The Mysteries of the Obelisks

2. Step 1: Define the problem:
How were the Ancient Egyptians able to cut
and raise these massive obelisks?
This obelisk is 75 feet
high (3 times the height of our gym ceiling) and weighs 240 tons
(480,000 pounds)

3. Step 2: Research
Find at least two different ideas from the web and list them on your sheet.

4. Write in complete sentences.
Step 3: Formulate your
hypothesis
What is your best guess on how the Egyptians were able to raise these monuments into place?
Write in complete sentences.
Include sketches.

5. Step 4: Design an experiment
How could you test your idea using simple materials and on a smaller scale?

6. Step 5: Analyze your results.
Due to time constraints, we won’t be able to actually conduct experiments…can you find results of your experiment on the web?

7. Step 6: Conclusion of results
So, what do you think? Was your hypothesis correct? Explain!
