Constant speed and variable speed - Second year of secondary school

Translated by GoogleSee original

From 51 £ /h

First: Regular speed
It is the speed that does not change with time, meaning the body moves at the same rate all the time.

✳️ Its characteristics:
- The distance traveled is constant in each unit of time.
- The graph between distance and time is a slanted straight line.
Example: A car traveling at a speed of 60 km/h without changing.
Second: Variable speed
It is the speed that changes with time, meaning the body can speed up or slow down while moving.

✳️ Types:
- Positive acceleration: when speed increases with time.
Negative acceleration (deceleration): when the speed decreases over time.

How the body's systems work to meet the needs of living organisms - Fourth Grade - First Semester

25 £ /h

How do the body's systems work together?
- The digestive system: It digests food and converts it into simple nutrients (glucose, amino acids, fatty acids) that reach the blood to nourish the cells.
- The respiratory system: Oxygen enters the body and carbon dioxide exits, ensuring the continuation of cellular respiration within the cells.
- The circulatory system (heart and blood vessels): It transports food and oxygen to all parts of the body, and removes waste products such as carbon dioxide and urea.
- The excretory system (kidneys and skin): gets rid of waste products resulting from vital processes such as urine and sweat, in order to maintain the body's internal balance.
- The nervous system: It regulates the functioning of different organs and sends signals to control movement and respond to external stimuli.
- Muscular and skeletal system: Provides movement and support for the body, and helps protect internal organs.
- The immune system: It defends the body against microbes and foreign substances, thus maintaining health.
Summary
Each system has a specific function, but the integration of these systems is what ensures human survival. Digestion provides food, respiration provides oxygen, blood circulation delivers both to the cells, excretion removes waste, and the nervous system coordinates all of this.

Microbes - First Preparatory Grade - First Semester

38 £ /h

What are microbes?
Microbes are microscopic organisms that cannot be seen with the naked eye; some are beneficial and some are harmful.
- They are found in the air, water, soil, and on the bodies of living organisms.

🔬 Types of microbes
Viruses: The smallest living organisms, they cause diseases such as influenza and AIDS.
- Bacteria: Some are beneficial (such as yogurt bacteria), and some are harmful (such as typhoid bacteria).
- Fungi: such as yeast used in bread making, including harmful ones like a fungus that causes skin diseases.
- Protozoa: such as amoebas that cause dysentery.

🌍 Where it is found
- In the soil, water, and air.
- Inside the bodies of living organisms and on their surface.

✅ Benefits of microbes
- Production of some medicines, such as penicillin, from fungi.
- Manufacturing foods such as yogurt and cheese using beneficial bacteria.
- Analysis of organic matter and restoration of elements to the soil.

⚠️ The dangers of microbes
- It causes serious diseases such as: typhoid, dysentery, influenza.
Food spoils when it grows on it.

🛡️ Ways to prevent microbes
- Wash your hands thoroughly before and after eating.
- Keep food in the refrigerator.
- Boil or sterilize the water before drinking.
- Getting vaccinated against diseases

I am a trained French teacher with a degree in linguistics. I have been teaching since 2012 and I support candidates in improving their French and preparing for official exams.

The preparation is fully tailored to your level, the date of your exam and the skills you need to strengthen.

We are working on the different challenges:
- listening comprehension;
- understanding of written texts;
- written production;
- oral production.

The goal is not only to improve your French, but also to understand what examiners expect and to learn how to respond effectively to exam instructions.

Depending on your needs, we can work on methodology, organization of ideas, argumentation, grammar, vocabulary, time management and correction of written or oral productions.

Exercises and practice topics may be offered between lessons to track your progress and identify areas that require more work.

As the exam approaches, we can also carry out simulations under conditions close to the real test, particularly for oral production.

Before we begin, simply tell me the diploma and level you are preparing for, the scheduled date of the exam, and the difficulties you wish to work on as a priority.

I'm a native French speaker from the South of France, currently studying for a Master's in Politics & Communication at the London School of Economics (LSE).

Before coming to the UK, I spent two years in Hypokhâgne/Khâgne, France's most demanding preparatory program in literature and humanities, and was shortlisted for the entrance exams of the École Normale Supérieure de Lyon, one of France's most selective institutions. I then studied History and English at La Sorbonne in Paris, followed by a Master's in Political Science at the University of St Andrews.

Every lesson is built around your goal:

-Conversation & fluency: relaxed, engaging discussions to help you speak natural, everyday French with confidence (adults and children)
-Exam preparation: GCSE, A-level, IB, DELF/DALF, with structured lessons, practice exercises and mock oral exams
-Writing skills: grammar, written expression, essay methodology
-Homework help & school support: for pupils in British schools or French schools in London (Lycée Charles de Gaulle, etc.)

I currently teach students with very different profiles, from young children learning through conversation and games to a teacher preparing for the DELF alongside her full-time job. I adapt the pace, the materials and the method to each person.

Lessons online or in person in Chelsea, Kensington and the surrounding areas. Message me to tell me about your goals and we'll build a plan together!
