Recent Tutoring Session Reviews
"The student and I spent this session preparing for her upcoming chemistry test. Last week, we continued to practice electron configuration diagrams and got a head start of trends in the periodic table. Today was mostly about helping her recall the information we had already gone over, especially the vocabulary. We went over each of the scientists and their contributions to the field of chemistry, as well as the different models of the atom. We went over the associated equations for wavelengths, frequency, and energy, but didn't spend too much time because she completely has this concept down. We also practiced some electron configuration abbreviations with noble gases. We broke each of trend down vertically and horizontally and compared them to one another. Once we did that, I had the student do some practice problems (putting elements in order by electronegativity, size, etc.), and she did very well. Overall, I think she is very prepared. I gave her some tips to fill out her "cheat sheet" note card that her teacher was allowing to be used during the test. She also felt much more confident in her abilities once we had finished up."
"We did more work on ideal gas laws, as in our last session. The problems used Charles' Law, Boyle's Law, the Ideal Gas Law, and different forms of the gas constant. The student did well with the material. She has a test coming up."
"This session the student and I started out by reviewing the material from last week which included quantum numbers which we learned in more detail and we also reviewed radioactivity. We then moved on to study gas laws which is the material that she is going over in her class right now. We learned about the properties of gas molecules such as Brownian motion, their high speed, their perfectly elastic collisions, and their ability to not stick to each other. We continued by learning more about the ideal gas law PV=nRT which we then broke down into different classifications: Boyle's law, Avogadro's law, and Charles' law. I told her that these were all just different subsets of the ideal gas law and told her how to approach any ideal gas law problem. In this way, she won't have to do too much memorizing as to what variables are kept constant in each of these three cases. We then moved on to a practice test that she had done. During the process of going over this, she learned a lot of more material. One large topic we went over was the idea of activation energy, heat of formation, endothermic, and exothermic reactions. We looked at energy of reaction curves to see how we could label each of these things and talked about examples of each. We looked at how equations are typically written and how they actually work. She did extremely well with this topic. Another large topic that we went over was solubility. She learned the vocabulary words soluble, insoluble, pure, unsaturated, saturated, and supersaturated. We looked at examples of each and answered the practice questions that she had gone over. We also learned about several smaller topics. It was an excellent class and I think the format of it was perfect."
