Bromothymol Blue reacts to the acid in breath and changes from blue to yellow.  Great experiment when studying the respiratory system!

In this activity 'Demonstrating Photosynthesis with Bromothymol Blue' students use Bromo blue to photosynthesis occurring. Students use the indicator to show the presence of Carbon Dioxide and the lack of its presence after it was used by a sprig of elodea.

This is a fool-proof lab to demonstrate photosynthesis and respiration in aquatic plants. This lab works great when teaching about the carbon cycle as well. In this lab students will learn that plants only do photosynthesis in the light and in the dark cellular respiration occurs. Materials needed (per group): 4 test tubes with lids or parafilm, water, bromothymol blue, straw, elodea or other aquatic plant, test tube rack, aluminum foil, light source, and a goldfish is optional for an…

Phenol Red and Bromothymol Blue

Biology Lab: Characteristics Of Life. In this lab lesson plan , you will work with Bromothymol Blue, an indicator used to determine the presence of carbon dioxide. When living organisms convert their food to energy during respiration, they give off carbon dioxide as a waste product. You will be using yeast in this lab to observe the characteristics that indicate that they are living. $
