"We went over balancing chemical equations and classifying them. She struggled a bit with writing net ionic equations and identifying what the products of a reaction would be based on what reactants are used. She had a general knowledge of what was going on and what she needed to do, but it didn't look like she had very much practice with the problems. I included some strategies on net ionic equations and balancing equations. I did not leave her with any extra practice, I think she had plenty of problems to do both in the extra practice and in the chapter assessments. I did not see any scores or grades to note progress. The only thing I think that she could improve on is familiarizing herself with the common ions and charges that they carry; a lot of the time, she has to look at her ion sheet for the simple ions like hydrogen or sodium. If she knew these off the top of her head, it would greatly reduce the time she needed to spend on these problems. I think that the way she was taught was to look at the cheat sheet that the teacher gave her instead of the periodic table, so I will try to incorporate this into the next time that we work on chemistry."
"We primarily focused on chemistry, specifically on stoichiometry and converting grams to moles using molar ratios and converting back to grams of product. The student quickly caught on to the concepts and should do well with a little more practice. We finished with a review of algebra homework. We reviewed substitution of variables, solving for multiple variables by graphing, and had a review of consistent, inconsistent, and dependent equations."
"Today the student and I went over stoichiometry, limiting and excess reagents, percent yield, percent composition, and math involving chemical reactions, moles, grams, and grams/mole. We also went over the differences between chemical and empirical formulas. I helped the student to step back from the math and lay out a plan to attack rather than letting the math guide him to his answer."
"Last night and tonight we reviewed some questions on the student's homework assignment. Both of the homework assignments dealt with determining the amount of energy that is given off in a reaction and how this affects either the amount of calories burned during exercise or the change in temperature of a mixture."
"In this session we worked on reaction rates and the theories behind them. We also looked at diagrams related to reaction rate and rate laws. The student did well with these. She understands the problems more conceptually than mathematically, which is very good, but with more complicated problems a mathematical understanding will be important."
"We continued our review for the student's chemistry exam. We continued with balancing chemical equations, which he has made considerable improvement on. He's really starting to get the hang of this. We will move on to new concepts in our next session. 1. Balancing chemical equations, 2. Molecules, and 3. Molecular formulas."
