Create a clean, educational schematic diagram of a Rube Goldberg machine for Grade 8–9 students. Side view, left-to-right layout on a long rectangular base. Step 1: a push-button switch connected to a battery powers a solenoid pulling a small lever. Step 2: the lever releases a marble. Step 3: the marble rolls down a cardboard inclined plane. Step 4: the marble lands in a cup attached to a wheel and axle. Step 5: string wrapped around the axle goes over a pulley and lifts a small container. Step 6: the container slowly fills with dripping sand or water as a one-minute time delay. Step 7: the tipping container pushes a triangular wedge under a block. Step 8: the lifted block turns a horizontal screw that pushes a sliding platform forward. Step 9: the platform presses a final lever switch. Step 10: a battery-powered LED light turns on. Use simple materials like cardboard, popsicle sticks, string, marbles, and plastic bottles. Label each step and each simple machine. Clean line-art style, instructional diagram, white background.
