Recent Tutoring Session Reviews
"We reviewed the concept of circuits together for an upcoming exam, including going through some practice problems the student had been given. The problems were primarily simple circuits with resistors in series or parallel. She seemed to do very well with most of the problems, and I think she has a pretty good understanding of the topic."
"Tonight, we worked on Chapter 15 in the student's book by doing most of the practice questions. We covered a lot about acids and bases, including different definitions (Arrhenius vs. Bronsted vs. Lewis), how to recognize a strong acid or base (mostly memorization), how to tell which acid will be strongest (number of oxygens, and atomic radius), and how pH/pKa/Ka all relate and describe acid strength. Next time, we'll work through Chapter 16 and practice titrations, acid/base equilibria, and buffers."
"Thermochemistry was the main topic for this session - we focused on problems and concepts relating to heat capacity, enthalpy, and entropy. I explained the concept of entropy in two ways - as a measure of disorder and as the tendency for energy to disperse. The student seemed to be able to do the related problems quite well."
"We went over geometric optics, reviewing briefly Snell's law, and mostly spending our time on ray diagrams. Working from there, we went over two book examples from the student's book of what we had talked about."
"Today, the student and I went over some review material for an upcoming exam. We covered rate law problems, activation energies, catalysts, and collision model. He had seen all of this material before and seemed comfortable with a lot of it even before our review. I made sure that he had the correct equations for each calculation and was familiar with the variables."
"This session was all about solutions. We covered all of the stuff for the student's upcoming quiz on the first part of the solutions material. Colloids, solutions, suspensions, dissociation and states were all among the topics covered. He still needs to work on his dissociation reactions, states and polyatomic ions in preparation for the quiz."
