States of matter


This module helps students develop the concepts of “substances” and “chemical reactions.” Students see that chemical reactions enable us to make new materials by transforming the ones we have. Students model the molecular structure of solids, liquids and gases. Students use baking soda, calcium chloride and other common substances to discover that when certain substances combine, a chemical reaction takes place, and new substances are formed. Students measure the mass of substances before and after melting, dissolving, and a chemical change to investigate whether the mass is conserved during physical and chemical changes?

Disciplinary Core Idea:
PS1: Matter and Its Interactions

Performance Expectation(s):
5-PS1-1. Develop a model to describe that matter is made of particles too small to be seen.
5-PS1-2. Measure and graph quantities to provide evidence that regardless of the type of change that occurs when heating, cooling or mixing substances, the total weight of matter is conserved.
5-PS1-4. Conduct an investigation to determine whether the mixing of two or more substances results in new substances.
