Description:

Learners investigate how temperature affects the rate of chemical reactions by observing how steel wool reacts with various types of Kool-Aid solutions at different temperatures. The reaction is monitored as the color fades in the Kool-Aid solutions. Background information includes how the dyes change color from an oxidation-reduction reaction. Extensions include investigating how surface area and concentration affect reaction rate. Part of the "No Hassle Messy Science with a Wow" activity guide by OMSI, where all activities use only household materials.
