How does the color of the light affect the growth of a plant

  1. 1. How does the colorof the light affect thegrowth of the plant?.Brithney HernandezMrs.Avalos 4th gradeNovember 29,2012Abstract
  2. 2. I choose this project because, I love plants and I love learningabout them and now, I know that the plants growmorehealthyin the natural light that artificial light.I solved theproblem by giving the plant water every day and at the sametime. In conclusion, the plant on the blue light was dying, buton the other hand, the plant on natural light was growingbeautiful, blooming, and very healthy.Problem statementThe problem is that the plant on the blue light is dying;nevertheless, the plant on the regular light is growingbeautiful and healthy as it should be.
  3. 3. Materials1.One pack of seeds2.Two lights one blue and other white3. Pencil, marker, and tape,4. White scissors5. Mulch, and plastic pots6. Water
  4. 4. ConclusionMy conclusion was wrong mine was that the plant on blue lightwas going to grow faster and healthier; However, I was wrongit is the other way around.
  5. 5. ProcedureFirst I bought a little bag full of seeds, Then I opened the littlebag and divided the bag into 2 equal part.First, IFill the cups 2/3full with soil the same amount of mulch in each plastic pot andadd same amount of seed pot. Next, I put water on the top.Later, I recorded the results over the course of several weeks. Theplant on natural light already had leaf,while,the plant on bluedidn’t have anything. Finally, the plant grew the plant on thenatural light was beautiful with small flower everywhere andreally healthy the height was 12 cm; although, the plant withblue light only had weak branch and small leaves , no flowersit, the heightwas 6 cm looked like it was already dying.VariablesFirst, you need to dig a whole on the ground and but the seedsand then you cover it. Second, you need to put water on theplant every day at the same time later on the plant starts togrow the flower finally the plant is nice and healthy
  6. 6. ResultsMy results were that the plant on regular light was actuallynicely healthy and the plant on blue light is not doing good atall it was dying.
  7. 7. DataPlant A is in a natural light bulb, Plant B is in a blue light bulbboth of them have water at exactly 3:40 pm the picture thepictures were taken once a week. They started to grow inOctober and already had the flowers starting November. 12 10 8 6 4 2 0 Plant on Plant on blue natural light light
  8. 8. BibliographyMy bibliography is:www.google.com;www.qacollections.com/Photosynthesis-Science-Projects-for-the-Four., and www.animalplanet.com
  9. 9. ApplicationI learned the artificial light, will only support low-light tolerant by plants.Most artificial light sources (fluorescent) do not provide the full visible lightspectrum that is required by plants for optimal growth, this results in plantsthat are small spindly and sometimes discolored.Plants will grow betterunder sunlight; artificial light lacks the complete spectrum of light providedby the sun. However, they can never completely duplicate natural sunlight.For this reason, I plant in my garden, nicely flowers plant that help with theoxygen the human been need for life.HypothesisMy hypothesis that the plant on blue light is going to growreally fast, healthy, and beautiful than the one on natural light
  10. 10. AcknowledgementsThe person that helped me in my science fair project. First,was my Mom, she helped me in my vocabulary, the picturesand she also inserted the graphs and charts in my project.Another personwas my Dad, he bought the materials, finallymy Grandpa helped me at remained me to put the water on theplant and recorded data from them.
