Atomic Structure 3D Model Bohr model or quantum orbital shapes (s, p, d) with LEDs. 2. Periodic Table Working Model Interactive table with lights showing groups, periods, metals/non-metals. 3. Chemical Bonding (Ionic & Covalent Bonds) 3D … Read more
Concept / Principle: This project is based on infrared motion detection — it senses changes in infrared radiation (heat) caused by a moving object like a human body.When motion is detected, it activates an LED light and a buzzer, simulating a security or automatic light system. Scientific Principle: Infrared sensors detect IR radiation emitted by … Read more
Aim / Objective: To demonstrate how dry waste collected from households and streets can be converted into electricity by burning it to produce steam, which drives a turbine-generator. Materials Required: Working Principle: Procedure: Observation: Conclusion: The waste-to-electricity model demonstrates the principle of energy conversion from dry waste to electricity.It highlights the importance of waste management, … Read more
Aim / Objective: To demonstrate the phases of the Moon and explain how the positions of the Moon, Earth, and Sun create different lunar phases as seen from Earth. Materials Required: Working Principle: Procedure: Observation: Conclusion: The model effectively demonstrates the mechanism of Moon phases.It helps students understand how the relative positions of the Sun, … Read more
Aim / Objective: To demonstrate how a two-way switch can control the operation of electrical devices like LED lights or a DC motor from two different locations. Materials Required: Working Principle: A two-way switch allows control of a circuit from two different points. Procedure: Observation: Conclusion: The model shows how two-way switches allow electrical devices … Read more
