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 p-values.
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 1-3 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 4-6 (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) #21-28 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 #14-20 We took the atomic structure test and then worked on pages 4-6 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 #16-20 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 #6-10 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 #1-5 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.
