Dear Parents and Supervising Adults, This specialized kit makes it possible to investigate how natural resources such as wind can be used in Gigo mechanism by assembling each model to produce energy, or by transforming them from one form to another.
CHECK IT OUT 1. Formation of Wind How is “wind” formed? What are the functions of wind? How is wind utilized? The Earth’s surface is surrounded by an atmosphere. Solar radiation is constantly landing on and passing through the atmosphere before it reaches the Earth. Because the Earth spins at an angle, different regions are subjected to different levels of solar heat.

CHECK IT OUT Wind Force Scale The wind force can be measured by observing the sea or land condition under wind effects, and represented based on the wind force scale. At present, the most common scale used internationally is the Beaufort Scale, which was created in 1805 by Sir Francis Beaufort, an Irish-born British admiral.

Eddies and vortices in the air near a moving body lower efficiency. The shape of the wing in Gigo’s long and windmill blades all follow the principles described here, and these are taken from a the science of fluid mechanics.

CHECK IT OUT 6. Reverse Generator with Wire Connector Fig. 13 30X MOTOR WITH WIRE CONNECTOR Generator Axle In this experiment, we use a special generator component, as shown in Figure 13. On its most right side, an axle is placed to rotate the input fans, and then the wind power generated by the fans will be transmitted via the gear A, B, C and D to the generator.

SETTING UP THE WINDMILLS Outdoors Fixing the windmill on a bamboo rod with 2 CABLE TIE (Fig. 34). Fastening the CABLE TIE to ensure the windmill is immovable (Fig. 35). Fig. 34 Fig. 35 Indoors Press the Gearbox with your hand (Fig. 36) while fixing the windmill base to the ground with tapes (Fig. 37). Putting two iron blocks or stones with the weight of 1.3 Kgs for each on the base to further fix the windmill (Fig.
LET’S DO SOME EXPERIMENTS! Experiment 1: Adjust the Gear Ratio of Gigo Gearbox Use a windmill with SHORT BLADE (Fig. 42) to observe the variation of power generation (the brightness of the LED bulb) under the same wind speed. Fix the angles of the blades and change the gear ratios by shifting the gears at the lower axle.
STORING THE GENERATED ELECTRICITY With the Following Experiment, a Mini Power Plant Can be Built. Fig. 45 Make sure the switch on the 1.5V DUAL BATTERY To activate the windmill, toggle the switch to OUT BOX is set to IN (charge). (discharge).
ADVANCED REFERENCE Fig. 47 5. When set to OUT, the 1.5V DUAL BATTERY BOX will discharge and activate the windmill in case there is no wind. 6. Interestingly, the fast-rotating windmill slows down when rechargeable batteries are inserted. It is a normal phenomenon because the flat batteries constitute an ultra high capacitance.
