Abstract
2. I choose this project because, I love plants and I love learning
about them and now, I know that the plants growmore
healthyin the natural light that artificial light.I solved the
problem by giving the plant water every day and at the same
time. In conclusion, the plant on the blue light was dying, but
on the other hand, the plant on natural light was growing
beautiful, blooming, and very healthy.
Problem statement
The problem is that the plant on the blue light is dying;
nevertheless, the plant on the regular light is growing
beautiful and healthy as it should be.
3. Materials
1.One pack of seeds
2.Two lights one blue and other white
3. Pencil, marker, and tape,
4. White scissors
5. Mulch, and plastic pots
6. Water
4. Conclusion
My conclusion was wrong mine was that the plant on blue light
was going to grow faster and healthier; However, I was wrong
it is the other way around.
5. Procedure
First I bought a little bag full of seeds, Then I opened the little
bag and divided the bag into 2 equal part.First, IFill the cups 2/3
full with soil the same amount of mulch in each plastic pot and
add same amount of seed pot. Next, I put water on the top.
Later, I recorded the results over the course of several weeks. The
plant on natural light already had leaf,while,the plant on blue
didn’t have anything. Finally, the plant grew the plant on the
natural light was beautiful with small flower everywhere and
really healthy the height was 12 cm; although, the plant with
blue light only had weak branch and small leaves , no flowers
it, the heightwas 6 cm looked like it was already dying.
Variables
First, you need to dig a whole on the ground and but the seeds
and then you cover it. Second, you need to put water on the
plant every day at the same time later on the plant starts to
grow the flower finally the plant is nice and healthy
6. Results
My results were that the plant on regular light was actually
nicely healthy and the plant on blue light is not doing good at
all it was dying.
7. Data
Plant A is in a natural light bulb, Plant B is in a blue light bulb
both of them have water at exactly 3:40 pm the picture the
pictures were taken once a week. They started to grow in
October and already had the flowers starting November.

Plant on Plant on blue
natural light light
9. Application
I learned the artificial light, will only support low-light tolerant by plants.
Most artificial light sources (fluorescent) do not provide the full visible light
spectrum that is required by plants for optimal growth, this results in plants
that are small spindly and sometimes discolored.Plants will grow better
under sunlight; artificial light lacks the complete spectrum of light provided
by the sun. However, they can never completely duplicate natural sunlight.
For this reason, I plant in my garden, nicely flowers plant that help with the
oxygen the human been need for life.
Hypothesis
My hypothesis that the plant on blue light is going to grow
really fast, healthy, and beautiful than the one on natural light

The person that helped me in my science fair project. First,
was my Mom, she helped me in my vocabulary, the pictures
and she also inserted the graphs and charts in my project.
Another personwas my Dad, he bought the materials, finally
my Grandpa helped me at remained me to put the water on the
plant and recorded data from them.
