how to make automatic barrier gate working model

automatic barrier gate system working mdoel for science project exhibition - diy - science project academy

An automatic barrier gate operates using a DC motor and a rotating arm, controlled manually or with sensors. It’s used to restrict or allow vehicle access in areas like parking zones or railway crossings. This model shows how an automatic barrier gate works using a DC motor to control the movement of the gate arm. … Read more

how to make hydraulic crane working model

hydraulic crane working model for science project exhibition - diy - science project academy

This model demonstrates how hydraulic pressure can lift heavy objects using syringes filled with water—mimicking how real cranes operate in construction and industries. This hydraulic crane works on Pascal’s Law, which states that pressure applied to a fluid is transmitted equally in all directions. The syringes use water to transfer pressure, which moves the crane’s … Read more

How to make the water fountain(table top) working model

water fountain working model for science project exhibition - diy - innovative and creative - diypandit

This working model is a Water Fountain, demonstrating how a closed water system uses a pump to circulate water. It also helps explain concepts of pressure, water recycling, and motor-powered flow systems. Such mechanisms are used in gardens, buildings, and artificial water features. This model demonstrates a recycling water fountain using a DC water pump … Read more

how to make the hydraulic press working model

hydraulic press working model for science project exhibition - diy - diypandit

A hydraulic press is a machine that uses liquid pressure to compress or shape materials. It works on the principle of Pascal’s law, which states that pressure applied to a liquid is transmitted equally in all directions. This model uses hydraulic pressure to compress a balloon or soft object between two platforms, showing how force … Read more

how to make photosynthesis working model

photosynthesis working model for science project exhibition - fair - diy - diypandit - biology project

Photosynthesis is the process by which green plants make their own food using sunlight, water, and carbon dioxide. It is one of the most important natural processes on Earth because it provides food and oxygen for all living beings. In photosynthesis, plants take carbon dioxide from the air and water from the soil. The chlorophyll … Read more
