Simple Machines - Screw

The Simple Machines Screw model offers a clear and effective way to teach how rotational motion becomes linear force. Made from high-quality wood and metal, this model is easy to manipulate and features a large block-mounted square handle-ideal for young learners. It helps students understand how threads and rotation create upward or downward movement with minimal effort.

Educational benefits:

• Visualises one of the six classical simple machines in action
• Builds understanding of force, thread mechanics, and torque
• Strengthens fine motor skills and mechanical reasoning
• Great for both hands-on inquiry and teacher-led demonstration

Classroom activity ideas:

• Compare effort required for different screw rotations
• Predict how far the screw will travel with one full turn
• Explore real-world applications like clamps or bottle caps
• Use the model to study thread pitch and its influence on force
