Here is instructions for an experiment to indirectly measure the mass of a bolt. There is a whodunit element to the exercise in that the instructions do not give clear directions as how to go about measuring the mass since the bolt is attached to a nut that cannot be removed. A number of hints are provided in the copy and also suggestions on determining the mass using a balance beam or an analytical balance. The choice of method and equipment to use is largely left to the discretion of the student with only the goals being stated and a few focus questions being asked to help establish the direction in which to move the experiment. Give it a try and pop your answer in the comments below.
