I am a qualified engineer from Arts et Métiers ParisTech and followed a preparatory class, accumulating more than 10 years of experience as a private mathematics teacher. My goal is to help your child reach their full academic potential in mathematics and develop skills that will prepare them for a bright future.

Why choose my courses?

Would you like your child to:

Significantly improve your results in mathematics/physics-chemistry?
Join a selective curriculum?
Become independent and confident in your abilities?
Over the last 5 years, I have had the privilege of supporting more than 30 French students, from middle school (sixth, fifth, fourth, third) to high school (second, first, terminale), towards academic success. My students obtained good averages, passed the certificate, the baccalaureate and the preparatory classes, while strengthening their self-confidence.

My teaching method in 3 steps:

Short term: Immediate improvement in average by assimilating the course and preparing for assessments. This includes assimilating the course, taking notes, practicing standard exercises, anticipating teachers' expectations and test questions, as well as acquiring writing methods.

Medium term: Integration of reasoning and working methods. Your child will learn to work regularly in this order: assimilation, training exercises, preparation for assessments and analysis of results.

Long term: Establishing clear goals, building the steps to achieve them, realizing the SIMPLICITY of mathematics, building confidence in your abilities and unlocking your child's potential.

Details of the formula:

One to two sessions of 1h30/2h per week to assimilate the course and prepare for the evaluations.
Classes delivered via Google Meet for effective online learning.
Use of a virtual whiteboard to facilitate the assimilation of concepts.
Access to an online library including 10 mathematics reference books.
Over 1000 online exercises to strengthen math skills.

If you read this BRAVO, you have just taken a big step towards improving your level in Maths, Physics and / or Chemistry.

Holder of a license in Applied Physics from the University of Sciences and Technologies of Montpellier and a Master in Medical Life Engineering from the University of Paris Descartes, I offer to accompany you throughout the year or for more punctual sessions (Preparation for exams or questions) or for awakening to basic sciences. Holder of the Certificate of Aptitude for Functions of Facilitator (BAFA) I am also a pedagogue and know how to adapt to your possibilities to find your way of learning and your pace of work. There are many ways to understand these subjects but there is always one that will suit us best.

During my three years of Applied Physics my teachers taught me intuitive techniques to preview the results, know what to find and where we are going. I therefore suggest that you explain the classic, institutional way, but also give you the secrets that we do not teach.

For more information, do not hesitate to contact me.

🧪 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.

Lesson: Electrochemistry
Duration: 60 minutes
Grade Level: Advanced Science / Chemistry (IGCSE, A Level, IB)
Main Objectives:
By the end of this lesson, students should be able to:
1. Define electrochemistry and explain its importance.
2. Describe the difference between electrolytic and galvanic (voltaic) cells.
3. Write half-reactions and overall cell reactions.
4. Calculate standard electrode potentials and predict the direction of electron flow.
5. Understand practical applications of electrochemistry in everyday life.

Lesson Outline / Brief Notes:

1. Introduction to Electrochemistry (10 minutes)
Definition: Electrochemistry is the branch of chemistry that deals with the relationship between chemical reactions and electricity.
Key Concept: Redox reactions involve the transfer of electrons.
Real-life example: Batteries, electroplating, corrosion prevention.
2. Galvanic (Voltaic) Cells (15 minutes)
Composed of two half-cells connected by a salt bridge.
Oxidation occurs at the anode, reduction at the cathode.
Example: Daniell cell
Zn(s) | Zn2+(aq) || Cu2+(aq) | Cu(s)
Oxidation: Zn → Zn2+ + 2e−
Reduction: Cu2+ + 2e− → Cu
3. Electrolytic Cells (10 minutes)
Require an external power source to drive non-spontaneous reactions.
Example: Electrolysis of molten NaCl
At cathode: Na+ + e− → Na
At anode: 2Cl− → Cl2 + 2e-
4. Standard Electrode Potentials (10 minutes)
Electrode potential measures the tendency of a species to be reduced.
Example:
Zn2+/Zn: -0.76 V
Cu2+/Cu: +0.34 V
Predict electron flow: Electrons flow from Zn to Cu in a Daniell cell.
5. Applications of Electrochemistry (5 minutes)
Batteries (Li-ion, lead-acid)
Electroplating (silver plating, chromium plating)
Corrosion protection (galvanization)
Exercise (10 minutes)
1. Short Answer Questions:
a. Define electrochemistry.
b. Identify the anode and cathode in a zinc-copper galvanic cell.
c. Explain the difference between galvanic and electrolytic cells.
2. Calculation:
Given:
Zn2+/Zn: -0.76 V
Cu2+/Cu: +0.34 V
Calculate the standard cell potential of a Daniell cell.
3. Application Question:
Describe one practical application of electrochemistry in everyday life and explain how it works.
