 complete fill-ins. Complete “communicate” from figure 6 on class work paper.
0307HW: Is it possible for a polar molecular bond to be non-polar? Explain. Page 371

Thursday:

0308BW: Not all molecules containing polar bonds are polar overall; sometimes the attractions cancel out, so the molecule is non-polar overall. P 372 The melting point and boiling point of water are much higher than the melting point and boiling point of oxygen. This is because the attraction (slight positive and negative charges) between water molecules requires more energy to overcome than the attractions between non polar oxygen molecules.  
0308CW: Complete 2a, 2b on page 371 and #3 on page 373
0308HW: Prep for Quiz
LAB: as time allows.

Friday:
