| How Does a Solar Cell Work? electrode antiglare layer n-type semiconductor p-type semiconductor Load electrode electric current A solar cell is a device that uses an electronic component called a semiconductor to convert light energy into electrical energy.
Using the Solar Panel | solar power ACTIVATING THE REVERSIBLE MOTOR You can experiment to activate the reversible motor as the pictures show. Mount the adjustable solar panel on the battery holder. Connect the battery holder and reversible motor with the wire connectors.
| About the Gears The gear set contains both spur and bevel gears. This kit contains “spur gears,” which mesh in the same plane and regulate the speed or the turning direction of the shafts, and “bevel gears” (the beveled edges of the gears) which mesh together at right angles to the initial turning plane of the gears and shafts to change the plane of rotation.
About the Sprockets | solar power The power transmission in chain gear systems depends on chains instead of the direct meshing of gears. Chains must fit on the teeth of chain gears. Gears used with chains are called sprockets. The “working” diameters of the sprockets in this kit are about 10 mm (10-tooth), 20 mm (20-tooth) and 30 mm (30-tooth).
| Tips and Tricks for Building the Models Both anchor pins and joint pins can be used to join rods and frames. (Fig. 1-1) But only a joint pin can allow a rod to rotate on a frame as shown. (Fig. 1-2) Use a long axle to push the joint pin out of the rod.

| Model 1 - Steam Locomotive DID YOU KNOW... The first steam locomotive started with the combination of the steam engine and rail vehicles in 1781. The steam locomotive powers its wheels with mechanical energy generated from steam produced by heating water with burning wood or coal.
Model 1 - Steam Locomotive | solar power NOTE! 1.The long axle cannot stick out of the blue medium gear. 2.The gray rod should be kept parallel to the ground. If it is lop- sided, please rotate the front blue gear to adjust it.

| Model 2 - Bulldozer DID YOU KNOW... Benjamin Holt and Daniel Best each experimented with a variety of steam bulldozers for plowing fields in the late 1800s. In 1904, Benjamin Holt successfully developed the first steam powered bulldozer. In 1925, Holt’s company and Best’s company merged to become what is now Caterpillar Inc.

| Model 3 - Backhoe DID YOU KNOW... Early in the 16th century, Leonardo da Vinci designed a backhoe. However, the unsophisticated manufacturing technology of his time kept his backhoe design from becoming a reality. In 1835, William Otis succeeded in combining the steam engine and the mechanical hoe, and the backhoe finally became a reality.

| Model 4 - Single-Prop Plane DID YOU KNOW... The world’s first powered passenger airplane took flight in North Carolina on December 17, 1903. This airplane was named the “Flyer,” and was invented by the Wright brothers, Wilbur and Orville.

| Model 5 - Helicopter DID YOU KNOW... The concept of a helicopter can be traced back to the bamboo dragonfly, a Chinese children’s folk toy popular in 400 B.C. Turning the vertical axle of the bamboo dragonfly can make it fly.

| Model 6 - Twin-Prop Helicopter DID YOU KNOW... The twin-prop helicopter is a jumbo helicopter. Its propellers come in several styles — in series, in line, and in parallel. It can carry lots of people and hoist heavy-duty machines or goods. The CH- 47 Chinook is the most representative twin-prop helicopter, manufactured by Boeing Rotorcraft Systems.
