We reviewed the prefixes and how to write covalent formulas. Then, students were given the "Writing Chemical Formulas for Covalent Compounds" WS (50 pts). They were then told to complete the "Writing Chemical Formulas for Ionic Compounds" WS (50 pts) also to compare the ways to write the formulas. Students were then reminded of the Vocabulary Test (24 pts) on Thursday and the Symbols/Polyatomic Ions Test (50 pts) on Wednesday. The "Chemical Bonding" Chapter Test will be on Friday.
Earthquakes & Earth’s Interior
Today, we completed the notes on Earthquakes, long & short term predictions and began talking about the layers of the earth. We mentioned the Earth's layers by composition and physical traits and then discussed how we know the layers makeup. Also, they were reminded to have their colored pencils for class tomorrow for the assignment.
Covalent Compounds
We copied the final notes from the PowerPoint on Chemical Bonds dealing w/covalent bonding. After the notes, we listened to PAPAPODCAST and viewed the podcast on Naming Covalent Compounds. We completed class with a worksheet on "Naming Covalent Compounds". It was due at the end of 7th period today (Study Hall). Students were reminded to be aware of the Test coming on the Names of the Polyatomic Ions and Element Symbols.
Earthquakes
Students took notes from the "Earthquakes and Earth's Interior" PowerPoint. We discussed the use of Seismic Station and differences in P and S waves to located earthquakes. Class was concluded with the notes on location of the Ring of Fire.
Polyatomic Ions
Today, we went over the names, charges and symbols for the polyatomic ions. We explained the difference in naming compounds w/and without polyatomic ions. Class was concluded by students getting a worksheet on "Naming Ionic Compounds w/Polyatomic Ions" (50 pts).
6th
We went over the difference in naming Ionic compounds w/Transition Elements. We practiced several problems on the board and concluded class with the "Naming Compounds with Polyvalent Elements" (50 pts). They were also given the "Chemical Bonds" Vocabulary (30 pts) to complete for homework.
Earthquakes & Earth’s Interior
We continued the notes on "Earthquakes & Earth's Interior" from the PowerPoint. We discussed the difference in aftershock/foreshock, elastic energy theory, and seismology. Students were reminded to have their colored pencils daily.
Naming Ionic Formulas w/Transition Elements
Today, we reviewed the topics we've covered so far w/chemical formulas. We've
1 - Named Ionic Compounds
2 - Written Chemical Formulas for Ionic Compounds
3 - Written Chemical Formulas for Ionic Compounds w/Transition Elements.
We then introduced the next step in Chemical Formulas...Naming Ionic Formulas w/Transition Elements. We worked several practice problems on the board then assigned the worksheet, "Naming Chemical Formulas for Ionic Compounds with Polyvalent Ions".
Earthquakes
We began the notes on "Earthquakes and Earth's Interior" today. Students were advised to bring their colored pencils everyday.
Ionic Formulas w/Transition Elements
We looked at a podcast showing how to write formulas w/the transition elements. Then, we completed the Ionic Formulas w/Polyvalent Elements worksheet (50 pts)
Earthquakes
We had a quick poptest/preview test to see what they knew about earthquakes. Some thought they knew a lot, but knew very little about earthquakes. Afterwards, they worked on the "Earthquakes and Earth's Interior" Review Questions (60 pts). Several students did not take advantage of the time they were given in class. The worksheet is due on tomorrow.
