31€IGCSE and IB Physics, Maths and Chemistry tutoring
Trusted teacher: Tutoring for International Baccalaureate (IB) Maths AA HL/SL, Chemistry HL/SL, Physics HL/SL and for International General Certificate of Secondary Education (IGCSE) International Mathematics (0607), Additional Mathematics (0606), Physics (0625) Chemistry (0620). I aim to make sure students understand material intuitively first before delving into complicated questions and foster a friendly and patient learning environment. Instead of relying on memorising formulas, I teach students how to derive the formulas themselves, build upon their previous knowledge and use them to solve complex questions in a simple way, building their confidence in the process. To facilitate this, I use metaphors and every-day things to construct stories that help students remember concepts and relationships between them. My lessons are tailored to each student's needs, preferences and learning style so I am able to accommodate specific requests. I can help students work on improving both overall understanding of the subject as well as detailed and thorough understanding of specific topics/sub-topics. As someone who sat these exams myself, I know what the most common mistakes in each topic are, the best exam techniques and have lots of tips, tricks and resources I can share! I offer flexible scheduling, with availability during the day, early mornings, and late evenings for lessons online or in-person lessons near South Kensington. Please message me before booking so we can find a time that works for both of us! If you have any questions at all, please don't hesitate to contact me :)

24€Enthalpy Changes in Chemical Reactions; This lesson explores how chemical reactions involve energy changes that can be exo or endothermic.
Trusted teacher: Lesson Plan: Enthalpy Changes in Chemical Reactions Grade/Level: Secondary / IGCSE / AS level Duration: 60 minutes Topic: Enthalpy Changes in Reactions Lesson Objectives By the end of the lesson, students should be able to: 1. Understand that chemical reactions are accompanied by enthalpy changes, which can be exothermic or endothermic. 2. Construct and interpret reaction pathway diagrams, showing enthalpy change and activation energy. 3. Define and use key terms: standard conditions (⦵), enthalpy change of reaction (ΔHr⦵), formation (ΔHf⦵), combustion (ΔHc⦵), and neutralisation (ΔHneut⦵). Lesson Breakdown (60 minutes) 1. Introduction (5 minutes) Begin with a real-life hook: Ask: “Why does burning wood release heat, but dissolving ammonium nitrate in water feels cold?” Link to lesson: These are examples of exothermic and endothermic reactions. 2. Theory: Enthalpy Changes (10 minutes) Define enthalpy (H): The heat content of a system at constant pressure. Define enthalpy change (ΔH): Heat energy transferred during a reaction at constant pressure. Distinguish: Exothermic reaction: ΔH is negative (heat released). Endothermic reaction: ΔH is positive (heat absorbed). Give simple examples: Exothermic → combustion of methane. Endothermic → thermal decomposition of calcium carbonate. 3. Reaction Pathway Diagrams (15 minutes) Draw and explain two diagrams: Exothermic pathway: Products lower in energy than reactants, ΔH negative. Endothermic pathway: Products higher in energy than reactants, ΔH positive. Introduce activation energy (Ea):Minimum energy needed for reaction to occur. Label diagrams clearly: Reactants → peak (activation energy) → products. Highlight ΔH and Ea. 4. Standard Conditions and Key Enthalpy Terms (15 minutes) Explain standard conditions (⦵): 298 K (25°C), 101 kPa pressure, substances in standard states. Define and discuss: Standard enthalpy change of reaction (ΔHr⦵): Heat change when reaction occurs in molar quantities under standard conditions. Standard enthalpy of formation (ΔHf⦵): Heat change when 1 mole of compound is formed from its elements in their standard states. Standard enthalpy of combustion (ΔHc⦵):Heat change when 1 mole of substance is completely burnt in oxygen under standard conditions. Standard enthalpy of neutralisation (ΔHneut⦵): Heat change when an acid and alkali react to form 1 mole of water under standard conditions. Use simple examples for each (e.g., combustion of methane, formation of H2O, neutralisation of HCl with NaOH). 5. Guided Practice / Mini Activity (10 minutes) Students sketch their own reaction pathway diagrams (exothermic and endothermic). Label ΔH and Ea. Pair discussion: “Why do we still need activation energy even for exothermic reactions?” 6. Exercise (Homework / Classwork) (5 minutes) Answer the following questions: 1. State whether each reaction is exothermic or endothermic: a) Burning propane gas in oxygen. b) Photosynthesis in plants. c) Dissolving anhydrous copper(II) sulfate in water. 2. On a reaction pathway diagram: Show ΔH and Ea for an endothermic reaction. 3. Define the following terms and give one example each: a) Standard enthalpy of formation (ΔHf⦵) b) Standard enthalpy of combustion (ΔHc⦵) c) Standard enthalpy of neutralisation (ΔHneut⦵) 4. Under standard conditions, the enthalpy of combustion of methane is –890 kJ mol−1.

