Recent Tutoring Session Reviews
"During this session, we went over the contents of the lab exercise they had completed in class last week on the Conservation of Mass in chemical reactions; specifically, they had set up 3 different chemical reactions, weighing the reactants before mixing, and weighing the products again after the reaction had settled. Their assignment for this week is a report describing and analyzing the lab exercise, so we went over the general template for scientific reporting (materials/methods, expectations/hypothesis, evidence/results, reasoning/analysis and conclusion), as well as the specific application in present case. Apart from a few issues with structure/layout, he seemed to have no trouble with the general concepts, and his analysis of the results was very accurate - in particular, he clearly formulated a specific problem with the methodology and isolated the element of human error as primary cause of the disparity between expected and observed results. We also started going over their homework for next week on the relation between the mole concept, molecular weight, and mass, as well as the conversion between them. As they will be out of school next week, I also provided him with extra practice problems of the same type and will follow up on these in our next session."
"We covered his study guide material in preparation of his test. Today we went over how to draw all the possible isomers and how to figure out reactions. He knew all the material very well. Overall, there has been a lot of improvement in his understanding of chemistry."
"We covered the mechanics of chemical kinetics today, focusing on the factors that determine the speed of a reaction (concentration of species, temperature, catalysts) plus zero, first and second order reactions. She worked several problems dealing with chemical half life and concentrations of reactants and products with time."
