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

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…

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.

In this inquiry activity, students learn the process of photosynthesis and the function of the stomata. They then do an experiment to determine the location of the stomata- AWESOME!!!This takes about a week to see results!
