Physics and chemistry are not difficult. It's a reasoning and logic to acquire. In case of difficulties React quickly so as not to allow the gaps to accumulate: with a little will remediation is always possible.

I am a principal teacher of physics chemistry with a long experience in teaching the French system and the Tunisian system which allowed me to devote myself to the regular follow-up of students in difficulty or wanting to excel.
I offer personalized tutoring according to the needs of the student to allow the student to remedy his shortcomings and acquire the right methodology + enrich his knowledge.
courses for all levels from high school to high school (different sections)
for each session I make sure that the student has assimilated the previous knowledge and revised his homework and then begins a new part of the course: explanation, summaries and exercises of applications. Before each test, we prepare different exams and I make sure that the student has assimilated all the knowledge.
In case of previous difficulties I make sure to remedy these shortcomings and catch up.
the schedules are flexible and the courses are personalized.
Thanks to the courses I teach, you will quickly see that physics and chemistry are not difficult. It is intellectual gymnastics, reasoning and logic to be acquired. React quickly in the event of difficulties so as not to allow the gaps to be added: remediation will be all the easier.
My mission is to help the learner j to take off his notes by overcoming his difficulties and in particular by gaining self-confidence.

When I was a young child, I believed I was not a mathematical person.

It wasn't until I met an amazing teacher at age 15 that I discovered my mathematical genius and my life was changed forever.

I'm eternally grateful to that teacher.

My teacher knew that self-image and self-belief is the key to unlocking your child's mathematical abilities.

Everyone is good at maths, but we all have different styles of thinking.

Bad teachers teach every child the same way.

My job is to find your child's style of mathematics and allow him to discover that for himself.

When he discovers that, he will begin to enjoy the beauty and power of mathematics...and then you will see as the grades begin to soar.

🧪 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.

Currently a third-year engineering student at ESILV after a preparatory class in Mathematics and Physics, I offer private lessons tailored to the needs of each student.
I can tutor middle school and high school students in mathematics, physics, computer science, as well as history, French, philosophy, and Spanish. I also offer advanced courses in mathematics, physics, and computer science.

My teaching method is based on a structured and proven approach, which I developed and refined during the private lessons I gave in preparatory classes.
First session: reading and understanding the lesson, creating a summary sheet, application exercises, then exercises to do for the next session.
Subsequent sessions: quick oral review based on the completed worksheet, detailed correction of exercises and further exploration of key concepts.
This method allows the student to consolidate their foundations, gain rigor and autonomy, while progressing effectively.
