physics models for exhibition
A hydraulic crane is a machine used to lift and move heavy objects using hydraulic pressure. This hydraulic crane working model is a simple DIY science project made using cardboard, syringes, and plastic tubes. It is an excellent project for school science exhibitions because it demonstrates the principle of hydraulics and Pascal’s Law in a … Read more
An earthquake working model is an exciting and educational science project that helps students understand how earthquakes occur and how vibrations affect buildings and structures. This project is simple to make at home using low-cost materials and is perfect for school science exhibitions. The model demonstrates the concept of seismic waves and earthquake-resistant structures in … Read more
Good morning everyone.Today I am going to explain my science exhibition project on “Electric Circuit Working Model.” This is a simple DIY project that demonstrates how electricity flows in a closed circuit to light a bulb. An electric circuit is a path through which electric current flows from a power source to an electrical device … Read more
Good morning everyone.Today I am going to explain my science exhibition project on “Air Cooler Working Model.” This is a simple DIY summer project that demonstrates how an air cooler works using airflow, water, and cooling principles. Air coolers are commonly used during summer to reduce room temperature and provide cool air. This project helps … Read more
Introduction An electric bell is a common device used in schools, offices, and homes to produce a sound signal when activated. It works on the principle of electromagnetism, where electric current creates a magnetic field that attracts a metallic hammer to strike a bell or steel plate. The electric bell is an important example of … Read more
