Where students can do themselves step by step for their school exhibition or fair
1. Introduction Good morning, respected judges, teachers, and my dear friends. Today, I am going to explain my science project, Automatic Rain Cloth Collector Working Model. Have you ever experienced a situation where clothes kept outside for drying become wet because of sudden rain? To solve this problem, I have designed an automatic rain cloth … Read more
Science exhibitions and the prestigious INSPIRE Award – MANAK scheme encourage young innovators to build working models that solve real-world problems through technology. Among various domains, sensor-based electronics projects stand out for their practicality, automation capabilities, and potential for high competition scores. Sensors serve as the bridge between physical environments and electronic systems, enabling automation … Read more
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
