Learning about Egyptian Legacies Get into 4 groups Task: Complete 4 learning stations Duration: 10 minutes at each station

Activity Time: 4 learning stations Learning TaskLocation SundialLearning Station 1 Water ClockLearning Station 2 Pyramid PrecisionLearning Station 3 Google MapLearning Station 4

Summary of Stations StationAnswers Sundial Conclusion: The movement of the Sun relative to Earth enabled estimation of the time. Pro: Sundials can tell the time immediately using a simple device with no moving parts. Con: However it would not work when the sky is overcast, or at night. Water Clock Conclusion: Water escapes at a regular pace. Pro: Man used this method as it enabled reliable timekeeping, even at night. Con: It needs to be continually refilled

Summary of Stations StationAnswers Pyramid Precision 1) Researchers estimate that the Great Pyramid…. a)Was built in 23 years at most b)Required 2,500,000 stones in total and weighed 6,500,000 tons c)Had its stones delivered at the average rate of 1 per minute d)The average length of its edges was m e)The largest difference between the length of its edges was 4.4 cm (0.044 m) This means that the Pyramid formed an almost perfect SQUARE!

Summary of Stations StationAnswers Pyramid Precision f)Its original height = m g)If you multiply the average length of an edge by 2, then divide by the original height, what number do you get? h)value of pi (  ): We do not know if the Egyptians knew the value of Pi, or whether this is a coincidence. Nonetheless many people believe that Egyptian mathematics was highly advanced, and that the Pyramid shows this in many ways.

Summary of Stations StationAnswers Pyramid Precision 2) a)The base of the Pyramid is level to within m b)In other words, this gigantic structure was built on a base which was almost perfectly FLAT! 3) Based on your findings above, what conclusions can you make about the builders of the Great Pyramid? Its builders were incredibly skilled / precise / careful / advanced

Summary of Stations StationAnswers Google Maps Actual dimensions: A & B = 230 m, C = 73.5m 1.The sides of the Giza Pyramids are aligned to the four points of the compass 2.The Sphinx points east 3.The Latitude in URL is The Speed of light in a vacuum is metres per second The two numbers are similar up to the fifth digit Whether this is a coincidence, or proof of the advanced knowledge of the Egyptians, remains controversial

Thinking Time! Would we be able to build the Giza pyramid today, using the same tools as the Egyptians? Why or why not? Is the pyramid a useful legacy? Which Egyptian legacy is most useful to us today? Why so ?
