A few technical difficulties has seen our plane stalled on the tarmac but all is now well and we are ready to continue our journey.
This week we move from what was once the tallest object in the world to what was, and remains to this day, the longest man made creation. Begun over 2000 years ago it took many years to complete.
The Great Wall of China was built and rebuilt many times since it was first begun around the 7th century BC. The wall was amazingly long as it twisted and turned along China’s border but very little of it still exists today.
Your task this week involves several steps.
1. Find out how long the wall was during its main construction period.
2. Find an image of the world with the city where you live at the centre. Google maps is good for this.
3. Use the map’s scale to measure out the length of the wall in a straight line.
4. Draw an arc using this distance scale to see how far the wall would stretch from your city. If you have Activstudio the compass tool would be good for this.
