In this blog post we write about making of the wheel and axle working model for science project exhibition – diy water well – simple – physics
Creating a wheel and axle working model using cardboard, a plastic bottle, and chopsticks is a simple yet effective way to understand the mechanical principle of a wheel and axle system. Here’s how you can build this model:
Materials You’ll Need:
- Cardboard sheets (for the base and supports)
- Plastic bottle (for the wheel)
- Chopsticks (for the axle)
- Craft knife or scissors
- Hot glue gun and glue sticks
- Craft supplies for decoration (markers, stickers, etc.)

- Prepare the Base:
- Cut a piece of cardboard to create the base of your model.
- Create the Wheel:
- Cut the bottom part of the plastic bottle to create the wheel.
- Decorate the plastic bottle if desired.
- Prepare the Axle:
- Use chopsticks as the axle. They will go through the wheel’s center to allow rotation.
- Attach Supports:
- Cut and assemble cardboard pieces to create supports for the axle.
- Attach the supports to the base, leaving space for the wheel to rotate.
- Attach the Wheel and Axle:
- Insert the chopsticks through the center of the plastic bottle wheel.
- Place the chopsticks on the supports so that the wheel can rotate freely.
- Test the Model:
- Gently turn the plastic bottle wheel using the axle (chopsticks) to observe the rotation.
- The model demonstrates the mechanical advantage of the wheel and axle system.
- Decorate the model with craft supplies to make it visually appealing.
This model helps you visualize how the wheel and axle mechanism works, showcasing how a larger wheel (radius) allows for easier rotation compared to turning the axle directly. It’s a fundamental concept in mechanics and can be a great educational tool to learn about simple machines.
