# how to make wheel and axle working model for science project exhibition – diy water well – simple – physics

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:

1. Cardboard sheets (for the base and supports)
2. Plastic bottle (for the wheel)
3. Chopsticks (for the axle)
4. Craft knife or scissors
5. Hot glue gun and glue sticks
6. Craft supplies for decoration (markers, stickers, etc.)

1. Prepare the Base:
• Cut a piece of cardboard to create the base of your model.
2. Create the Wheel:
• Cut the bottom part of the plastic bottle to create the wheel.
• Decorate the plastic bottle if desired.
3. Prepare the Axle:
• Use chopsticks as the axle. They will go through the wheel’s center to allow rotation.
4. 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.
5. 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.
6. 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.
7. Decoration:
• 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.
