About your tutor

Hello! I’m Zeina Koolivand, an enthusiastic AP Chemistry tutor with a Master’s in Analytical Chemistry. My passion for teaching stems from a desire to demystify complex concepts and connect them to real-world applications. I believe that chemistry is not just a subject but a lens through which we can better understand the world around us. My teaching philosophy centers on creating a supportive and nurturing learning environment where students feel empowered to ask questions and explore their curiosities. Every student is unique, so I tailor my approach to meet individual learning needs and styles. By utilizing a mix of hands-on experiments, visual aids, and relatable examples, I strive to make the learning experience both engaging and memorable. I am committed to building my students’ confidence and fostering critical thinking skills. My goal is to help you grasp the material and develop a deeper appreciation for chemistry as a subject. Whether you’re in high school, college, or navigating your professional career, I’m here to guide you on your journey to success in AP Chemistry. Let’s embark on this exciting learning adventure together, and unlock your potential in the fascinating world of chemistry!

Teaching methodology

As an AP Chemistry tutor, I tailor my teaching approach to cater to students of all backgrounds, whether they are in high school, college, or adult learners returning to education. My teaching methodology is designed to be inclusive and adaptable, ensuring that every student can engage with the material at their level. Problem-Solving Focus: I emphasize problem-solving as a critical skill in chemistry. Through targeted practice, I guide students in tackling complex questions and breaking them down into manageable steps. This not only builds their confidence but also equips them with the tools to approach future challenges independently. Engagement and Interactivity: To foster a dynamic learning environment, I incorporate interactive discussions that encourage students to express their thoughts and ask questions. This dialogue helps students connect with the material on a deeper level and promotes a collaborative atmosphere where ideas can be shared and explored. Hands-On Practical Sessions: Understanding chemistry often requires a tactile approach, so I integrate hands-on experiments into my sessions whenever possible. These practical experiences not only reinforce theoretical concepts but also spark curiosity and excitement about the subject. Concept-Focused Explanations: I believe that a strong foundation in fundamental concepts is essential for success in chemistry. My detailed explanations focus on core ideas, ensuring that students understand not just how to solve problems but also the reasoning behind the methods. This depth of understanding is crucial for mastering complex topics.

Zeina tutored Ahmed on atomic structure, covering electromagnetic radiation, the Bohr model, and quantum mechanical model of the atom. They worked through a problem calculating frequency from wavelength and discussed the significance of quantum numbers in describing electron location. The next session will cover electron configuration and its relation to the periodic table.

Zeina tutored Ahmed on calorimetry and enthalpy calculations, covering both direct methods using calorimeters and indirect methods like Hess's Law and standard enthalpies of formation. They worked through examples from the textbook and discussed the greenhouse effect and hydrogen as a fuel source. Zeina assigned practice problems from the end of the chapter for Ahmed to complete before their next session.

Zeina and Ahmed reviewed thermodynamics, focusing on enthalpy (ΔH), which represents heat change at constant pressure. A positive ΔH indicates an endothermic reaction (heat absorbed), while a negative ΔH indicates an exothermic reaction (heat released). They discuss standard conditions, standard enthalpy of formation (ΔH°f), and standard enthalpy of combustion (ΔH°c). The relationship between molar mass and ΔH is explored, along with enthalpy changes for phase transitions (vaporization, condensation, melting, freezing, and sublimation). Future lessons will cover calorimetry, Hess's Law, and bond energies.

Zeina tutored Ahmed on thermochemistry, covering potential energy, the difference between heat and temperature, and the first law of thermodynamics. They discussed energy exchange between system, surroundings, and universe, focusing on volume work (W = -PΔV) and its relationship to expansion/compression. Zeina explained how to determine the signs of Q, W, and ΔE in chemical reactions, emphasizing the importance of gases in ΔV calculations. Future sessions will cover W calculations and enthalpy.
