Recent Tutoring Session Reviews
"Today we covered solving buffer problems, titrations and Le Chatelier's principle. This was in regards to adding a strong acid, strong base, or salt to a solution, and the common ion effect as it relates to acid base equations. Today's lesson completed all the acid base chemistry that will be on the student's exam. There will be 7-8 more sessions before his exam. In those sessions, we will cover thermodynamics, kinetics, solutions, molecular geometry, more electro-chemistry, and gases."
"We were not able to finish the practice test during our last session so we continued today. The student had 12 net ionic reactions to write from given reactions. She was able to successfully predict the products and write the net ionic equations. She was not outright stumped by any of the questions. She was able to reason her way through most of the questions. All of the SAT question were some variation of true/false questions."
"Reviewed concepts while working through part of a multiple choice practice test. From there, had the student work through a long form question, allowing him to ask questions when he got stuck. After that, recommended he take the rest of the questions in the section and see how he does and use that, plus a recent practice test he took in class to help him make a final decision on whether to take the exam."
"The student and I discussed organic chemistry and completed kinetics problems using mechanisms in our session. He has not learned organic chemistry in class, so we will need to review the prep guide chapter in more depth before his AP exam. No concerns from this session."
"The student and I completed more multiple choice and free response practice questions for the AP exam and reviewed topics such as periodic trends (electronegativity/atomic radius), equation writing and balancing, oxidation/reduction reactions, and Gibbs free energy. I think he has made a lot of progress the last few weeks and is on good track for the test next week."
"I brought worksheets over on thermochemistry/thermodynamics. The student practiced multiple choice, short response, and long response questions for this subject matter. He is strong at figuring out what equations he needs to use to solve the problem correctly, but still needs to focus on ensuring he is putting the right values into the equation. I left him homework of doing another diagnostic exam, and we will review it on Wednesday."
"Today's session was dedicated to finishing up electrochemistry. This involved using equations that allow you to compare Gibbs free energy, the equilibrium constant, and the standard cell potential. He showed great promise in knowing which equations to use for specific equations. We concluded the session by reviewing measurement strategies in the laboratory and why they are used. He is now in the stage where he needs to take some practice tests before we can determine what else he needs to review. He will take a practice test this week, and we can review the test next Wednesday to see what he can improve. My goal at this point in time is to solidify his understanding of all material, as well as make sure that he is time effective on the actual AP test."
"We covered organic chemistry starting with hydrocarbons and then observing and discussing polymers of simple chains, branched and then ketones, aldehydes, ethers, alcohols, amines, sugars and then worked into biochemistry. We focused on pentose sugars, amino acids and how phosphorus is key in creating the DNA and RNA framework composed of ribose sugars links with P with the 4 key amino acids sandwiched in between. We finished with a discussion of enzymes and how transition metals such as Ni, Fe, Mg and Mn act as catalysts in key enzymes."
"The student and I reviewed some practice sessions for her final in AP Chemistry. Her final is largely based on the exam. I left her with some tips on last minute studying and on how to approach the exam."
"We worked on practice problems for her upcoming chemistry exam. The student seems to be doing really well with acid/base chemistry. However, she will need to review more of the introductory material such as chemical properties and Henry's Law, PV=nRT. She's going to finish up the work sheet and this coming Saturday we'll go through the material again. I'd like to provide some extra practice work from my chemistry text if she has the time. I think in general, for her to do well on her test, she just needs to practice. I was very proud of her ability to read the question and interpret what it's asking. For standardized tests this is a great skill set and will help with tests."
"The student had expressed difficulty in Kinetics so this class was purely devoted to that. I prepared a short lesson where we walked through all the various aspects of kinetics. The topic which he struggled with conceptually was determining the rate laws using experimental data. It took a little bit for him to grasp the idea of holding two different experimental concentrations for one substance as a constant while varying the other. Once we covered the lesson, we went over practice problems."
"Today we continued to work through acid base neutralization reactions and further worked through disassociation FRQ that the student's teacher had given her. We continued using this as practice for the AP exam coming up in early May."
