Simple Machines - Block & Tackle

The Block and Tackle model makes it easy to understand how multiple pulleys can reduce effort in lifting. Featuring a solid wooden frame and rope system, this model is a hands-on way to explore mechanical advantage in everyday machines. Students will enjoy experimenting with different pulley setups to see how load and effort change, while building their STEM knowledge through active learning.

Educational benefits:

• Demonstrates compound pulley systems and mechanical advantage
• Encourages inquiry into force, direction, and efficiency
• Connects physics principles to real-world applications
• Supports collaborative group investigation and analysis

Classroom activity ideas:

• Compare effort needed with one vs. multiple pulleys
• Explore lift speed and distance with different setups
• Use to model real machines like cranes and hoists
• Ask students to lift classroom objects with the model and reflect on results
