Description

The Great Pyramid of Khufu is made up from over 200 layers of horizontal limestone blocks, and the area of each layer is slightly less than the one below. The Egyptians had to be very precise when building the pyramids to get them to the shape they are. The 'bent pyramid' in Egypt gets its name because the incline changes part way up. The Egyptians used a plumb bob and a tri-square to check they were building accurately.

Classroom Ideas

Could be used as part of an activity on understanding how people lived before the resources and technology we now have available to us were invented. Pupils could be asked how they think a pyramid was made before the clip begins, writing down their ideas on a mini whiteboard, and then watch to see how accurate their predictions are. This should lead into a discussion around the difficulty involved and the talent of the early Egyptians.
