Great Wall of China Model for Kids

To this day the Great Wall of China is one of the most extraordinary feats of engineering and architecture.
It is in total length, over 12,000 miles long and consists of walls, fortresses, ramparts, trenches and natural defences such as rivers, hills and mountains.
It is made up of many different sections that were built at different times throughout history.
Some stretches of the wall were built as early as the 8th to 5th centuries BCE by the ancient dynasties. Some of these disparate stretches of the wall were joined together in the Qin dynasty (220 - 206 BCE).
The early walls were built with rammed earth, gravel, wood and stone. It was very difficult to transport the vast amount of material that was required to build the walls so the builders would often use the locally available materials; in the mountains, they would quarry the available stone and, on the plains, they would use the soil to create rammed earth and gravel walls.
Later, more sophisticated walls were built by the Ming dynasty using bricks. These were smaller and easier to handle than stone or mud and so the speed of the construction process was increased.
The walls were built across the historical northern borders of ancient Chinese states to protect against the nomadic raiders of the Great Steppe.
This is the vast area to the North.
It stretches through Hungary, Bulgaria, Romania, Moldova, Ukraine, Western Russia, Siberia, Kazakhstan, Xinjiang, Mongolia, and Manchuria.
Other uses of the walls were to maintain border controls to allow for the application of duty taxes on goods transported along the Silk Road. It also allowed for the careful control of immigration and emigration.
The construction of watchtowers and garrison bases created the need for barracks, stables and armouries on the safe side of the wall. Rapid, early warning signalling was made possible by using fire and smoke from the watchtowers built on the peaks of hills and mountains. The protected, pedestrianised rampart walkways also created a transportation corridor through often, remote and difficult terrain.
Making The Model of The Wall:
To create the model we need to build a section of a mountain ridge and then top it with some structures: watchtowers, a garrison base and a fortified rampart to connect the two along the ridge..............
