Recent Tutoring Session Reviews
"The student and I reviewed topics which would appear on his chemistry exam the following week. His teacher was extremely specific in instructing her students about the scientifically appropriate method for which to measure with regards to PV (place value) and SF (significant figures). We reviewed how to read several instruments, including a ruler (analog tool) as well as a scale (digital tool) and that significant figures applies to the ruler whereas place values apply to the digital scale. We continued by reviewing more about the rules of addition and multiplication when considering error, and that when you multiply, your answer must be expressed in terms of the correct amount of significant figures, but when you add or subtract, your answer needs to be expressed in terms of the right place value. We went on to other vocabulary words such as "dimensional analysis" and "physical science." I encouraged him to 'follow the units' in chemistry, and that often you need to combine units in ways you know they are related in order to get the correct answer. For instance, if you are given the number of atoms of a substance contained in a cube, you can compute the density of the material by converting the number of atoms to the total weight of them and converting the dimensions of the cube into the volume, then dividing the mass by the volume in order to obtain density. We also reviewed the volume of spheres to cubes, and found out that 100 marbles with a total volume of 1mL will not fit into a 100mL container. If the marbles however had a diameter of 1cm, then more than 100 could fit into the container. He and I then briefly reviewed for his algebra I test upcoming during the following week. The test was mostly on exercises with the line equation, and so we practiced finding the x and y intercepts, and the constant 'b.' He was proficient as doing this by the end of class. Rating 4/5 stars."
"The student's science class is switching from physics to chemistry. We reviewed a lot of basic chemistry including molar mass, molar conversions, stoichiometry, and molecular and empirical formulas."
"Topics: activity chemistry, acid and base chemistry. Progress: worked through practice problems for an upcoming test."
