Answer:
My task is to create a presentation showing the powers of 2 from 2 to 2^20 and find real-world distances, temperatures, or lengths of time that are close to the power for as many powers as possible. For example, I can start by placing the following real-world examples with the correct powers of 2 in my presentation:
• The height of Fall Creek Falls, Tennessee, in feet (2^8)
• The distance to the Moon, in miles (2^11)
• The melting point of gold, in degrees Celsius (2^10).
Each of the distances, temperatures, and lengths of time should be close to a power of 2 but does not have to be equal to it. Please let me know if you need any additional information.
