Recent Tutoring Session Reviews
"We started by working through his review worksheet for physics. The main principles covered by the work sheet included density and pressure. One of the questions asked about how water forms surface tension. We spent some time reviewing valence electrons, how valence shells fill with electrons, how bonds are formed by the sharing of electron, and how polar bonds are formed. Because the hydrogen-oxygen bond in water is polar, the overall molecule has regions of positive and negative charge. These regions pair up with other molecules creating an electrostatic bond between the two water molecules. The presence of millions of these bonds is the reason for water surface tension."
"Tonight's session was geared toward preparing the student for her retake of the last test. Although she scored well on her test last week, she wanted to score higher to secure an "A" for the quarter. We looked at problems that were missed on the initial test. These problems were mostly concept questions dealing with Newton's first, second, and third laws. We reviewed these laws and created four rules to analyze the question with. Basically any concept question that the teacher will give her, she can think about the four rules we created and answer the question. The rules were a simple breakdown of Newton's laws. We also looked at drawing force diagrams. We refreshed our memories about the rules for drawing them by stating that gravity always acts toward the center of the Earth, the normal force is always perpendicular to the surface, and the frictional force is always opposing motion. We also gave a rule for rotating the axis problems. We said the x-axis is to always be drawn parallel to the surface, and the y-axis is to be drawn perpendicular to the surface. Overall, I am confident that she will improve her score. She knows her material well and only needs the confidence boost."
"The student and I worked on the properties of reflections and refractions of light off of a mirror or though a lens/water. We began discussing a lab he had done in class, where they shined a laser through water. We analyzed his data, and determined the relationship between the angle of incidence and the angle of refraction. We continued with a packet on reflections, and examined multiple examples of images viewed in mirrors. For this, we mainly used a geometric approach, focusing on the angles of incidence and refraction and using them to draw the rays. These topics have been of great interest to him, and he has shown thoughtful extensions beyond the questions on his homework."
