Plant Growth Experiment Questions

The video introduces the basic needs of plants: water, soil, and sunlight. It explains photosynthesis and sets up an experiment to test plant growth under different conditions. The experiment involves growing four plants, each missing one essential element. The video guides viewers through gathering materials, preparing, and conducting the experiment. Observations are recorded in a plant journal, and the video concludes with a call to action for viewers to share their own experiments or questions.
