THIS IS ALL ABOUT THE MAKING OF SCIENCE PROJECT

1. Science Investigatory Project Presentation A School-Made Electric Generator: An Experimental Application of Faraday’s Law of Electromagnetic Induction Researchers: Lord Emmanuel Real, Aira E. Guevarra, Prince Francis S. Rosales Coach/Adviser: Dr. Nellen B. Coronado TCSCS - Special Program in Science

2. Introduction Electricity is essential for modern living, yet power interruptions remain challenges in some communities. This study presents a simple, low-cost generator demonstrating electromagnetic induction and providing an educational model for energy solutions.

3. Rationale / Problem Grounded in Faraday’s Law of Electromagnetic Induction. Research Problem: How do the number of coil turns and the rotational speed influence the induced voltage and power output of a school-made generator?

4. Methodology Prototype generator with rotor magnets and copper coil. Independent Variables: 1. Number of coil turns: 300, 500, 700 2. Rotational speed (RPM): measured with tachometer Measured open-circuit voltage, current, and power output.

5. Results Increasing RPM increased voltage, confirming Faraday’s Law. At 500 turns and 400 RPM: 2.8 V At 700 turns and 400 RPM: 4.1 V Prototype successfully powered small LEDs.

6. Discussion & Conclusion 500 turns at 400 RPM gave stable voltage and better efficiency. A simple generator, when properly designed, can transform mechanical energy into electrical energy. Reinforces physics principles and provides a model for renewable, small-scale solutions.

7. Closing Science is not just theoretical—it solves real-world challenges. By applying Faraday’s Law, we created a device for education, emergency use, and future renewable prototypes. Through this, learners see how scientific principles innovate practical solutions.

8. Sample Q&A Q1: Why vary coil turns and RPM? A1: To observe induced voltage and validate Faraday’s Law. Q2: What are prototype limitations? A2: Friction, heat losses, limited magnet strength. Sufficient for LEDs only. Q3: Real-life applications? A3: Educational tool, backup power source, stepping stone to renewable systems.
