What do plants need to grow?

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?
