Carolina Chemonstrations®: Rainbow Indicators Kit



Here's a colorful introduction to pH indicators for your chemistry class. Amaze your students as you add colorless solutions to seemingly empty beakers and produce a rainbow of colors. Students begin by making a prediction about the results based on prior knowledge. After viewing the demo, they construct an explanation of their observations on a particulate level and then answer big-picture questions that ensure their understanding of the underlying concepts. It's a mesmerizing way to start your school year and a must during an acid/base unit. This demonstration requires approximately 5 min of classroom time and materials are sufficient for 5 demonstrations.
