What you will learn
See that leaves make sugar from carbon dioxide and water using light, give out oxygen, and that most of a plant is built from the air.
How to play
- Move the light, water and carbon dioxide sliders.
- Watch the sugar in the leaves and the oxygen bubbles, and see what holds the plant back.
- Answer three questions: what happens in the dark, what the plant takes from the air, and where its mass comes from.
- Then run your own experiment, like a plant kept in a dark cupboard, and test its leaf with iodine.
