Using a globe and tracing (or wax) paper—notebook paper works with an illuminated globe—trace outlines of North America, South America, and Greenland. You can do this quickly; a rough outline showing size and shape is sufficient. Using a globe and your tracings, compare the relative sizes of North America, South America, and Greenland. Which is larger and by approximately how many times? Describe your observations.

What will be an ideal response?


North America is larger than Greenland by eleven times, and South America is over eight times larger than Greenland. North America is roughly 25% larger than South America.
