The model will showcase how a volcano works with lava and smoke, all created with simple materials! Materials Required: Waste Paper (old newspapers or an scrap paper for the volcano structure)Glue (to bond the … Read more
This project will demonstrate both a Solar Eclipse and a Lunar Eclipse using cardboard, LED lights, thermocol balls, 9V battery, and a slow-running motor. The model will visually show how the moon, Earth, and Sun align during these natural phenomena. Materials Required: Cardboard (for base and structural support)LED Light (for the Sun)Thermocol Balls (for the … Read more
This model will demonstrate the working of the human heart, focusing on how blood flows through the heart using syringes, paint, cardboard, and aluminum foil. It will show the basic heart structure (atria, ventricles, and valves) and how the pumping action occurs. Materials Required: Cardboard (for heart structure and base)Syringes (for simulating blood flow)Aluminum foil … Read more
This model will demonstrate the cycle of day and night using LED lights and a rotating Earth model. It will show how the Earth’s rotation around the Sun causes the alternation between day and night.

This model will demonstrate how drip irrigation works using paper cups, a DC water pump, a plastic bottle, and a plastic tray. It will show how water is supplied directly to plant roots in a controlled manner, saving water and promoting efficient irrigation. Materials Required: Paper cups (to represent water tanks and plant pots)DC water … Read more
This project will demonstrate how an earthquake alarm works using cardboard, color paper, a buzzer, a 9V battery, and metal wire. The alarm will be triggered by vibrations or movement, simulating how real earthquake warning systems function. Materials Required: Cardboard (for base and structure)Color paper (for decoration and labels)Buzzer (to produce the alarm sound)9V battery … Read more
This model will compare afforestation (planting trees) and deforestation (cutting trees) using color paper, cardboard, and dried plant stems. It will effectively show the impact of human activities on forests and the environment. Materials Required: Cardboard (for the base and background)Color paper (for trees, sky, and soil)Dried plant stems (for real tree effects)Sketch pens & … Read more
This model will demonstrate how forest fires start and spread, their impact on the environment, and ways to prevent them. You will use color paper, cardboard, dried plants, and LED lights for fire effects to create a visually engaging project. Materials Required: Cardboard (for base and background)Color paper (for trees, sky, and fire effects)Paint & … Read more
