### How Much Would I Weigh on Mars?

Using reference materials available in the classroom or library, look
up the surface gravity of different planets and other solar system
bodies of interest (such as the moon). You may find the information
in your science textbook, an astronomy book, or an almanac. You can
also find the information about the planets at Bill Arnett's web site
The Nine Planets.
The values usually found in books are the ratio of surface gravity on
a planet to that of the earth. This makes it easy to compute your
weight. For example, if the surface gravity of planet X is 2.0 times
that of the earth and you weigh 110 pounds on earth, then you would
weigh 2*110 or 220 pounds on planet X.

After you find the relative surface gravity data, type it into a
table in a spreadsheet. Don't forget to label your data. Design
the spreadsheet so that you can enter your weight or that of a friend
into one cell and let the spreadsheet compute how much you or your
friend would weigh on the other planets.
