Students began and completed the Chemical Reactions Vocabulary (48 pts) in class today.

Students went over the Chemical Bonding Ch. Review, were urged to review their polyatomic ions, due to the bad grades on the prior test, and then took the Chemical Bonds Test (100 pts). They began the Chemical Reactions Voc. (48 pts) after the test.

Students took the Chemical Bonding Vocabulary Test (26 pts), worked on a worksheet that shows that they know how to read the Periodic Table and Elements properties, Element Code (38 pts) and had the polyatomic ion test (24 pts). They will have the Chemical Bonding Chapter Test on tomorrow.

Students had a "Element Symbols" Test and completed the Chemical Bonding Chapter Review (68pts) in class. They will have a Polyatomic Ion Test (26 pts) on tomorrow as well as a Chemical Bonding Voc. Test. The Chapter test on Chemical Bonding will be Friday.

Students began learning about covalent bonding. We discussed molecules, covalent bonding, polar & nonpolar molecules and covalent nomenclature. They observed a podcast on Covalent Nomenclature and had 2 WS's (Naming Covalent Compounds - 50 pts) & (Writing Covalent Formulas - 50 pts). They will have a test on naming and identifying polyatomic ions tomorrow and a vocabulary test on Chemical Bonding on Thursday. The Chemical Bonding Chapter Test will be on Friday.

Students began class by looking at a PopaPodcast on writing Ionic Formulas with Polyatomic Ions. Upon conclusion of the podcast, we worked 4 problems involving polyatomic ions on the board as a class. Then, we began work on the "Writing Ionic Formulas with Polyatomic Ions".(50 pts). We will be working on the Chemical Naming and writing formulas for ionic & covalent compounds this week.

Students took notes from the PowerPoint on Polyatomic Ions. They learned the names of given polyatomic ions, how to recognize them and how to name ionic compounds with Polyatomic Ions. We concluded class answering the compounds on a worksheet, "Naming Compounds Containing Polyatomic Ions" (50 pts). They were instructed to begin learning the names, symbols and charges of the polyatomic ions for a test next week. They will take the ACT Aspire Test on tomorrow.

Students learned how to write chemical formulas for transition metals using Roman numerals. We also went in reverse and learned how to take chemical formulas for transition elements and name chemical formulas w/transition elements. They had two worksheets to complete, Naming Ionic Compounds with Polyvalent Ions (50 pts) and Writing Chemical Formulas w/Polyvalent Ions (50 pts). One worksheet is due during GPS and the other tomorrow. Tenth grade students will be taking the ACT Aspire Science Test via laptop in class on Friday.

Students reviewed the terms oxidation number and then watched a podcast by PoppaPodcast on "Writing Chemical Formulas for Binary Ionic Compounds". Then, we worked a few practice problems for writing binary ionic formulas. We concluded class by completing the "Writing Ionic Formulas" (50 pts) worksheet. Those that did not finish were allowed to complete the worksheet at home.
