Our class decided that a plant would need light, water, and air to grow. We decided to test it by taking each of these things away from one sweet pea plant.
- One without water, in a tube.
- One without carbon dioxide, in a bag.
- One without light, in a box.
- One with everything!
The plant that has everything is called the control.
What do you think will happen to the plants that do not have something?
