Demonstrates a method of measuring the acceleration due to gravity. Provides an illustration of the apparatus and the data analysis. Suggests four different variations of this experiment. (YP)

Year 11 students investigated the real-world problem of whether screws are really brass. It allowed them to use the colorimeter and computer interface in a way that was easily understood and models normal practice in testing laboratories. Screws were dissolved in nitric acid and their absorbance of red light was compared with a standard curve.…
