Recent Tutoring Session Reviews
"The student's Friday chemistry exam was postponed until Monday, so we had the chance to do further review before the test. She has really improved in her comprehension of the chemistry topics in the unit. We looked at some worksheets that had given rise to conceptual questions in definitions of compounds, elements, and mixtures. We reviewed the worksheets in question, and then we went over key topics from the study guide (like EM spectrum as well as radioactivity and half-lives). I gave her some tips on what to focus on prior to her chemistry test, including making and reviewing flashcards with EM spectrum equations, fundamental chemistry definitions (like compound, element, homogeneous and heterogeneous mixtures, etc.), and a self-drawn EM spectrum labeled with frequency, energy, and wavelength. She is prepared for her exam on Monday and I am looking forward to hearing about how she felt it went!"
"We covered ionic solutions (what will form a precipitate and what won't), molarity and molality calculations, and acid-base basics in preparation for the student's chemistry final."
"We went over some heat-energy problems and covered some of the topics from his recent test. We reviewed some difficult topics and worked to comprehend the definition of specific heat and how it is used in word problems."
"We reviewed writing out chemical equations and balancing chemical reactions. The student needed help with naming rules of chemical compounds (i.e. converting a chemical name to the appropriate chemical formula). I suggested that he review these rules for mono and polyatomic cations and anions. We then did a few limiting reagent examples where we determined the amount of excess reactant remaining and the amount of product that should be formed. I will email him some example problems of limiting reagents and writing chemical equations for his practice."
"I conducted a lesson for the student on Le Chatelier's principle. I gave a conceptual breakdown on equilibrium shifts based on concentrations of products and reactants, pressures, temperatures, and side reactions. We went over practice problems on equilibrium shifts. I gave a basic lesson on activating energy."
"We talked about the differences between covalent and ionic bonding in terms of the physical properties, drawing Lewis dot structures, how to find formal charge, resonance, exceptions to the octet rule, bond polarity, and also discussed VSEPR. One thing that the student needed help with was drawing a Lewis dot structure for a few molecules because they were exceptions. We went over a few problems and he started to get better with it. I told him some strategies on how to find formal charge quickly and also tips on how to draw the Lewis dot structure. I left him with some work for VSEPR so that we can go over it in more depth next session."
