We spend much of this class practicing & reviewing lewis structures, shapes, angles, hybridization, polarity. Homework: Science fair!
We finished building the shapes with playdough (while filling out the chart on pages 7 and 8). We discussed how to determine if a molecule is polar or nonpolar.
Homework: Complete the following for the 6 molecules listed on the top of page 9 lewis strcutres with formal charge calculations shown identify the shape and bond angles determine if the molecule would be polar or nonpolar We reviewed our homework and then took a quiz on nomenclature and lewis structures. Then, we practiced doing lewis structures that have charges (pg 3 #3b). Finally, we began to notice that lewis structures allow us to determine what shape a molecule has (and its bond angles).
Homework: 1) bring 15 blank notecards 2) finish the first 4 columns on pages 7 and 8 (do the lewis structures, bonding domains, nonbonding domains, and steric number) 3) begin working on your board (due after Thanksgiving break) There is some variation due to various teachers being out this week. Be sure to listen carefully to your teacher.
Aday students: your abstract and the pink sheet is due today! We reviewed and practiced with lewis structures and began working on 3D shapes (using pg 5 & 6). Homework: Aday students: pg 2 #3 &4 pg 4 #4af quiz Monday on covalent nomenclature and lewis structures Bday students: update your abstract  due Friday get pink sheet signed We took the stats test, analyzed our science fair data, and then worked on covalent nomenclature.
Homework 1) watch 5 lewis structure videos and take DETAILED notes 2) Bday students: complete the rough draft of the abstract and have the pink form signed by your parents We reviewed homework (answers to the packet questions are found below) and then went over the answers to the stats quiz that we took last class. We took a practice quiz  you can find it below if you missed class (the answers are on page 2). Lastly, we began a new unit and learned about covalent bonding. Homework: 1) Extra stats practice worksheet (attached above if you missed class) 2) Aday students: you should be working on your rough draft of your abstract due Monday
Bday will be ahead of Aday for a week or two....We turned in our lab and took a quiz on 2sample ttests. We looked over our periodic table test and then learned about 1sample ttests.
Homework: 1) stats questions 58 2) science fair data due Thurs(Aday) and Fri(Bday) Stats Test Friday (Bday) and Monday (Aday) We learned about 2sample ttests. We took biometric data. Homework: 1) Complete the biometrics data lab (directions are on page 6 of the packet; data is below; this is a quiz grade, so come for tutoring if you need help) 2) Study for a quiz on null hypothesis and 2sample ttests next class make sure you're looking at the correct class period
We started the day by learning about graphing. We made a bar graph and a scatter plot using excel. Then, we learned about means, standard deviations, null hypothesis, and pvalues.
Homework: 1) continue working on your science fair submission  data due this week; details under science fair tab; extensions are NOT granted for students who waited until the last weekend to do their data collection and then had rain issues (lesson: don't procrastinate) 2) Write null hypothesis for questions 13 on page 4 of your packet We took the test, talked about science fair (data due next week; see the bottom of the science fair tab), and then took notes on means, standard deviations, accuracy, and precision.
Homework: work on your science fair data collection and graph (details under the science fair tab). TEST THURSDAY/FRIDAY
We looked over the atomic structure test and the periodicity quiz. We reviewed homework and then did a digital review. If you didn't finish in class, complete it for homework at socrative.com using: Teacher Room Code: MERINOE127 Use your name as your name ;) Some classes began taking notes on means and standard deviation (this is the next unit: it's not on the test) Homework: 1) complete review on socrative.com if you didn't in class 2) complete the review on the front of the periodic trends packet (some questions ask you to refer to old units like matter; the 4 families are: alkali metals, alkaline metals, halogens, and noble gases) We reviewed answers to the homework and then fixed/finished pages 46 (answers in the powerpoint below). We did some practice trend writing where we used cards to identify what vocab words were necessary to explain a trend. We finished class by taking a quiz. Homework: 1) only 2 more weekends to collect science fair data! 2) #2128 Test Thurs/Fri
We did a warm up with our video notes and then took notes on electronegativity. We did some practice with our face partner (LINK TO QUIZLET) and then practiced as a class.
