To build a hydraulic excavator for a school project, start by designing a simple model using materials like cardboard or plastic for the structure and joints. Incorporate syringes filled with water or air as hydraulic cylinders to control movement; connecting them with flexible tubing will allow for lifting and lowering the excavator arm. Use a sturdy base to support the model, and ensure all parts are securely attached for stability. Finally, demonstrate the functionality by using the syringes to manipulate the arm, showcasing the principles of hydraulics in action.
