Build a wheel and axle

Science

• The student learned about simple machines and how the wheel and axle function as a simple machine to make work easier.
• By building the wheel and axle, the student gained hands-on experience with the concept of mechanical advantage, understanding how the size of the wheel and axle affects force and distance.
• The activity fostered critical thinking and problem-solving skills as the student had to figure out how to make the wheel and axle spin smoothly.

Encourage continued development by asking the student to think of other everyday objects that use the wheel and axle principle, such as a doorknob or a bike. Encourage them to explore other simple machines and build more complex projects using a variety of materials.
