Build a Hydraulic Excavator
Assemble a wooden excavator model with a jointed arm and bucket. This DIY STEM engineering kit makes construction machinery an exciting subject for hands-on discovery.

Control the Moving Arm
Explore the syringe controls and clear tubing as you operate the model. Observe how hydraulic pressure transfers movement between connected parts of the excavator arm.

Solve, Adjust and Explore
Fit the pieces, examine the joints and test the arm's movement. Building this science model encourages patient observation, focused assembly and practical problem-solving conversations.
