Bubbling Plants Experiment to Quantify Photosynthesis

Type of Resource



From TeachEngineering - 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 use this technique to compare the amounts of photosynthesis that occur under conditions of low and high light levels. Before they begin the experiment, however, students must come up with a well-worded hypothesis to be tested. After running the experiment, students pool their data to get a large sample size, determ

Performance Expectations

5-LS1-1   Support an argument that plants get the materials they need for growth chiefly from air and water.

MS-LS1-6   Construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms.
