Recent Tutoring Session Reviews
"The student scored 100 on her midterm and was very pleased about it. We started on Unit 5, which covered matter and energy. For matter, we covered pure substances vs mixtures. We discussed how to tell the difference between element and atoms, molecules and compounds, and so on. We also went into mixtures, which was categorized into homogenous and heterogenous mixtures. I explained that the easiest way to tell the difference is that homogenous was smooth while heterogenous is usually chunky. We also reviewed techniques focusing on separating mixtures, namely filtration and distillation. She had no trouble with matter, so we moved into energy. We briefly covered kinetic and potential energy. Calorimeter was what she wanted to review. I explained calorimeter to her using calories and joules and started with what they represented. We also reviewed temperature and what changes in temperature represented. She also started on the phase change diagram and the associated formulas. I explained the two types of formulas and when to use them - be it changing temperature or phases. I also taught her to watch for whether the problem asked for the answer in joules or calories. We tackled a few examples and practice problems in her workbook for extra consolidation. We will tackle formulas for gases and ideal gases next week."
"Today we reviewed for the student's Chemistry test - we went over molarity, and molality. We talked about properties of liquids and how these are affected by putting things into solution. He seemed pretty comfortable with the overall concepts here. We discussed reaction rates and how to find the overall rate of a reaction."
"I met with the student in preparation for his Physics test tomorrow. The test will cover the concepts of momentum, impulse, elastic and inelastic collisions, recoil, conservation of momentum, and average forces. This unit has less material so the student had a smaller packet to work on that she had already almost finished the last tutoring session. We finished up the last five problems, and the only issue the student had was understanding the different velocities and directions, but with a few practice problems, she was able to assign the correct orientation to the values. After finishing the packet, she did a few problems from the book. She will continue to study the equations and look over her notes for the test."
