Mixing Carefully: “Scientific” Jello Preparation
Length: 6+ Hours
Discipline: Physics and Astronomy
Level: Introductory (non-majors)
Author: Fornari, Marco
Introductory, non-major laboratory courses are perfectly suited to a PBL approach. In these courses, the main objective is to involve students with diverse interests in exploring the scientific method in a ‘practical’ laboratory setting. This problem has been used in a freshmen course to explore the concepts of volume and weight while learning how to perform simple measurements and how to treat errors. It is suitable for courses such as ‘Conceptual Physics’ and ‘Armchair Chemistry’. The framework of the problem is the preparation and the discussion of the properties of jello.
