Recent Tutoring Session Reviews
"Today we covered electrochemistry, SI units, significant figures in calculations, solubility equilibria, and redox reactions. We also did 7 questions from the AP chemistry exam. We will be doing these questions every session in preparation of his exam the first week of May. I also gave him a quiz in the beginning of class to evaluate whether or not the material from the last session was retained. He did well, only missing 2 of the 20 questions."
"The student and I reviewed acid-base reactions and buffers in our session. We used her worksheet, 4.1.7, to review concepts including: determining the stronger acid/base using bond length and electronegativity, calculating the pH of an acid solution, and showing the difference in dissociation of weak acids versus strong acids using the particle model. I also gave her an introduction to buffers, e.g. how to make them, what the they do, and important concepts pertaining to them. We will continue to review buffers in our next session as well as begin to review questions specific to the AP Exam."
"Today the student wanted to go over redox reactions and redox reaction problems. We began by discussing the differences between electrolytic and voltaic cells. After that, we went over her old redox exam, which included simple problems on her exam over the topics of oxidation numbers, oxidizing and reducing agents, use of reduction potentials, and spontaneity of reactions. We went over oxidation states and related them to the concept of electronegativity. She is now comfortable with calculating oxidation states and using them to solve redox problems."
"In Today's session we covered topics encompassed by thermodynamics, such as spontaneity, entropy, and free energy. We spent most of the time going over practice problems in her text book, and I would explain concepts related to the equations needed to solve them. At the end of the session I asked her to continue on the challenge problems to get extra practice, since she has an upcoming exam on the topic on Tuesday. I feel she is a quick learner and very focused."
"We started the session going over her calculus homework. We then began to review chemistry material. I suggested that she find a review book to prepare for her final and AP test."
"We covered a lesson on chemical formulas (balancing, nomenclature, types of reactions and predicting products of reactions). I left him with homework of reviewing his polyatomic ions (quiz first thing next session) and doing the problems in Section 5 of his AP Chemistry practice booklet on chemical equations."
"For this session we covered the end of acids and bases. The student still had a great understanding of the math and concepts involved, and only had one question out of the many problems assigned. We had a general review of solubility constants and how this part of the chapter may apply to the formation of an effective buffer solution."
"The student wanted to cover questions she had from her AP Chemistry review book on gases. I went into deeper detail than the book as we answered each one, though it mostly boiled down to an understanding of PV=nRT."
"We talked about and worked through missed problems from a recent quiz in Calculus (mostly Taylor/Maclaurin series problems). Then we moved to AP Chemistry, where we worked through a series of sample AP problems in a variety of topics. These included precipitates, titration, understanding lab error, etc."
"The student and I worked on her Thermodynamics homework, which is due on 4/8. Once we found the appropriate equations, the student was very good at solving for the correct answer, which makes her feel confident for her upcoming exam. She knows that if she can memorize the equations, then she will be able to solve the problems. As we worked through the problems together, I made an equation sheet for her. The student will be on spring break for the next 2 weeks. When she returns, the class will have a week or so to prepare for the AP exam."
"The student's school is on spring break, so today served as a unique chance to focus on the AP test without having to worry about her schoolwork. Today we reviewed stoichiometry (molarity, limiting reagent, and some titrations). This was very easy for her, but it was certainly still beneficial to go over the (many) practice problems. Even the free response problems didn't seem too hard for her! In total, I'm very excited for her. We plan to meet on Friday for some more AP review, but I think with her natural sense of reasoning and her class's constant reviewing, she will do very well."
"With the chemistry test fast approaching, I decided to provide the student with some organic chemistry background knowledge for this week's sessions. We discussed alkanes, alkenes, and alkynes as well as the hybridization of the carbons involved in the bonds. We also began to go over the general functional groups that may show up on the test. Finally, we talked about types of isomers, and how to distinguish between them."
