Simple Machines - Wedge

This hands-on wooden wedge model allows students to explore one of the simplest yet most powerful mechanical tools. Wedges are used to split, lift, or hold materials in place, and this model brings those concepts to life through engaging, inquiry-based experiments. The triangular design helps learners see how slope and angle impact force, while the solid construction ensures consistent performance in classroom demonstrations.

Educational benefits:

• Demonstrates the principle of mechanical advantage through angled surfaces
• Promotes understanding of everyday applications of wedges
• Encourages students to think critically about force distribution
• Ideal for tactile learners and kinaesthetic investigations

Classroom activity ideas:

• Test different wedge angles to observe lifting force changes
• Investigate how inserting the wedge partially vs. fully affects effort
• Compare the model to real-life examples like axes and chisels
• Ask students to predict and explain the easiest method to lift a load using the wedge
