24€Electrochemistry: This class introduces students to the principles of electrochemistry, focusing on redox reactions and galvanic cell.
Trusted teacher: 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.

17€PUBLIC SPEAKING LESSONS TO BOOST YOUR COMMUNICATION PUBLICLY 💪😊🏆
Trusted teacher: Public speaking skills is essential to anyone who wish to express their feelings and thoughts to any form of audience. Why is it important, 1)It boosts one's confidence in communication 2) As a leader in any team , public speaking skills is a must as it builds strong bonds and trust by your subordinates. 3) It calms all forms of unsettlement due to underlying issues which could be, no funds by the company to pay off worker's salaries.A leader with public speaking skills glabs the worker's attention by giving them hope and why there could be delayment in salary disbursement.That avoids/prevents panic to the workers 4) As leaders-parents who knows how to engage their kids in family affairs tends to build strong bonds 5) It is a driving force that could make one come out of the shell and become a global personnel e.g "Sir Isaac Newton" who was an introvert but ended up coming out of the shell. E.T.C This class is aimed for both introverts and extroverts. Various approaches are going to be used tailored to meet the need of one's personality.The goal is to awaken the public speaking giant in someone.That will end up making a person (either introvert or extrovert) an excellent public speaker . That's the goal for this class-"Public speaking lessons." The class includes most of the age groups from 3 years up to 70 years. Book the lesson and become the best public speaker 😊💪🏆

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.
