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
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
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
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
“This model shows the natural Water Cycle that occurs on Earth. Water evaporates from oceans and rivers due to the sun’s heat, condenses to form clouds, then falls as rain or snow (precipitation), and finally collects in rivers, lakes, and oceans. This cycle is essential for life on Earth.” This model creatively demonstrates the four … Read more
