RAHWAY—Rahway Middle School eighth graders have been studying the properties of matter in their science classes. As an investigation, students applied heat to a variety of substances and observed the changes made in the substances’ appearance during and after heating.
They learned that applying heat to a substance may result in the formation of a new substance—a chemical reaction—and that is a yet another characteristic property of the substance. The students also learned how to identify the reactants and products in a chemical reaction and how to write and balance a chemical equation.
