There is need for elementary experiments in which the “research spirit” is present. Such an experiment involving the measurement of low temperatures has been used in both general physics and physical sciences laboratories. Each pair of students is required to devise its own method for measuring the temperature of a dry ice-alcohol mixture, to design and construct its apparatus, to carry out the measurement, and to report back to the whole group at the close of the laboratory period the following week. Stronger student motivation and insight into basic factors involved in experimental procedure have been among the outcomes of this experiment.
