Recent Tutoring Session Reviews
"The student and I spent half the session working through his chemistry review packet and the other half on his physics review packet. He is still doing well in the class."
"We ended up covering Lewis structures and covalent bonding, and I showed the student a set of rules in which she will never get an incorrect Lewis structure. One thing that she will have to remember is that once you count the valence electrons from the atoms itself, in doing a Lewis structure from that point, you are only worried about completing the octet around the outside atoms. From this point, we then did molecular shapes and electron geometries from Lewis structures, and I showed her how the shape is generated to make a table of shapes. We then used this information to talk about polarity and that if an atom has a Lewis structure where a pull is different in any direction then the molecule is polar. She ended up scoring 100% with her test over parts that we had discussed about Hess' Law. I also gave her a little additional practice with the Lewis structures, bonding, and quantum numbers for her final on Tuesday."
"For this session, we covered miscellaneous topics that she has missed in class such as Snell's Law of Refraction and other equations pertaining to refraction. We also went over the light spectrum and the correlation of frequency and wavelength to the speed of light."
"Went over more practice for her final on mixtures and enthalpy of phase changes. This was our last session, and she has made great improvement."
"Today the student and I completed the study guide her biology teacher gave her on evolution, ecology, and the body systems. She knew many of the vocabulary words that were on the study guide and knew the body systems very well too! She was able to answer many of the questions on evolution and ecology but said she was having difficulty with other areas that will be covered on her final such as the structures of plants, the Calvin cycle, and the nitrogen and carbon cycles. As she finds this material challenging, I have decided to make her a summary of this material that we will go over together on Monday."
"We covered hybridization and IUPAC naming rules for naming alkanes. We talked specifically about sp3, sp2, and sp hybridized carbons and how the unhybridized p orbitals form pi bonds in double and triple bond carbon compounds. I told the student to determine the hybridization state of a carbon by counting the number of sigma bonds. I will send him some practice problems on hybridization and IUPAC alkane naming after today's session to discuss at our next meeting."
