Product Details

Acid–base indicators have been around for centuries and can be made from multiple materials. In this lab, students study the indicator properties of blue maize flour, also known as blue corn flour. First, students create a color guide using a blue maize flour suspension. After viewing the colors of the flour indicator at various pH values, the blue maize indicator is used to determine the pH of lab chemicals and household liquids. Have fun exploring the pH of various solutions with this vibrant indicator!

Complete for 30 students working in pairs.

Performance Expectations

MS-PS1-1. Develop models to describe the atomic composition of simple molecules and extended structures.
MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
HS-PS1-1. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
