The session began with an introduction to foundational chemistry concepts for PSAT preparation, specifically the mole concept and molar mass. The Student practiced applying Avogadro's number to calculate the number of molecules from moles and determining molecular masses of various compounds using the periodic table. Future lessons will adopt a general approach, incorporating notes, regular worksheets, and problem-solving, with a plan to introduce more advanced topics like gram weight and molecular mass.

The Student and Tutor focused on Chemistry, reviewing a worksheet on ionic and covalent bonds, and then delving into definitions and periodic table trends for electronegativity, electron affinity, and ionization energy. The Student's homework involves creating a consolidated diagram illustrating these periodic trends.

The Student and Tutor reviewed previous lessons on chemical bonds and introduced ionization energy. They then delved into a detailed discussion of intermolecular forces, including London dispersion, dipole-dipole, hydrogen bonding, and ion-dipole forces, and their effects on molecular properties. The session concluded by categorizing different bond types, and the Student and Tutor planned to work on a worksheet, practice questions, and further explore electronegativity, electron affinity, and ionization energy in the next class.

The session involved a detailed analysis of a scientific passage about Aquaporin 4 (AQP4) protein and its role in water conservation and renal function across different species. The Student and Tutor discussed complex biological concepts including protein expression, molecular regulation, and structural characteristics of aquaporins. The session concluded with the student addressing questions related to the text and planning for future discussions.

The Student and Tutor focused on preparing for an upcoming science test covering wavelength and scientific skills. They reviewed wave types, terminology, essential formulas, and unit conversions, practicing problem-solving. The session also touched upon experimental design variables and the diagrammatic representation of ultrasound waves.

The Student and Tutor reviewed basic chemical bonding principles, focusing on the definition and examples of covalent and ionic bonds. They delved into the distinctions between polar and non-polar covalent bonds, examining electron sharing and electronegativity differences. The Student was assigned homework to find examples for metallic and hydrogen bonds, and future sessions were planned to cover bond enthalpy and intermolecular forces.