Homework: 1) study explanations of trends in preparation for a quiz. 2)pg 6 #1420 We took the atomic structure test and then worked on pages 46 in the periodic table packet.
Homework 1) Be working on your science fair 2) Watch 5 periodic table videos and take DETAILED NOTES We took a few minutes to review the homework answers, and then it was time to move on to the new unit: periodic trends. We simulated Mendeleev's 'discovery' of the periodic table pattern and learned how to draw lewis dot diagrams. Homework: 1) prepare for test by completing pg 7 #1620 in the atomic structure packet 2) check your answers to the review (posted here on Wednesday). Test Thursday/Friday
We learned about ions and valence electrons. TEST THURSDAY/FRIDAY! Get tutoring if you need help.
Homework: 1) page 6 #610 2) review (it was a thin strip of paper) 3) collect science fair data (unless you haven't been given the green light to start) We turned in our lab. Then, we went over answers to the DA test and the isotope quiz. We learned about orbital diagrams using the powerpoint below. Homework: 1.) page 6 #15 2.) human/bacteria/vertebrate animal projects > work on answering the extra questions given to you by your teacher; get that updated research plan with the questions attached to your teacher by Friday/Monday.
Answer (using elimination)Today we reviewed our homework and did a challenging systems of equations atomic mass problem (see the bottom of the post). Then, we did a lab on where the atomic mass of the element 'snackium' was calculated. Some class periods began talking about electrons.
Homework: 1) Complete the video guide (found at the top of the video pages) while watching the electron videos (there are two links, try the first one first. If that doesn't work, try the back up.) 2) Complete the snackium lab by answering the following questions on your notebook paper (remember to write the #, title, and paraphrase the question before you answer it) LAB QUESTIONS 3. Interpret  Explain why the weighted average atomic mass of the element snackium is not equal to the mass of any of the pieces. 4. Peer Review  Gather the average atomic mass data from other lab groups. Explain any differences between your data and the data obtained by other groups. 5. Apply  Why are the atomic masses on the periodic table not expressed as whole numbers like the mass number of a single atom often is? 6. Research online  List the known stable isotopes for hydrogen, carbon, and mercury. Reference the websites you use. Stable refers to an isotope that is not radioactive. 7. Error Analysis  What sources of error could have led the lab groups to different final values? What modifications could you make in this investigation to reduce the incidence of error. We reviewed the homework and took a short quiz on ions and isotopes. Then, we took notes on history (see powerpoint) and learned how to calculate atomic mass. Homework: pg 5 & (unless your project hasn't been approved by your teacher: start collecting science fair data)
Today we were introduced to atoms  how they're organized, ions, and isotopes. We talked about how to name ions (quiz next class) and then learned about isotopes and isotopic notation (quiz next class). Then, we practiced with isotopic notation. Homework: 1) top 1/2 of page 3 2) student naming ions and isotopic notation in preparation for a quiz next class
We practiced DA for 30 minutes and then took the DA test. Note: it will take at least a week to grade these tests because partial credit is given. Please be patient with your teacher. When the grades are finalized, we'll go over the test in class.
Homework: begin collecting your science fair materials but don't start collecting data unless your teacher gave you permission to We spent today reviewing and practicing for the test next class.
ignore the sig fig stuff mentioned on the d key
We reviewed the homework and graded the foil lab. Then we took a DA quiz. We peer reviewed a classmate's paper. Then, we talked about the homework.
1) B3B5 (look up the equation for volume of a sphere for B3) 2) submit your background summary to TurnItIn.com by Sunday night (11:59pm)  directions under the science fair tab 3) type your research plan  information under the science fair tab
