Where students can do themselves step by step for their school exhibition or fair
This is a hydraulic lift working model in a scissor shape, made using syringes and ice cream sticks/cardboard. It demonstrates Pascal’s Law, where pressure applied on a fluid in a closed container is transmitted equally.When we press one syringe, the water moves into the other, pushing it out and lifting the scissor mechanism. This model … Read more
This is a working model of the human respiratory system.The plastic bottle represents the chest cavity.The two balloons inside are our lungs, and the straws act as the trachea and bronchi.The balloon at the bottom represents the diaphragm, which plays a key role in breathing. When we pull the bottom balloon (diaphragm) downward using the … Read more
Here’s a step-by-step guide on how to connect 3 LEDs in series with a 9V battery, switch, and resistor. Materials Required: Why Connect LEDs in Series? Video Step-by-Step Instructions: 1. Connect the Switch: 2. Series Connection of LEDs: 3. Add the Resistor: https://www.youtube.com/@howtofunda
LEDs (Light Emitting Diodes) are small electronic components that glow when electric current passes through them. To connect three LEDs in parallel using a 9V battery, switch, and resistors, we follow a simple circuit design. Here’s a simple step-by-step guide to connect 3 LEDs in parallel with a 9V battery, switch, and resistors You Will … Read more
Energy is the ability to do work, and it exists in many forms. Light, wind, and sound energy are three common types we use in daily life. Light energy comes from sources like the Sun, bulbs, and lamps. It helps us see, grow plants (through photosynthesis), and even generate electricity using solar panels. Wind energy … Read more
This model demonstrates how wind energy can be converted into electrical energy using a wind turbine connected to a DC motor, which powers an LED bulb to light up a cardboard house. This model shows how wind energy is converted into electrical energy using a wind turbine connected to a DC motor. The electricity powers … Read more
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 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
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
An elevator lift is a modern machine used to carry people or goods up and down in buildings. It is also called a lift. Elevators are very useful in tall buildings, offices, hospitals, and shopping malls, where climbing stairs would be difficult or time-consuming. This model shows how a motorized elevator (lift) works using simple … Read more
A soil profile shows the different layers of soil formed over thousands of years. Each layer (called a horizon) has different composition, texture, and function: Materials Needed: Steps to Make the Model: 1. Prepare the Base: 2. Create the Soil Layers (Top to Bottom): 3. Add Details on Surface: 4. Label the Layers: Use small … Read more
The Earth is our home, and the environment is everything around us – air, water, land, plants, and animals. Sadly, human activities like pollution, deforestation, and overuse of resources are harming the environment. If we do not take care of it, the Earth will become unhealthy and unsafe for future generations. We can save the … Read more
