Create a simple balance using a ruler as the balance beam and a pencil as the fulcrum. Put 2 nickels stacked together on one side of the ruler and a single nickel on the other side so that the ruler is balanced. Does the distance from the fulcrum to the 2 nickels = 1/2 the distance to the single nickel? How would you account for any discrepancy?
