Can Plants Grow Without Sunlight or Water?
Grade Level: 2nd-4th; Type: Botany
Objective:
Test whether plants can grow without sunlight and water.
Research Questions:
How do plants make their own food? Plants contain a green pigment called chlorophyll, which can make food from water and energy from sunlight. But what happens when you deprive plants of water and sunlight? Can they live? For how long?
Materials:
- Potted plant
- Pen and paper
Experimental Procedure:
- Place your potted plant in a dark room or closet.
- Do not water your plant.
- Check on the plant every two days for two weeks, and observe what happens.
- Record your results.
Terms/Concepts: Plants; photosynthesis; primary producers
