Bumper Class Pulleys Pack

A versatile pack of plastic pulleys and steel axles, perfect for D&T classroom demonstrations.


  • This comprehensive set of pulleys is designed to effectively support the teaching of mechanical systems and principles. Students can experiment with different pulley sizes to understand how variations in size affect the mechanics of lifting loads.

  • In a Key Stage 2 setting, investigate how pulleys integrate into broader mechanical systems, emphasising hands-on learning to build understanding of their impact on force application. This set aligns with the curriculum, targeting the students' ability to apply their knowledge in designing and using mechanical systems.

  • Teachers can elaborate on the functionality of pulleys in Year 5 curriculums, which study forces extensively. Demonstrations using this set will exemplify how mechanisms such as pulleys enhance the ability to manage forces effectively, fostering a deeper comprehension of scientific principles.

Supports the National Curriculum
