Use Newton Law of gravitation:
F=G*M1*M2/(R-squared)
G is 6.67 *10^-11 N*m^2/kg^2
M1 is mass of one planet
M2 is mass of other planet
R is the distance between the centers of the planets.
Get a physics book and look in the back to find the masses and radii of all the planets. Plug and chug.

Just use any chart or book (almanac, etc.) that lists characteristics of planets. One interesting point to discuss is how to interpret the surface gravity of planets without a solid surface. If you could stand on the surface of Jupiter you would weigh only 2.14 times as much as you do on Earth. You wouldn't want to exercise, but you wouldn't die right away. The reason is the inverse square characteristic of gravity. Look up the sun's surface gravity. You wouldn't survive that kind of pressure, but it isn't as much as you might think.

Or, you can just surf it up...
