Recent Tutoring Session Reviews
"Today we further prepared for the Unit 11 test covering Chapter 16: equilibrium. First, we clarified a concept from last session relating to how surface area affects reaction rate. As surface area increases, the reaction rate increases. In discussing the equilibrium constant, we clarified that it does not include pure solids or pure liquids. A large K value signifies that the products are favored and the reaction can near completion. A small K value means that the reactants are favored. The solubility product constant is represented by Ksp. We then walked through several practice problems from her worksheets on equilibrium. We determined how best to approach these problems in writing out the equilibrium expression first then plugging in the concentration and K values to solve for the unknown. She had some follow-up questions regarding equilibrium terminology, which I sought to clarify. Specifically, I addressed how the solubility product expression can sometimes be called the ion-product. I also addressed that the concentration of an ionic solid in contact with a saturated solution of that solid is a constant. Like last session, we reviewed useful approaches to problems such as writing out each step, always including units, and critically looking at graphs and focusing on axes to interpret them. She earned a B+ on her Unit 11 test and a B on her Unit 10 retake test."
"We did more practice tests in Earth Science. The student is very good on part 1 questions but needs more practice on the other sections."
"The student's final is this Wednesday. We reviewed problems about moles and stoichiometry as well as gas laws. She was a little rusty but should be prepared for her final."
"Today we went through some objectives which involved topics such as hemoglobin, myoglobin, fetal hemoglobin, cooperative binding, allosteric binding, sigmoidal vs hyperbolic oxygen binding curves, and the effect of CO2 and pH on oxygen binding. For the next session, we will focus on carbohydrates and lipids."
"We covered Lewis dot structures, molecular shape, bond polarity, and molecular polarity. The student had a quiz last week, and she felt like she did well on it. When I asked her if the tutoring was helping, she replied yes. We reviewed her homework, and I gave her some extra worksheets and charts. I told her to study the charts. These charts will help on her study skills, as well as prepare her for her exam."
"On Sunday, the student and I went over the uncertainty principle and the equations related to that. I was unfamiliar with some of the particular equations, so I will review those and get back to her about them. We also went over periodic trends of radius size, electronegativity, and first ionization energy. We will continue to review material as she goes over it in class."
