# Scale Activity Part 2

show/hide **words to know**

**Meter:**a unit of length equal to 100 centimeters or 39.37 inches. A meter is also about the same length as a yard.

**Millimeter:**a unit of length that is one thousandth the size of a meter, and one tenth size of a centimeter.**Simulate:**to look like, take the shape of, or sound like something else; imitate.

## Scale Activity Part 2

Now that we know how large a one inch line becomes when we magnify it one hundred thousand times (100,000 X), what would happen if we magnify the same line a billion times (1,000,000,000 X)?

Continent | Area (milesĀ²) | Area (kilometersĀ²) |

Africa | 11,725,922 | 30,370,000 |

Australia | 2,934,376 | 7,600,000 |

Europe | 3,930,520 | 10,180,000 |

North America | 9,455,642 | 24,490,000 |

South America | 6,888,062 | 17,840,000 |

**Here is an activity for you.**

If you have followed the two mathematic activities it becomes clear that changing the size of things can have a very big impact. However, the biggest impact is still to be calculated. If the nano world is actually one billion times smaller than a meter, to get an idea of the reverse you need to calculate the size of a one meter line magnified one billion times.

Take a line one meter long by one millimeter wide. Calculate how big this line would be if we magnified it one billion times. Then, answer these questions:

How many times could the line go back a forth between the Earth and the Moon?

How many Earths could you cover with the magnified line if were carpet?
