This activity will be used prior to any direct instruction for photosynthesis. In this inquiry lab, students design and conduct simple experiments using elodea and Bromthymol blue to determine whether plants consume or release carbon...

Students learn a simple technique for quantifying the amount of photosynthesis that occurs in a given period of time, using a common water plant (Elodea). They can use this technique to compare the amounts of photosynthesis that occur...
