Gizmo Warm-up
A chemical change. (or chemical reaction) occurs when one
or more substances, called reactants, are transformed into
different substances, or products. In the Chemical Changes
Gizmo, you will look for evidence of chemical changes by
looking at changes you can see, touch, or smell.
To begin, check that Reactant 1 is Sodium and Reactant 2
is Water. Sodium is a metal so soft you can cut it with a knife.
