My favorite science experience is to put a green leaf in a small chamber. Then, given that there is enough light in the chamber, I like to see how the amount of carbon dioxide in the air within the chamber is reduced as the leaf photosynthesizes. During photosynthesis, the leaf is converting solar energy into carbohydrates. This photo of me was taken in Australia. Can you guess what kind of animal Iím with? If you guessed a kangaroo, you are right!
