Bubbling Plants Experiment to Quantify Photosynthesis - YouTube

WebDuring photosynthesis, plants convert light, water, and carbon dioxide from the air into oxygen and sugars. In this activity, you will be able to observe the oxygen production in leaves by doing a floating leaf disk experiment. You can also find out how quickly plants produce oxygen, and what variables affect photosynthesis. Webput a piece of pondweed into a test tube of water shone light from a lamp with a red light bulb onto the pondweed counted the bubbles of gas produced by the pondweed every minute for three minutes.
