A wind vane is a device used to show the direction of the wind. It is also called a weather vane. Wind vanes are usually placed on rooftops, towers, or poles, where the wind can blow freely. How it works: This simple wind vane model shows how we can measure wind direction using basic materials. … Read more
This model demonstrates how a greenhouse creates a controlled environment to help plants grow. It traps heat from sunlight using a transparent cover, maintaining a warm and moist atmosphere inside. Greenhouses are used in agriculture to grow plants even in cold weather or poor soil conditions. This DIY model shows the greenhouse effect, temperature control, … Read more

This project will demonstrate a volcanic eruption using waste papers, glue, paint, a plastic bottle for the eruption effect with smoke. 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 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. Materials Required: Cardboard (for base and structure)LED Lights (for Sun and Earth’s illumination)DC Motor (for rotating Earth)Small Plastic Ball (for … Read more
This project will demonstrate the solar system using LED lights, a rotating mechanism (optional), and materials like cardboard, color paper, and small balls. The LED lights will represent the Sun and planets to make the model interactive and visually appealing. Materials Required: Cardboard (Base & Background) – For mounting the planetsColor Paper/Paint – For decorating … 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
