Learn how plants take in nutrients with this fun and easy celery science fair project.
In this celery science project for kids children will see how water travels through plants. During this experiment children will learn about osmosis. This is a simple science experiment and perfect for young scientists. This is a great science fair project for children Kindergarten-2nd grade.
Scientific Method
In this experiments students will follow the scientific method
- Ask a question
- formulate a hypothesis (what do you think will happen?)
- Conduct the experiment
- Gather data/Analyze
- Conclusion
Question?
In this experiment children will put celery in colored water. They are going to ask the question: How does water travel from a plants roots to the leaves? How do plants take in nutrients?
Hypothesis
In this experiment you will be using food coloring and celery. You will be observing the celery for 24 hours. What do you think is going to happen to the celery? How do you think water travels from the root of the plant to its leaves?
Experiment
In this experiment you will putting a celery stalk in a glass of colored water. You will observe the celery for 24 hours.
Materials
- 6-8 drops of food coloring You can do this experiment with one food coloring or you can do this with as many colors as you choose. If you are going to use one color we suggest using blue or red.
- Celery sticks you will need one celery stick for each color
- Tall glass (one per each color)
- water
Procedure
Step 1: Pour water into the tall glass until it is half way full.
Step 2: Add 6-8 drops of food coloring to the water. Make sure the water is a nice bold color.
Step 3: Place your stalk of celery into the glass with its leaves sticking out.
Step 4: Put the glass in a window where it can get the sun.
Step 5: Observe the celery for a 24 hours.
Gather Data and Analyze
What happen to your celery? Did the leaves of your celery change color?
The leaves of your celery should have turned to the shade of the water, why?
Osmosis! The leave of the celery will turn to a shade of the colored water. Celery is a vegetable and vegetables are plants..
Plants absorb minerals and water from the soil.
These minerals and water make the plant heathy and able to grow. When the water and minerals are absorbed in to the plant they flow through the plants cells.
The process where the water flows across the plant’s cell wall to enter the plant cell is called osmosis.
The colored water traveled up the celery and into its cells
