Step-by-Step Assembly Instructions
Step 1: Identify All Parts
Lay out all wooden plates, motor module, booster module, LED bulb, belts, screws, nuts, and wires included in the kit.
Step 2: Assemble Main Wheel Plates
Fix Plate 2 and Plate 3 onto Plate 4 using 8mm screws.
Note: Place Plate 2 in the middle layer.
Step 3: Install Long T21 Pin & Large Gear Wheel
Insert the long T21 metal pin through the large gear wheel assembly.
Step 4: Lock Gear with T21 Pin
Push the T21 pin through the center gap of the wheel assembly from Step 3 to secure the 5# wheel plate.
Step 5: Attach 6# Wooden Bracket Plate
Mount the fan-shaped 6# plate onto the wheel assembly.
Step 6: Fit Large Rubber Drive Belt
Loop the large belt around the main crank wheel gear.
Step 7: Install 7# Support Plate
Attach the triangular 7# plate to the wheel assembly as a side support.
Step 8: Build Vertical Lamp Stand (Plates 10 & 11)
Stack and fix Plate 10 and Plate 11 with 7mm screws to form the vertical bulb holder frame.
Step 9: Wire Motor & Booster Module
Connect the motor and voltage booster module with the supplied red & black wires.
Step 10: Fix Motor Assembly to Base Plate 1
Secure the wired motor module onto the cross-marked 1# base plate using 4mm screws.

4. Extended Science Knowledge: Power Generation Types
Thermal Power Plant
Burn fuel to heat water into high-pressure steam. Steam pushes turbines to rotate, converting thermal energy to mechanical energy. Turbines drive generators to turn mechanical energy into electricity.
Hydropower Plant
Flowing water spins generators to transfer energy. Dams are commonly built with stone or concrete barriers for flood control and stable water flow regulation.
Nuclear Power Plant
Nuclear fission inside reactors releases thermal energy. The heat generates steam following the same workflow as thermal power plants; the nuclear reactor replaces coal-fired boilers.
Wind Farm (Wind Power)
Uses wind force to spin turbine generators. Wind power is a clean, renewable energy source.
Tidal Power Plant
A branch of hydropower that captures energy from daily tidal water level rises and falls.
Geothermal Power Plant
Extracts heat from underground hot rock layers, hot springs, and geothermal steam as its primary energy source.
