Lab? You can make your own meter stick balance as shown below. Find a few trinkets from around the house and hang them into the meter stick with string or tape. You can use your kitchen scale to measure the masses of the hanging trinkets. There are two places in the lab instructions where you will need to think about your tape or string, instead of the metal "sliders" that are used in the lab. In Part A section i, you will need to figure out a good way to estimate the location of the hanging mass, measured to the nearest 1 mm, even though your tape or string might be wider than that. In Part D section i, you will need to modify your model in order to account for the mass of the hanging tape or string; however, if your tape or string is very light, you might not see much of a change to your model by accounting for the mass of the tape or string (and that's okay)
