Description

Bridging research and practice, FOSS Third Edition Modules engage students and teachers in enduring experiences that lead to deeper understanding of science and engineering concepts, as well as the natural and designed world. The Mixtures and Solutions Module for Grades 4 to 6 introduces students to the properties and behaviors of substances and changes in substances---fundamental ideas in chemistry, the study of the structure of matter and the changes or transformations that take places within those structures.

In this Mixtures and Solutions Complete Kits with 4 hands-on investigation activities, students will: make and separate mixtures using screens, filters, and evaporation; measure solids and liquids to compare the mass of a mixture to the mass of its parts; use a balance to determine relative concentration, as well as layer solutions to determine relative density (concentration); plan and conduct saturation investigations; compare the solubility of substances in water; identify an unknown substance based on the properties of solubility and crystal form; and observe and compare reactants and products of several chemical reactions.
