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.

Trusted teacher: Presentation : As a former National Education teacher and BAC examiner, I know how to make French enjoyable for struggling students who don't connect with the subject. Whether it is to explain how to make a dissertation pleasant to read, how to organize a composed commentary or read one's text clearly, distinctly and posed for an oral. French is not only a subject, French is difficult and requires effort, but these are rewarded! Method: My students have always made significant progress, going from an average of 5 per year to having an average of 14 in the French baccalaureate. My last one to send me his results went from 6 in writing and 9 in speaking to 15 in writing and 17 in speaking (EAF 2024 session). I have been preparing classes for these tests for years, I am up to date on methodology and programs. My services combine the experience of teaching French and the vivacity of a young teacher who succeeds in motivating the most recalcitrant students. My students have always made significant progress and above all, go to tests with confidence in their abilities. I adapt to your level and I give exercises to do for the next course (finish a comment, make an introductory essay ...). I am nice and enthusiastic but nevertheless serious: you will make satisfactory progress because you will work for 😉 2013-2025 Private lessons 2015-2018 Modern Literature Teacher in Middle School/High School 2015-University Paris IV, The Sorbonne License of French as a Foreign Language 2014-University Paris IV, Sorbonne Master of Medieval Studies 2012-University Paris IV, The Sorbonne License of Modern Applied Letters 2010-Brevet of Aptitude to the Functions of Animator 2008-Baccalaureate series L 2006-First Aid Training Certificate

Trusted teacher: ➤Aim of these sessions? Halfway between psychoanalysis on the one hand and American-style coaching on the other, with proposals that will be made to you according to your problem and that will have to be implemented, it will be advisable to proceed as follows: understand the mechanisms of thought & induced emotion, linked to given everyday situations and which involve blockages then act concretely through pragmatic techniques adapted to your problem, and which will be quickly proposed to you to regain power over your life thanks to the methodologies & practices of behavioral coaching. ➤This is why, choosing the appropriate mediator to carry out a quality work and help oneself to advance / overcome certain mechanisms will induce the awareness necessary for this decided change. This will then allow to register in a new dynamic in the personal & professional fields. ➤To lead this change, achieve its aspirations, improve its quality of life and develop the functioning of its cognitive, emotional or behavioral sphere, a cohort of very concrete tools and concepts are at our disposal, and which involve deepening the self-exploration. This involves questioning yourself, analyzing, taking a distance, and understanding the issues / points causing suffering, before finally freeing yourself from it. ➤Examples of topics / issues regularly addressed and which are regularly supported by a dedicated specialist coach, adapted to your plan: • Self-confidence, self-esteem and assertiveness, shyness, decision-making, assertiveness, personal development • Reduce suffering (phobia, stress, anguish, anxiety, negative thoughts, panic, depression) and modify behaviors that are detrimental to well-being (post-traumatic stress, injuries, addictions), to better manage emotions & regain life. appeasement • Concentration, procrastination, organization, professional efficiency, time management •Professional/personal relationships (family, romantic, friendly, emotional, etc.) & social: from communication difficulties generating pain & frustration to the fluidity of relationships • Professional life: tensions, pressures & conflicts, (Re) professional orientation (CV, cover letter, job interview), competitions and exams, support in a business project, teamwork ➤Each point is the subject of techniques adapted to your situation, which you will probably never have put into practice...and which have proven their worth on the people you support. ➤Thus, although involving self-exploration, coaching remains concrete in its application and bears fruit from the first sessions, since it makes people autonomous, and not dependent. ➤You will understand, specializing in life support and personal & professional projects, it is our proven skills and the positive feedback from all the people previously supported that makes us able to support you, by catalyzing the keys to your success, through a methodology and pragmatic tools, adapted to your situation. ➤And if cookie-cutter advice is not offered, that you will never be led but guided without judgment, in a process of permanent / interactive co-construction ... it is because we believe that it It is first important to analyze together, to become aware, to study jointly, to deepen, to decode your blockages and your initial problem in order to clarify your aspirations. ➤Influenced by cognitive & behavioral therapies, by Anglo-Saxon coaching instruments and the European methodology of applied psychotherapy, the approach therefore aims to seek links between current difficulties and past experiences, including repressed and unresolved conflicts and to confront difficulties which may be partially linked to inappropriate thoughts or behaviors learned / adopted often in spite of oneself. ➤ So, how does a session take place? After having identified together a problem, blockages and objectives, it is a question of analyzing them together then proposing a series of suggestions/reflections/pragmatic actions. Concretely, a session = a reflection + solutions. From the second session, 98% of our coaches say they felt a clear difference that influenced their daily lives* (2022 study). ➤ THERAPIST - COACH - PSYCHOPRACTITIONER - PSYCHOANALYST - CONSULTANT Trained at Grande Ecole post-preparatory classes & Ivy League University in the United States, our consultant teacher trainer has specialized and worked for more than 16 years, in Europe and North America, in the field, in renowned international public and private establishments, regularly speaking in forums and conferences, and also offering personalized INDIVIDUAL support, with pedagogy and meticulous methodology as the watchwords. ➤ PLACE, TIMETABLE, PRICES ✓ Locations: Geneva-Lausanne-Fribourg-Zurich-Neuchâtel-Lugano-Montreux-Basel-Neuchâtel-Bern-Lucerne-Brussels-Luxembourg-Paris-Lyon. But currently, these sessions continue to be offered by videoconference in the current context and in accordance with general demand which is almost unanimous on this subject. ✓ Indeed, apart from the classic advantages of videoconferencing (time saving related to travel & their unforeseen events, eco-responsibility, increased schedule flexibility, etc.), the quality of the session & the interaction remain identical. In addition, the entire exchange, notes and recommendations are immediately transcribed on the dedicated chat. ✓ To support us among ourselves & to be pleasant to you in this sustainable / particular period and in a spirit of solidarity, the fees are temporarily reduced and will not increase after the start of our sessions. ✓ Languages: French/English. ✓ The progress following these private sessions is perceptible from 1 to 2 sessions (*2023 study). ✓ As other people do regularly, you can also please your loved ones by offering gift vouchers available all year round.
