Recent Tutoring Session Reviews
"In this session, we reviewed aspects related to molecular biology. This mainly pertained to the makeup of the molecules of life, such as nucleic acids, proteins, carbohydrates, and lipids and their characteristics, and it included how they are formed. We also discussed the components of the lipid bilayer, aspects of diffusion, and other things pertaining to molecular biology. She had a very good understanding of the material and used this session as a review in preparation for the AP exam."
"The student worked on her assignment from class which covered neurons, action potentials, neurotransmitters, etc. We spent some time reviewing and talking about how signals propagate through nerves and the brain."
"Today we went over the student's homework on angular motion for his upcoming test. The student says he feels more confident about his test. I think more sessions were required to fully cover the subject, but we simply didn't have enough time."
"We briefly looked over the student's last test. He made an 88, which was higher than the class average. During this session we focused on the basics of covalent and ionic bonding, Zeffective, and electronegativity. We also did some oxidation state problems. Then we reviewed how to name binary ionic compounds and binary compounds between two nonmetals. We discussed the importance of memorizing polyatomic ions, and we also looked at nomenclature related to acids."
"The student has an upcoming physics test right before spring break, so we prepared her for that. We started by her finishing her homework on series and parallel circuits (combination circuits) and I took a good amount of time breaking down what was happening with the current and voltage in each resistor. Doing 4 problems took a large chunk of time so we ended the lesson with a few extra problems that I had pulled up. The extra problems were similar to her homework but had different wording (good for diversity) and asked to solve for different magnitudes. I think she will be well prepared for her test, she just has to really slow down and think about each component of the circuit and double check her answers to see if they make sense."
"The student worked on a homework assignment dealing with vapor pressure, sublimation/evaporation, the Clausius-Clapeyron equation, and boiling points. Then went over some of the questions on the review packet for the upcoming test. The student did great today!"
"During this session we focused on equilibrium. We looked at how to find the equilibrium constant and how equilibrium constants of similar equations are related to each other. We discussed how to find the equilibrium constant of an equation when we know the equilibrium constants of two or more reaction that when combined produce the reaction of the original equilibrium constant. We also covered Le Chatelier's principle. With Le Chatelier's principle we primarily discussed how changes in volume and pressure affect the direction of the reaction."
"We went over angular velocity and acceleration as well as center of gravity. The student has a test next week. We did several of the homework problems calculating center of gravity and used the kinematic equations for velocity and acceleration. We also used the force equation for heavenly body equations. Once she gets the problem set up, it is usually smooth sailing."
"The student totally nailed the problems about concentration and Molarity. The material from the Review Sheet that we covered went well. The student had a good grasp on solubility especially, and are starting to get the big picture of chemical properties of substances. We'll meet again before the student's test to review the final sections and review some of the older material that may show up on the test."
"The student was concentrating on problems of voltage and capacitance. The trickiest part is getting a handle on what voltage means regarding work and change in potential energy, especially with regard to signs. That is a challenging conceptual topic, and she seemed to be able to solve problems very effectively once we had set them up, even through several layers of calculation."
"We went over Gibbs free energy, entropy, and enthalpy. We went over a worksheet that had problems regarding these concepts. We also went over some topics on kinetics, microstates, and laws of thermodynamics. The student did not have too much trouble with quantitative questions, but she did have some trouble with conceptually understanding the topics. She felt more comfortable with the material after we went over the worksheet."
"The student and I worked on phase diagrams and how to determine whether the solution is solid, liquid, or gas based on the temperature and pressure. We looked at phase changes and the term used, for example, sublimation is the change from solid to gas. We worked on writing and balancing chemical equations and using the equation to calculate grams, moles, volume, and molarity. We also worked on titration calculations."
