Density: Layers of Liquids, This activity provides student with experiences that allow them to develop an operational definition of density, Each

Details

Students are provided liquids of different viscosity and density and asked to observe and predict, based on their observations, the relative density of each. They then test their predictions and develop an understanding of density by preparing sequences of the liquids layers. They are given values for the density of each liquid and asked to use this information to estimate the density of an unknown solid. Finally, there is an optional challenge to design and carry out an experiment to determine the density of a fourth liquid. Accommodates 2 classes, each with 6 groups of 4 students. Includes teacher guide, student sheets, assessment questions and SDS for all chemical provided.
