Here’s a neat experiment you can do to measure the rate of photosynthesis of a plant, and it’s super-simple and you probably have most of what you need to do it right now at home!



You basically take small bits of a leaf like spinach, stick it in a cup of water that has extra carbon dioxide in it, and shine a light on it. The plant will take the carbon dioxide from the water and the light from the lamp and make oxygen bubbles that stick to it and lift it to the surface of the water, like a kid holding a bunch of helium balloons. And you time how long this all takes and you have the rate of photosynthesis for your leaf.

  1. Yes, give it a try! When doing this experiment, I usually suggest trying several different versions using different leaves so you can identify the best one.

  2. I don’t have spinach. Will lettuce or grass work?
