In this article post we have given step by by video instruction on how to make the photosynthesis working model for science fair project using materials available at home easy
Creating a photosynthesis working model using a light bulb, a real plant, and cardboard is a great way to demonstrate how plants use light energy to produce food through the process of photosynthesis.
Here’s a step-by-step guide to making the model:
Materials you will need:
- Cardboard (for the base and backdrop)
- Light bulb (LED or low heat-emitting bulb)
- Lamp or light source
- Real potted plant (preferably a healthy green plant)
- Glue or adhesive
- Markers or pens (for adding details)
- Optional: Color paper (for decorating)
- Prepare the base and backdrop:
- Take a large piece of cardboard to serve as the base for your photosynthesis model.
- Cut out a backdrop from another piece of cardboard and glue it to the back of the base. You can draw a sunny outdoor scene on the backdrop to represent the natural environment.
- Position the lamp and light bulb:
- Place the lamp or light source behind the cardboard backdrop, aiming it towards the plant. The light bulb should represent the sun, the natural source of light for photosynthesis.
- Place the real plant:
- Position the real potted plant in front of the backdrop, near the light bulb. The plant should receive light from the bulb just like it would from the sun.
- Decorate the base:
- If desired, use color paper or markers to decorate the base to make it look more appealing.
- Optional: Add labels and explanations:
- Use markers or pens to add labels and brief explanations about photosynthesis, including the process of converting light energy into chemical energy (glucose) and releasing oxygen.
- Demonstrate the model:
- Turn on the light bulb (representing the sun) to provide light for the plant.
- Observe the plant over time to see how it responds to the light source.
- Explain photosynthesis:
- Explain how the plant uses light energy from the bulb, carbon dioxide from the air, and water from the soil to produce glucose and oxygen through photosynthesis.
This model provides a hands-on demonstration of the essential process that sustains life on our planet. It’s a fun and educational project to learn about photosynthesis and the importance of sunlight in the growth and development of plants.
