This Human Respiratory System Working Model is an excellent biology science exhibition project that demonstrates how breathing takes place in the human body. The model can be made using balloons, transparent pipes, cardboard, straws, and simple craft materials. The main working principle is based on the movement of air into and out of the lungs … Read more
An Automated Irrigation System using a Soil Moisture Sensor is a simple and useful science exhibition project that demonstrates how technology can be used to water plants automatically. The main purpose of this model is to supply water to a plant whenever the soil becomes dry and stop watering when sufficient moisture is detected. This … Read more
This Water Cycle 3D Working Model demonstrates the major stages of the natural water cycle—evaporation, condensation, precipitation, collection, and runoff—using a small humidifier and a DC water pump. It is suitable for a school science exhibition because the processes can be demonstrated visibly. Materials Required Step 1: Prepare the Base Take a strong cardboard or … Read more
Introduction “Good morning, respected judges. Today, I am proud to present our project: the Smart Automatic Car Parking and Toll Gate System. As global urban centers expand, traffic congestion at entry points like parking garages, malls, and toll plazas continues to escalate. Traditional manual boom barriers rely heavily on human operators, leading to slow processing … Read more
Introduction “Good morning, respected judges. Today, I am proud to present our project: a Smart, Non-Programmable Fire Fighting Robot. Fire disasters strike unexpectedly, causing devastating losses to life and property. Deploying human firefighters into intensely toxic, high-temperature environments is highly hazardous. While micro-controller-based autonomous robots exist, they are often complex to program, expensive to manufacture, … Read more
