Color Me Blue

In this activity, learners add dilute bleach solution to water that has been dyed with yellow, blue, and green food color. Using a chemical reaction (bleaching), learners can identify different components in a mixture. The activity also includes the opportunity to investigate the nature of variables, constants and experimental design. This activity guide includes extensions on page 10, which allow learners to investigate concentration and chromatography. Part of the 21-activity guide published by OMSI, No Hassle Messy Science with a Wow.
