A Hands-On Look at How Climate Change Affects Plants

Use photosynthesis to make plants grow. Manipulate light and carbon dioxide and see, in real time, how this affects photosynthesis. Young festival-goers enjoy blocking the light with their hand and seeing photosynthesis fall, then removing their hand and watching photosynthesis resume instantaneously. Older festival-goers can change light or carbon dioxide concentration in steps to see how this affects photosynthesis. We will have plants that have been used in the space program such as “space wheat” and "microtom" tomatoes.