20€IB Chemistry, Brief Lesson Outline: The Electromagnetic Spectrum
Trusted teacher: 🧪 IB Chemistry Apprentice Lesson Plan Topic: The Electromagnetic Spectrum Level: IB Year 1 (Apprentice) Duration: 60 minutes Lesson Objectives By the end of this lesson, students should be able to: ‣ Describe the electromagnetic spectrum and identify its different regions. ‣ Understand and apply the equation c = fλ. ‣ Differentiate between a continuous spectrum and a line spectrum. ‣ Explain the concept of quantized energy in atoms. Lesson Outline Introduction (0–5 minutes) Start the lesson by asking students a few engaging questions: What are some examples of invisible light or radiation around us? Why do we wear sunscreen? Allow brief responses, then explain that all of these examples are part of the electromagnetic spectrum, which we will study today. Teaching Phase 1 – Overview of the Electromagnetic Spectrum (5–15 minutes) Introduce the electromagnetic spectrum. Explain that it is a range of all electromagnetic waves, which vary by frequency and wavelength. Emphasize that all electromagnetic waves travel at the same speed in a vacuum – the speed of light, c = 3.00 × 108 m/s. Key formula to introduce: c = fλ, where: c = speed of light f = frequency (Hz) λ = wavelength (m) Point out that high-frequency waves have short wavelengths and higher energy (like gamma rays), while low-frequency waves have long wavelengths and lower energy (like radio waves). Display a spectrum diagram showing the range from radio to gamma rays, with visible light in the center. Teaching Phase 2 – Spectrum Types: Continuous vs. Line Spectrum (15–25 minutes) Explain the difference between continuous and line spectra. A continuous spectrum** contains all wavelengths in a range, like a rainbow produced when white light passes through a prism. A line spectrum** shows only specific wavelengths or frequencies. This happens when excited electrons fall back to lower energy levels and release photons of specific energies. Explain that energy is **quantized**—electrons cannot have just any amount of energy; only specific values are allowed. Use the helium line spectrum image as an example. Real-World Examples and Class Discussion (35–45 minutes) Give students three practical examples and discuss their uses: 1. Microwaves – Used in cooking and communications. 2. Ultraviolet (UV) rays – Cause sunburn; used in sterilizing equipment. 3. Gamma rays– Used in cancer treatment and in detecting radioactive materials. Ask students: Where do you see or use electromagnetic waves in your daily life? Encourage short contributions to reinforce understanding. Student Exercises (45–55 minutes) Have students complete these three questions individually: 1. A wave has a frequency of 6.0 × 1014 Hz. Calculate its wavelength using c = 3.00 × 108 m/s. 2. Explain the difference between a continuous and line spectrum, with an example of each. 3. Why are gamma rays more dangerous to humans than radio waves? Wrap-Up and Recap (55–60 minutes) Call on a few students to briefly summarize one key thing they learned.

Narayan is a really good teacher. I urgently needed someone to teach me physics for two different medical school entrance exams. He was able to do it very fast and well. Every lesson started with him explaining a specific concept, and then he gave me practice questions to ensure that I was confident in solving them. Additionally, after every lesson, he shared his notes with me to study from them later on. I truly feel confident and prepared for my exams. Thank you so much!!
